This article looks into it. Roller pigeons were bred to roll, these pigeons have been bred for a genetic deficit that causes them to roll mid-air. These seizures make them look like they are performing backward somersaults while flying. The reason these pigeons were bred to roll was to act as a form of entertainment for humans.

Our fascination with selectively breeding animals has extended to pigeons. Today there are a variety of pigeons that have been bred to perform certain tasks, roller pigeons are one of them.

Birmingham rollers, also known as roller pigeons, are birds that are bred for a genetic deficit that causes them to seize in mid-air. As they seize they roll back and it looks like they are performing backward somersaults while flying. The birds do not become injured as they recover before they hit the ground. Breeders of these birds take advantage of this trait and train the birds to have seizures in synchronization for shows and events.

Roller pigeons were once a flying bird but now they are bred selectively for show and entertainment. Yes, other pigeons roll, some pigeons roll like roller pigeons and others roll similarly to roller pigeons. There are no treatments.

Individuals of these breeds, or of other breeds, that show these behaviours to the extent that they risk harming themselves should not be used for breeding. For further details about this condition, please click on the following: these link to items down this page.

Tumbler pigeons have been recognised as a distinctive breed type for centuries and the selective breeding for their behavioural characteristic was highlighted by Darwin We may believe that some one pigeon showed a slight tendency to this strange habit, and that long-continued selection of the best individuals in successive generations made tumblers what they now are; and near Glasgow there are house-tumblers, as I hear from Mr Brent, which cannot fly eighteen inches high without going head over heels.

The behaviour in most tumbling breeds is only noted during flight and is not present from fledging but rather appears when the birds are a few months old. Affected birds fly normally most of the time but have intermittent episodes of falling from the sky, whilst somersaulting backwards. Birds which tend to multiple somersaults are called rollers. Usually the birds regain control and continue to fly on in a normal manner.

Owners call this a rolldown. A more extreme form of the somersaulting abnormality is shown by the Parlor tumbler breed. This may be due to some defect in balance centres of the brain. The causes of this behaviour have been investigated to some extent. A problem with the vestibular apparatus of the inner ear the sensory part of the balance mechanism was initially considered but then rejected by Mowrer He went on to conclude that the pathology that resulted in this behaviour was likely to be within the vestibular parts of the cerebellum — the areas of the brain that are connected to the inner ear and which control movement and balance.

Smith et al showed that drugs affecting neuronal transmission in the brain reduced the somersaulting behaviour of Parlor tumblers which suggests that some abnormality in serotonin transmission in the brain may be the cause. Return to top. Collision with the ground, trees or building when tumbling is likely to result in injuries that may be severe and painful. Pigeons are flock animals and it is normal for them to try to keep up with the rest of the flock and they are likely to be distressed if unable to do so.

It has been suggested that occasional tumbling is a normal behaviour of pigeons — which might be used, for example, in attempting to escape from a flying predator such as a Peregrine falcon. Whether or not this is true, there is no doubt that the behaviour is very exaggerated in the tumbler breeds. It is difficult to know how the bird experiences this behaviour and whether it is deliberate or not, but there is no doubt about the welfare consequences when it leads to severe physical injuries caused by collisions during somersaulting.

All individuals of the affected breeds show these abnormal behaviours but to varying degrees. Typically, the more severely affected birds are those that are valued more highly by owners — it is this that has driven selection for this abnormal behaviour.

Columbidae - Please see also Doves Pigeon Information Intelligence and Amazing Facts Breed Photo Gallery Tumbler Pigeons have been named for their ability to spin and "tumble" in flight.

Description Tumbler Pigeons occur in a wide variety of specialty breeds, plumage colors, body types, as well as feather configurations. The neck is usually thick. It shouldn't be too short. Successfully keeping tumbler pigeon: Housing: They require a well-built pigeon loft that allows them to get out and about as they wish to fly, or to return to their home loft to feed, find protection from adverse weather conditions, and give them a safe place to reproduce. Feeding Tumblers are not picky as far as food is concerned.

Genetics : Certain genes and gene variations may increase your susceptibility. Environmental exposure: New cases of polymyalgia rheumatic have a tendency to come in cycles and might expand seasonally.

This indicates that an environmental trigger, inclusive of a pandemic, might play a function. However, no unique virus has been proven to cause polymyalgia rheumatic. There is not any specific test for testing fibromyalgia, but some doctors use a check list that has 18 particular trigger points often found in the patient who may be suffering from the fibromyalgia. Your physician might also ask you for some blood tests to determine the exact stage. Some of these tests incorporate physical exams and therapeutic history survey, blood tests for finish blood check and swelling parts, imaging tests to recognize polymyalgia from different conditions with comparable manifestations, and observing for giant cell arteritis by giving careful consideration to the nearness of cerebral pains, jaw ache, sentimental, blurred or double vision, and scalp tenderness.

To treat fibromyalgia, there are medications , elective cures, and way-of-life propensities that may help manage pain and enhance better sleep. Your clinician may prescribe pain medicine or antidepressants to help treat the ache, exhaustion, dejection, and tension that accompanies the sickness. Moreover, your specialist may prescribe physical workout, moist heat, daily aerobic workout, relaxation, and stretching to better manage your symptoms.

Polymyalgia rheumatica is caused by inflammation. Age is a big one — almost no one under age 50 gets PMR, and the likelihood of getting it increases with age, according to a BMJ review.

The average age when PMR symptoms start is Women also have a higher risk of polymyalgia rheumatica; about three quarters of PMR patients are female.

Genetics could also play a role. People of northern European descent have a higher risk than other ethnic groups. Here are fibromyalgia symptoms to be aware of. But there are some key differences between fibromyalgia and polymyalgia rheumatica. For one thing, the average onset age of fibromyalgia is 35 to 45, which is far younger than would be expected with PMR. The nature of the pain is also different — fibromyalgia develops when brain receptors start signaling pain without a trigger, while PMR is driven by inflammation.

This also sets it apart from wear-and-tear osteoarthritis. Meanwhile, the placement of the pain — the shoulders and pelvic area — sets it apart from other types of inflammatory arthritis like rheumatoid arthritis, which tends to show up in smaller joints like the hands, wrists, and feet, adds John Davis III, MD, a rheumatologist with Mayo Clinic.

American College of Rheumatology. Camellino D, et al. Update on treatment of polymyalgia rheumatica. Docken WP. Treatment of polymyalgia rheumatica. Dejaco C, et al. Giant cell arteritis and polymyalgia rheumatica: Current challenges and opportunities.

Nature Reviews: Rheumatology. Arthritis Foundation. Vasculitis Foundation. Buckley L, et al. With medication, you may see a major improvement in your polymyalgia symptoms in just a few days.

Your doctor should find the lowest dose of the medication to manage your symptoms and most patients can stop taking corticosteroids after one to three years, depending on the severity of your symptoms 8.

Research suggests that patients who experience a relapse were more likely to have started treatment on higher doses of corticosteroids or faster medication tapers at the end of treatment Apart from their name and main symptom, fibromyalgia and polymyalgia have little in common. The way each condition affects your body is very distinct and the treatment methods are also very different 5, 13, The main difference is that polymyalgia rheumatica is an inflammatory condition, and fibromyalgia is a non-inflammatory condition.

Because of this, polymyalgia rheumatica responds to treatment with anti-inflammatory medications. Fibromyalgia and statin induced myositis is associated with tenderness. In some cases, GCA affects the arteries going to the eyes, which can result in blindness. The reason that polymyalgia and GCA are linked is unclear, but some experts believe both illnesses could be related to similar genes and may be different ways the same disease process manifests 7.

You can develop GCA before, during or after your polymyalgia diagnosis

And second: the D and the D have different controls, it is very personal, but I like more the proffesional controls of the D, being the same as my previous camera. One control that Nikon missed out on for the D is a custom user mode. This is available on the D and I love it and absolutely miss not having on the D It is such a time saver to have a custom mode all set up and available with a quick turn of the mode dial. I also wish they would upgrade the firmware to allow bracketing above a 1 EV step, like they have in the D It would make shooting HDR more fun and mean I spend less time throwing away unwanted exposures.

Another way to look at it: Handheld? Take the D I have a DE and a D3s and the tripod question is pretty much what determines which body goes out the door with me. Love this article, I used to be a Nikon man back in the film days but quickly turned to Canon in the digital age.

I also agree with you on the file sizes, they are way more manageable on the D Not found on the D D can use both CF and SD. I love the D The image quality is revolutionary. It is incredible for landscape work. It does, however and as you said, come with the cost of large memory and time sucking files. A very interesting discussion!

I am also on the fence in this decision. I am leaning towards the D right now. In UW-photography the main investment is the Housing, approx twice the cost of the D Therefore, I will be stuck with the decision that I make now for about 10 years or so.

Well, that is atleast what I tell my wife :- I am pretty sure that during thes 10 years my Computers will get quicker and the memories will get faster, bigger and cheaper… So, this issue will be somewhat mooted over the years! While diving I do a lot of Macro. There the FX format has some pros an cons compared to a DX format. The main divider here is the depth of field! You get a nicer Bokeh, blurry background with FX, but a lot less keepers due to the decreased depth of field in FX!

With a D you have the chance to use both, depending on the situation! I bought the D on the Friday after the Wednesday availability.

I returned it Saturday due to the diopter control failing. I bought it again on Sunday and have had it since. Problem with early adoption is that LR and Photoshop cannot open the raw files as it is too new. Since then, LR 4. Those wondering about file size are right to be concerned. Raw files are hard drive killers due to size, so make sure you have lots of storage for your photos with this camera.

Lens quality also comes into play as using old or third party lenses will show every defect in your glass with this much detail in each file. Low light capability is awesome, autofocus area is not. The D has a slightly larger AF area. Lack of patience with Nikon produced this sale. I was waiting for the mythical D but it is lost in the forest along with Bigfoot so far. I gave up waiting to upgrade my aging and battery hogging D and bought the D Now I have a ruggedly built bracket button capable D, which is heavier and better built than the D for my DX body, as well as the latest computer as camera in the D for my FX body.

Having said all of this, glass is still by far the best investment you can make. Bodies come and go, quality glass is usable on any Nikon built since That lens is over 20 years old and works just fine.

Canon has changed their lens mount repeatedly over the years, so I stick with Nikon. Hope this real world advice helps those trying to decide what to do. It looks like a great camera. I did wait until it came out before I decided to go with a D as an upgrade from my D Had the price been a bit lower, or the focus system a bit higher end, maybe… It was a difficult enough decision that I made myself a pro vs.

As to the D, on another photography blog a few weeks back, the camera was compared to a Ferrari that routinely just gets driven a few blocks in city traffic.

Where I live, the mountains of western Colorado, and often shoot, the high deserts of Utah, the camera serves more like a good crossover SUV.

I feel the same way about the extra dynamic range that I believe the D offers over the D it replaced. It also works fine for the admittedly not hyper-fast sports I shoot: kayaking, mountain biking, rugby and rodeo.

To sum this very well written article up: If you have to ask which cmaera is right for you, go with the D Not true! Maybe buying X is correct for some, but for others Y will be better. The truth I sold my D om Tuesday. Scott thanks for the comparison, I am not a pro and decided to go with the D and you have reaffirmed by purchase.

So far it has done everything I needed and the prints are turning out great. Also thanks for all you do for the Photoshop users, your training site has helped me greatly in speeding up my learning curve. Great post Scott. I value your opinion. I just replaced my D with the D I have wanted to upgrade to FX and was very excited when the D was announced.

I am not concerned that the D, D, DE and D4 all have the same insides, that they are all the same cameras designed and produced at the same time with the same insides, differing only in exterior casing and when Nikon chose to announce them and that they produce the same images with the same processing power, the same LCDs, the same green-shift problems and identical AF controls. I am not concerned that the D may be a D with more megapixels or a D replacement.

I am not concerned that the D is better in many aspects. The D is the perfect camera for me and meets all my needs and expectations.

Being a D owner and having written a book on it Nikon D From Snapshots to Great Shots — shameless plug I can tell you that I am asked this question all the time.

I have not used the D but asked about whether or not to buy a D my answer is that it really depends. It certainly is not the camera for everyone. Most wedding shooters I know are shooting well over a thousand images per event and I can fit around raw images on a single 64GB card. I would however use it for the formal shots, especially those that might end up as big prints above a fireplace. If you shoot landscapes, you will love the great detail in your images but, like Scott said, be prepared for some huge files if you are into HDR or panos.

If you shoot wildlife, you will probably love this camera because it has some amazing detail, but not necessarily if your subject is one that moves a lot. The slow frame rates will mean a lot of missed photos. If portraits are your thing, be prepared to do a lot of retouching because the skin detail is crazy and maybe more than you want to deal with.

One other thing to consider when considering a D is the condition of your computer system that you use for processing images. You are going to require a lot of ponies under the hood and a lot of RAM to work with all those pixels.

These files are huge, even in their raw state, which means you will need to give some serious thought to your storage needs. I only store my active shoot on my MacBook because I am afraid I will run out of disk space. All that being said, I really love my D The good thing about the D is that it allows you to choose the resolution size for your particular needs at the time.

No, just for JPEG. I wish if it is available for RAW. The other alternative is shooting DX to reduce the size but it is useless. Good recap of what Scott was saying. Everything mentioned here I recommend to the new photographers reading this to squeeze into proposals because not many people understand the value of the photography when you give that price…. I love my D for most things. I upgraded from a D that I bought last year to see if I would enjoy photography.

Turns out I do very much I enjoy tweaking the mega-big files in photoshop, and watching my computer churn away processing HDR images. Then I took it to my first football game that I had to cover : Not that I expected it to be perfect, but i was disappointed. The next day I bought my D4 which is great for action. Your lesson was learned. Use a scalpel for surgery, use hedge trimmers for landscaping.

I own the D and love it. Having said that, if the D had come along first I would have gone with it and been happy. I was upgrading from my 5 year old D Needed a new PC regardless and the new set up handles the files just fine. Love the video quality too. The D offers a lot of options for file size. But my other 12mp FX camera sees the bulk of the night time shots in that I can shoot in RAW still for appropriately sized file sizes. Where is the D…. D is overkill, and as someone said below, its like a D…lacking needed features.

I will not buy either one and will wait till Nikon does the D right. If I want to switch to 36x24mm, I would continue saving also the last more bucks that are needed, to get the D If you are afraid of the image size, just shoot in S or M size! Fully Aggree — but the only issue with D I see is the CAM Focussing module; It seems to be the same sluggish one as in D and was the reason for me to switch finally to D; Hopefully Nikon improved it — With D I had a lot of mis-focussed pictueres — my D and D were much more reliable in that aspect.

Hello Scott. I sent the d back. Now I am trying to decide about waiting for Nikon to remedy the sensor issues with the d or get the d Is the d sensor really a problem?

But everybody should be aware of the possible seems to be very very common! Hello Cathy — where can you buy a new D? Thought it was discontinued. It may be a pain in the butt, but I would probably buy it from my local camera dealer as opposed to online because they offer lifetime sensor cleanings for any camera bought from them. Should be enough to get that excess oil off the shutter. Worked on mine anyway. They dropped a few of the features that I love on my Ds going to the D, which are present on the D For any travel or action photography i.

The D is much lighter and easier to carry around than the D, and the D, at least in my opinion, produces slightly sharper images all other things being equal. So I think that another use for the D is the Macro Photography. I can see them only in Firefox. Anyone got the same? Is that possible? Can a hack be created to allow for the D to take smaller RAW files?

Just wondering. As of now, the D is not recognized as a pro body according to Nikon Professional Services. Any thoughts? Sometimes I keep thinking that Nikon will surprise us all with a new firmware for the D; sometimes I keep thinking another pro body will be announced very soon.

David: Can Nikon release a firmware update with that stuff? Will they? I do not agree that the D is the replacement for the D The product name number for the D is correct in my opinion.

It is a entry level version of the D Sure some things are a lot better than D technically and image sensor vise even the D or whatever it is called is probably technically better than the D but body vise the D is a professional camera and the D is not. Im not saying you cant take professional pictures with the D though For me a AF-ON button is critical.

I have experienced this problem myself on my D which I think is a great little camera but I rarely use it mostly for this reason. Another thing that is important to me is a great viewfinder and you cant even compare the viewfinder in D and D and I need to be able to attached this rubber thing that blocks out some light..

For sports and action it is sure too slow but for travel and everyday shooting it is more than enough. And sure 24 MP would be far more than enough for me but 36 is okay too..

Great post! I was one of those guys that admitted I may have made a mistake buying the d because of the large files size. Now I can have all the detail and capabilities of a raw file but in a nice small jpg sized file. I would love to hear your opinion on this feature in Lightroom. The D gives you more leeway to crop a shot in tight later and still have a useable image- one that can still be blown up relatively large.

I did some extreme crops recently and it worked out nicely. The less megapixels you have to work with, the more difficult that becomes. Though, you know a lot more about this stuff than I do. Stick the D into 1. Downside is that you lose a little on the wide end but you kinda get more on the long end. You still get 15mp with the 1. With the grip it goes to 6fps, which is still a couple fps slower than a griped D, but not too bad. One of the reasons to buy a D or a D is for the full frame sensor.

If you want a cropped sensor, then the D, D, D etc all out there for a lot less.. Just release a firmware that will enable D owners and that would-be D owners would love! Give them an option to obtain in camera smaller RAW files at will— whatever size that would be mathematically correct! Give an additional choice of file sizes for the D RAW shooters!

Make the D a greater upgrade for the D lovers! Make the outstanding D stand up to the more moderate RAW image sizes that Canon has in their comparable camera line-up! All or most Nikon owners will be happy you did! Release an updated firmware, Nikon! If you shoot in 1. I mean if Nikon made a full frame shot into a smaller raw it would be interpolated, so not raw data….

I think it is really fascinating that so many people love the D and yet at the same time want it to be upgraded. I agree with the comments above re the differences beyond the sensors.

There are some tradeoffs compared to the pro-level D and D bodies that trouble me. The , in my opinion, is a pro sensor in a consumer body so the decision also includes ergonomics.

Nicely, Nicely done Scott. I have the D Love it. It is getting a little long in the tooth and is ready for a replacement, but neither the D nor D fulfil what I am looking for.

From past few days I had a fear that I would have made a bad choice by purchasing D instead of D, after reading this I am relived and happy that i made a good choice.

I mainly shoot wedding and portraits, initially as budget was an issue i went with the kit lens 3. I like the 50mm but it cannot be used at all times. I find the ability to crop a 36MP image by a 1. You can effectively mount a mm and use it as a mm while still getting 15MP. You can get reach when needed and capture amazing details when shooting landscapes for instance. Yes, they both have their strengths and weaknesses, and every single shooter has unique needs as well, which is why other reviewers wisely point out the pros and cons, then let savvy users make up their mind as to which is best for them.

Only sycophantic sheep pick their camera based on the opinions of online opinion merchants like Ken Rockwell, Thom Hogan, and yes Scott Kelby. Nice review! I have rented the D and tried it out over a number of weeks shooting a couple of weddings, events, portraits etc. I agree!! I have the D and really like it.

Dear Scott, I think you are right on. There IS a dust problem with the sensor by the way… mine has it… but I will just have to wait until Nikon finally owns up to it and get it fixed. Sync speed? The D is exciting because it treads on medium format territory and does it at 4 frames or 5 with the right parts a second.

Better yet, it is doing it with a great dynamic range and high ISO performance that had really only been seen previously on a Pentax K-5 in anything remotely approaching this size, capability, and price range. Another thing is that it brings the background closer and theres less distortion when using a lens length that provides same angle of view. I use a Mamiya with a Leaf 33mpx back and the D to shoot comercial fashion and editorial for magazines, so the complexities of skin tone play a vital role in what i do.

FX cameras only record at 14 bit. MF record at 16 bit. But this is cant really be seen until a print is made or seen on an IPS screen. The D has really changed where and when i can shoot. Sure, at low iso, nothing compares to the MF. Its all about time and place and when to use what, not better or worse. The D is truly unbelievalble though. I bought the wrong camera. I always feel that way right after I purchase a new camera.

Call it buyers remorse. An extension of my arm and my vision. So I upgraded from the D to the D So much better in so many ways, and yet so much more challenging! On a D-Town podcast, Pete Collins showed it off, and in a subsequent PhotoshopUser Magazine a few months ago, a favorable review was published. You might want to check it out. It WILL save your shoulder! The problem with this review is it does not address things like sports, action, birds in flight, differences in AF performance for moving subjects, low light focusing.

Because of this it is difficult to throw a blanket over one camera or another and say this is for you. So would you say someone that works in say low light theater or stadium sports that the D AF is better sure we know FPS could make a difference. I would of preferred something like for example , if you print big, landscape, portrait is better for D, sports low light photography and quicker AF, beginner, lower end lenses, those on a budget, D because saying the D is better kind of devalues your opinion.

Scott I really enjoyed reading your comparison. Really appreciate it and feel a lot smarter for having read it. It makes me so sad.. The D makes me a better more efficient photographer. Because of the 36mp on the D you can zoom in and crop the image and still print extremely high detail images. It is absolutely amazing at what you will see in images that I simply could not dream of with my D that I replaced. The D was amazing but if I did not have the zoom lens on when the shot required it the results were difficult to overcome.

I am certainly in the minority here…. I cannot understand the issue with file size…. Sometimes focus tracking is more important than FPS…what is the point when most are out of focus. The low light ability of this camera and the dynamic range is amazing.

I am still accepting how much I can push the images in post processing. This is a camera you have to get comfortable with. I am not there but the creative range it allows me to exist within is enough for me to love this camera. My only complaint is the fact that I still have not been able to make quick adjustments to sensor area use and fx or dx format mode.

I probably need to read up more on this camera. This camera is nothing short of amazing…so much in one body!

Excellent points! When shooting sports with a 2. But for me, it makes more sense to use an FX only when needed such as low light and a second DX camera for me D for sports. So for me, a D and a D makes more sense than just a D Shooting weddings I use both. Scott, I was one of those people who was on the fence when your post on this subject first came out last Friday, and I was strongly leaning toward the purchase of a D since I wanted a new D A few years ago, you told your viewers on one of the early D-Town TV podcasts, if my memory serves me right, that you chose Nikon over Canon because you just like the way the shutter sounds.

In my mind, it was that comfort thing that got you to buy a Nikon camera. Similarly, I think that deciding on one of these two new Nikon models is that internal comfort thing tells us which one we should buy. I was so close to buying the D, but I had a personal epiphany in my third store visit after trying out the D and the D What made me decide on the D?

And since I own a DS, the learning curve has been lowered for me. The D is a beauty and allows me to use it easily since I know where the buttons are, just like the DS. It felt awkward in my hands.

Thank you for your review of these two cameras and the comments shed a lot of light on the topic as well. One thing that I have not seen addressed is the importance of individual pixel size between the two cameras. The D pixel is 5. But, the price and the fps was really holding me back. I waited and waited and almost got one just before the D was released.

When the D was released, I realized it fit my needs more than the D for just the very reason you explained here. You gave your friend excellent advice in my opinion. Just got the D Incredible machine for my purposes. I gotta say, though: I still ogle and drool over the D when I see it. But I use a macbook pro and editing already takes long enough. I have a promote control, so my bracketing and time-lapse capabilities are far superior to the D alone.

Because difference in technical usability is concern only the way you use camera. So most outstanding advantages are FX sencor, new body, new technologies which stay above d :. Well said and well written, I do believe that the D is a better choice for general shooting, but I have been using a D and a D3X for years so it is a no brainer, however the build quality of the front and rear of the D is not for the working outdoor pro.

It is a unibody rear construction and a plastic front where the lens mount is attached much like the D Bought and sold the D at launch and now have a shiny D which I love.

All your comments here were spot on for me a jobbing UK freelancer and dance photographer. As you say the pipeline also got very choked and I found myself using my DX back-up body nearly all the time. This was a very interesting post! Hit me in the comments! Not concert etc. I know. Expect more comments and to see more photos more songs as well from me. I meant users my bad. Tucker a. Dwayne Tucker from DwayneTucker[dot]com. I think this excellent post and the thoughtful comments miss one possibility.

The D and D are not built for a sports shooter. And Nikon has set it up beautifully by creating a D6xx, D7xx and D8xx category all for different shooters with different needs. And at price points that slowly step us up in cost. You bet. For those folks wanting to massage their egos, by all means go for the D Am I right here? Within the spectrum of camera sensors, this places the review cameras among the large-sensor cameras that aim for top notch image quality.

Both cameras have a native aspect ratio sensor width to sensor height of While the two cameras under review share the same sensor size, the D offers a higher resolution of This megapixels advantage translates into a 22 percent gain in linear resolution.

On the other hand, these sensor specs imply that the D has a higher pixel density and a smaller size of the individual pixel with a pixel pitch of 4. Moreover, it should be noted, that the D is a somewhat more recent model by 7 months than the D, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of individual pixels. The resolution advantage of the Nikon D implies greater flexibility for cropping images or the possibility to print larger pictures.

The maximum print size of the D for good quality output dots per inch amounts to The corresponding values for the Nikon D are For many cameras, data on sensor performance has been reported by DXO Mark. The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance.

The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators. Many modern cameras cannot only take still pictures, but also record videos. Apart from body and sensor, cameras can and do differ across a range of features. The D and the D are similar in the sense that both have an optical viewfinder.

The latter is useful for getting a clear image for framing even in brightly lit environments. The adjacent table lists some of the other core features of the Nikon D and Nikon D along with similar information for a selection of comparators. The Nikon D and the Nikon D both have an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.

Both cameras feature dual card slots , which can be very useful in case a memory card fails. For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Nikon D and Nikon D and, in particular, the interfaces the cameras and selected comparators provide for accessory control and data transfer. Studio photographers will appreciate that the Nikon D unlike the D features a PC Sync socket , so that professional strobe lights can be controlled by the camera.

Both the D and the D have been discontinued , but can regularly be found used on eBay. Further information on the two cameras e. So what conclusions can be drawn? Is there a clear favorite between the Nikon D and the Nikon D? Which camera is better? A synthesis of the relative strong points of each of the models is listed below. If the count of relative strengths bullet points above is taken as a measure, the D comes out slightly ahead of the D 6 : 5 points.

The larger the sensor the more light the sensor captures yielding in better image quality. The more focus points the more flexibility in picking which part of the scene to focus on. They also give the image sensor a better probability in identifying the right area of the scene to focus on in more automatic modes. The number of megapixels determines the resolution of the images captured with the main camera.

A higher megapixel count means that the camera is capable of capturing more details. However, the megapixel count is not the only important element determining the quality of an image. With a higher light sensitivity ISO level , the sensor absorbs more light.

This can be used to capture moving objects using a fast shutter speed, or to take images in low light without using a flash. Fast continuous shooting is useful for catching action shots. With AF tracking, once you choose the subject and press the shutter release part way down, as the subject moves, the autofocus will follow it.

No more out of focus shots. Phase-detection autofocus is much faster than a contrast detection autofocus, allowing for sharper images. A faster maximum shutter speed allows taking pictures of fast moving subjects without blur. A two-stage shutter can help you take photos like a pro: just slightly press the button for the lens to focus, and then push it fully to capture the photograph. Videography 1. The maximum resolution available for videos shot with the main camera.

Although it may be possible to choose among other frame rates, those recordings usually have lower resolutions. A phase-detection autofocus system is faster than a contrast detection autofocus system. Even when recording scenes with a lot of fast movements, the videos are sharp and clear. When recording movies they stay focussed and sharp. A timelapse shows a long passage of time sped up.

A series of photographs taken from the same position over a long period is joined together to create a short video. It is great way to capture things like the setting sun, or clouds moving across the sky.

Nowadays, it is used to create film-like motion characteristics. Audio 1. A microphone port allows connecting external high-end or specialized microphones.

A stereo microphone allows to record audio files or movies in stereo without an external microphone. More microphones result in better sound quality and enable the device to filter out background noise.

This can be important with the complexity of some medical conditions requiring the input from many members of the health service.

Main idea and purpose are intricately linked. There are a few basic purposes for texts; figuring out the basic purpose leads to more nuanced text analysis based on its purpose.

Basic purposes of a text include:. The following video more fully explains these different purposes of a text, and adds a fourth, to share insights or feelings.

They also determine the pieces of the text you should analyze—content or language or both. You always need to analyze the text to see if the main idea is justified. Do the supporting ideas relate to and develop the main idea? Is the supporting evidence taken from recognized, valid sources?

Is the author arguing via language instead of evidence or facts? Persuasion and argument need to present logically valid information to make the reader agree intellectually not emotionally with the main idea. You usually need to analyze the text, since the text needs to present valid information in as objective a way as possible, in order to meet its purpose of explaining concepts so a reader understands.

You may or may not need to analyze the text. What is central idea example? Formulating a Central Idea Statement. Hafid Rivkind Explainer.

What is difference between theme and main idea? The main idea is what something is mostly about. Main ideas are typically found in a literary passage. Central ideas are found in an informational text. The theme is the lesson or message that the writer wants to get across in his or her story.

Jolanda Tzeluiko Pundit. How do you teach the main idea and supporting details? Kami Friedli Pundit. What is the main idea of the story? The main idea of a story is the central point or big picture concept that the reader should walk away with.

One of the best ways to determine the main idea is to identify things that are not the main idea. The main idea is not detailed; it's a concept that encompasses the entire book. Chase Kreuzer Pundit. What is the difference between a main idea and supporting details? It's simple; the main idea is the writer's message. Other writers provide supporting details and let their readers infer the main idea. This lesson will help you to distinguish between main idea and topic, to evaluate supporting ideas , and to find main ideas even when they are not directly stated in the text.

Step 1: Use Text Features. Step 2: Determine Text. A central idea is a main point that the author is making also called a main idea or a key idea. You can think of a central idea as a thesis statement: one sentence that states what the article is about.

A text could have more than one central idea. A central idea can always be supported with details from the text. What is the difference between a central idea and a main idea? Category: books and literature fiction. The two terms, when applied to ' ideas ,' mean essentially the same thing. There is one possible difference but it is a fine point.

Inflation and interest rates have major ramifications for the general economy, as these heavily influence employment, consumer spending, business investment, currency strength, and trade balances. Data on large time deposits, institutional money market funds, and other large liquid assets are published on a quarterly basis and are included in the M3 money supply measurement.

In the United States, the Federal Reserve's dual mandate is to balance unemployment and inflation. One of the ways it does this is by manipulating M2 money supply. M2 provides important insight into the direction, extremity, and efficacy of central bank policy.

The supply never shrank year-over-year YOY at any point in that period. These accelerated periods coincided with recessions and economic weakness, during which expansionary monetary policy was deployed by the central bank. Federal Reserve. Monetary Policy. Your Privacy Rights.

Until you pay the credit card bill, you have effectively borrowed money from the credit card company. With a smart card , you can store a certain value of money on the card and then use the card to make purchases.

In short, credit cards, debit cards, and smart cards are different ways to move money when a purchase is made. But having more credit cards or debit cards does not change the quantity of money in the economy, any more than having more checks printed increases the amount of money in your checking account.

One key message underlying this discussion of M1 and M2 is that money in a modern economy is not just paper bills and coins; instead, money is closely linked to bank accounts.

Indeed, the macroeconomic policies concerning money are largely conducted through the banking system. Read a brief article on the current monetary challenges in Sweden. Skip to main content. Module: Monetary Policy. Search for:. M1 M1 money supply includes coins and currency in circulation —the coins and bills that circulate in an economy that are not held by the U. Note that M1 is included in the M2 calculation. The Federal Reserve System is responsible for tracking the amounts of M1 and M2 and prepares a weekly release of information about the money supply.

Figure provides a breakdown of the portion of each type of money that comprised M1 and M2 in February , as provided by the Federal Reserve Bank. The lines separating M1 and M2 can become a little blurry. Sometimes businesses do not treat elements of M1 alike.

Changes in banking practices and technology have made the savings accounts in M2 more similar to the checking accounts in M1. For example, some savings accounts will allow depositors to write checks, use automatic teller machines, and pay bills over the internet, which has made it easier to access savings accounts.

As with many other economic terms and statistics, the important point is to know the strengths and limitations of the various definitions of money, not to believe that such definitions are as clear-cut to economists as, say, the definition of nitrogen is to chemists.

It is important to note that in our definition of money, it is checkable deposits that are money, not the paper check or the debit card. Although you can make a purchase with a credit card , the financial institution does not consider it money but rather a short term loan from the credit card company to you.

When you make a credit card purchase, the credit card company immediately transfers money from its checking account to the seller, and at the end of the month, the credit card company sends you a bill for what you have charged that month.

Until you pay the credit card bill, you have effectively borrowed money from the credit card company. With a smart card , you can store a certain value of money on the card and then use the card to make purchases.

In short, credit cards, debit cards, and smart cards are different ways to move money when you make a purchase. However, having more credit cards or debit cards does not change the quantity of money in the economy, any more than printing more checks increases the amount of money in your checking account.

In open operations, the Fed buys and sells government securities in the open market. If the Fed wants to increase the money supply, it buys government bonds. This supplies the securities dealers who sell the bonds with cash, increasing the overall money supply.

An increase in the supply of money works both through lowering interest rates, which spurs investment, and through putting more money in the hands of consumers, making them feel wealthier, and thus stimulating spending. Opposite effects occur when the supply of money falls or when its rate of growth declines. The decrease in the money supply is mirrored by an equal decrease in the nominal output, otherwise known as Gross Domestic Product GDP. The decrease in the money supply will lead to a decrease in consumer spending.

This decrease will shift the AD curve to the left. When the Fed sells bonds, the supply curve of bonds shifts to the right and the price of bonds falls. The bond sales lead to a reduction in the money supply, causing the money supply curve to shift to the left and raising the equilibrium interest rate. The first reason, then, why QE did not lead to hyperinflation is because the state of the economy was already deflationary when it began.

Another main difference is the speed that is used to transmit the data. While GPRS offered a maximum transfer rate of kbps, 3G can offer a maximum transfer rate of kbps, some can even offer up to 1 mbps. It is believed that in a few years, 2G would become obsolete with 3G taking the main stage. Though, right now it is gaining popularity, it is not compatible with the 2G infrastructure and some countries have not yet upgraded to the new infrastructure.

Thanks for the great site guys. I have one complaint though, Can you try to make your first paragraphs go straight to the differences between the two? The back ground may follow later. At times i feel like one wants the differences, and to those who may want to learn more, they can then continue reading the article. Am happy abot the site but i think you should get into more details about the greater difference between this two technologies.

With the exception of speed one cannot easily tell the difference and feel a more detailed approach will make this site much informative. However, in terms of basic information, the site has articulated what a leyman can understand about making informed decisions if one is to use these techmologies. This is really educative, its a site to bookmark. I would like to know please, can one send his question to you for solution?

Gender and Relationships. The safest place to be during a lightning storm is inside a relatively large, fully enclosed building not a small shed or an open garage, for example.

Do not use telephones, headphones or electrical appliances during the storm — lightning can travel through the wires and produce shocks to anyone using them. Yes, it is possible to get electrocuted by headphones when certain factors such as a faulty charger, power fluctuation, exposed wiring, or water are involved. Electrocution by headphones is not a real threat and extremely unlikely under normal circumstances.

Recently, several news reports revealed that plugging your earphones to listen to music while your phone is charging may lead to electrocution. Believe it or not, earbuds can damage your hearing in the same way that things like chainsaws and motorcycles can. That may seem weird because earbuds are so small. Anvil Crawlers are tree-like, horizontally-moving IC lightning discharges which tend to appear along the underside of thunderstorm anvils.

They can be seen by the human eye due to their slower speed relative to other lightning! Anvil crawlers are often very high-altitude events, and typically result in soft, rolling thunder due to their great distance from the observer.

Anvil crawlers can either occur independently completely within the cloud, or in connection with a cloud-to-ground discharge. It typically originates in the highest regions of a cumulonimbus cloud, travelling horizontally a good distance away from the thunderstorm before making a vertical descent to earth.

Bead Lightning is the name given to the decaying stage of a lightning channel which cools after a return stroke and its luminosity breaks up into segments. It describes a stage of a normal lightning discharge rather than a type of lightning. Ribbon Lightning occurs in thunderstorms with high cross winds and many return strokes The wind blows each successive return stroke sideways into the previous return stroke causing a ribbon effect Camera movement during the capture of a lightning photograph can also result in the same effect.

Staccato lightning is a CG lightning strike which is a short-duration stroke that often appears as a single very bright flash with considerable branching. And finally, what is ball lightning?!

Alternative and unquoted investments are inherently high risk and invested capital is at risk. Tax ramifications may vary depending on the investor's personal circumstances. Investment Guide. Calculus Capital Limited is not able to give advice to prospective investors about the suitability of the investments.

Prospective investors are recommended to seek specialist tax and financial advice before investing in any Calculus EIS Fund. An investment into a Calculus EIS Fund may only be made on the basis of reading in full the information set out in the relevant Information Memorandum.

When investing in the Fund, your capital is at risk. The value of shares and income from them may go down as well as up and despite the tax relief you may not recover the amount originally invested. An investment in smaller and unquoted companies carries a higher risk than many other forms of investment. Shares in unquoted companies are not readily marketable.

You should not invest in an EIS unless you can afford to lose some or all of your capital. An EIS investment is only appropriate for investors with a medium to long term investment horizon; the timing and extent of realisation cannot be predicted and may extend beyond five years.

It is not possible to allow a partial withdrawal of your investment. You may request a total withdrawal, but since many investments made by the Fund will be in unquoted companies, this may not be possible. Withdrawal within three years would lead to repayment of any tax reliefs received.

The tax benefits available depend upon your individual circumstances and these benefits may change dependent upon future legislation. This site uses cookies as described in our Cookie Policy.

By continuing to browse this site you are agreeing to our use of cookies. What else should you know? Rather, it refers to a collection of tax reliefs offered to investors by the UK government, when they choose to invest in companies which qualify for EIS status particularly start-ups. In another echo to the structure of VCTs, you must hold your EIS shares for a minimum of 3 years to claim the tax reliefs on offer.

This allows you to claim back some of the value of your original investment, in the event that it fails. The percentage you can claim back is equal to the highest rate of Income Tax which you pay. Clearly, both options provide powerful routes for investors to commit their wealth. Both offer significant tax reliefs, for instance, which are hard to replicate elsewhere. This is because VCT returns are typically paid to investors in the form of dividends, which are not subject to tax.

From an investment perspective, however, EIS clearly has an important advantage in the form of loss relief — offering substantial downside protection to EIS investors, whilst allowing you to take advantage of the investment upside potential.

EIS can also be a powerful tool within a wider estate planning strategy. This is because EIS investments are not usually subject to inheritance tax once they have been held for a minimum of 2 years. To browse our latest projects, we invite you to take a look at our portfolio here.

Therefore, the last measure of the example is only three beats in length i. Simple meters with other beat units the bottom number of a time signature are counted differently because a different note value gets the beat.

Example 17 shows a rhythm with a time signature:. A counted rhythm with the beat unit of a quarter note. Example 18 shows the same rhythm with the half note as the beat unit:. A counted rhythm with the beat unit of a half note. Example 19 shows the same rhythm with the eighth note as the beat unit:. A counted rhythm with the beat unit of an eighth note. Example 20 shows the same rhythm with the sixteenth note as the beat unit:.

A counted rhythm with the beat unit of a sixteenth note. Each of these rhythms sound the same, and are counted the same. They are also all considered simple quadruple meters.

The difference in each example is the bottom number—which note gets the beat unit quarter, half, eighth, or sixteenth. In simple meters, beams connect notes together by beat; beaming therefore changes in different time signatures. This is demonstrated in Example 21 :.

Beaming in two different meters. In the first measure of Example 21 , sixteenth notes are grouped into sets of four, because four sixteenth notes in a time signature are equivalent to one beat. In the second measure of Example 21 , sixteenth notes are grouped into sets of two, because two sixteenth notes in a time signature are equivalent to one beat.

Please note that beaming is sometimes not used in vocal music, although it is almost always used to connect notes sung on the same syllable. If you have not sung a lot of beamed music, you may need to pay special attention to beaming conventions, until you have mastered them. In Example 22 , the eighth notes are not grouped with beams, making it difficult to interpret the triple meter:.

If we re-notate the above example so that the notes that fall within the same beat are grouped together with a beam, it makes the music much easier to read, as seen in Example 23 :. Rhythms that are beamed according to the meter are usually easier to read. Note that Example 22 and Example 23 sound the same, even though they are beamed differently.

This beaming helps because the ability to group events hierarchically is an important part of the human perceptual experience, and the visual parsing of notated musical rhythms is no exception. We have a hierarchy in the form of a metrical structure, and we use our notational tools to show it!

Example 24 shows several different ways to beam beats in this same time signature:. Each line starts with unbeamed notes on the left, and the same rhythm beamed properly where applicable on the right. The first line does not require beams because quarter notes are never beamed, but all subsequent lines do need beams to clarify beats. The stems of notes can point either upwards on the right side of a note or downwards on the left side of a note. For notes above the middle line, the stem points downwards, and for notes below the middle line stems point upwards.

Notes on the middle line can point in either direction. This is shown in the first measure of Example 25 :.

As you can see in the second measure of Example 25 , when notes are grouped together with beams the stem direction is determined by the note furthest from the middle line. On beat one of measure 2 this note is E5; E5 is above the middle line, which means down-stems are used. On beat two of measure 2 this note is E4; E4 is below the middle line, which means up-stems are used. Flagging is determined by stem direction.

Notes above the middle line receive a down-stem on the left and an inwards-facing flag facing right. Notes below the middle line receive an up-stem on the right and an outwards-facing flag facing left.

Notes on the middle line can be flagged in either direction, usually depending on the contour of the musical line. This is demonstrated in Example 26 :. Conducting also depends on the meter of the piece; conductors use different conducting patterns for the different meters.

These patterns emphasize the differences between the stronger and weaker beats to help the performers keep track of where they are in the music. But the conducting patterns depend only on the pattern of strong and weak beats. Note that this means that children can be introduced to the concept of meter long before they are reading music. Meters can be classified by counting the number of beats from one strong beat to the next. Meters can also be classified as either simple or compound.

In a simple meter, each beat is basically divided into halves. In compound meters, each beat is divided into thirds. One of the most common examples of this is the use of triplets to add some compound meter to a piece that is mostly in a simple meter. Standard meters in Western music can be classified into simple meters and compound meters , as well as duple , triple , and quadruple meters. Duple, triple, and quadruple classifications result from the relationship between the counting pulse and the pulses that are slower than the counting pulse.

In other words, it is a question of grouping : how many beats occur in each bar. If counting-pulse beats group into twos, we have duple meter; groups of three, triple meter; groups of four, quadruple meter.

Conducting patterns are determined based on these classifications. Simple and compound classifications result from the relationship between the counting pulse and the pulses that are faster than the counting pulse.

Is a simple duple a 3 4? What type of meter is 3 4? How many beats does a quarter note make in 3 4? How do you calculate meter? How many beats occur in duple meter? Identifying Various Meters. How do you identify a compound meter?

How can you tell a duple from a triple meter? So, then some examples:. A simple quadruple metre would have four simple beats in each measure. What is a meter in poetry? What are simple time signatures?
