Please, explain dynamic randge, and compare it D700 Vs. D200. Thanks, Sam
Simple answer is no one knows at present. Ask again in about 4 weeks, assuming camera is released when we all think it is, end of July. I would GUESS that being a FF chip, it would have better dynamic range, but until it is in actual use, the amount it is better is anyone's guess....
http://en.wikipedia.org/wiki/High_dynamic_range_imaging More is better.
Here is the info for the DR of the D200: http://www.dpreview.com/reviews/NikonD200/page22.asp Haven't seen it for the D700 yet, understandably.
If , as appears to be the case, the D700 is using the same internal image pipeline as the D3, in 14 bit per channel NEF mode you'll have about 12 stops of real dynamic range with the D700. My best guess withthe D200 is that the dynamic range is closer to aboput 10 stops. Dynamoic range is the measure of the sensor (or film + developer's, or paper's) ability to record tones from absolute black to absolute white . Actually absolute black and absolute white are easy so what we really mean by dynamic range is how much real world detail can be seen in the areas just above absolute black and just below absolute white. The larger the dynamic range the greater the ability to see those differences ("Difference is detail" --Bruce Fraser). Mostly where we we see the benefits of large dynamic range is up in the ability to record detail up in the bright highlights. The big idea is that you want to start the capture-t o-final form (print or web based) process with as much usable information as possible.
If you like to see how it looks on a real shot (in this case D200 vs S5), check it here.
Link provided by Todd, the DPREVIEW, shows Canon 5D has the same "usable range" DR as D200, and they differ a lot in size of pixels, perhaps as much as D200 and D700 ? Possibly D700 will have better DR, but the usable portion of it could be ?
If you want high dynamic range, get a Fuji S2, S3 or S5. They all beat any Nikon SLR.
basically, the D700 is a D3 in a D300 body. so it will have the same DR differences as D3 and D200. i'd go with Ellis' estimate of a two-stop gap in real-world terms. but if DR is all you care about, get a S5 or a Sigma DP14/DP1. if you want the total package and ultimate versatility, go with nikon.
Jose - who asked about the Fuji S5? Besides, your test looks seriosly flawed because you've clearly under exposed the D200 shot.
Jose, do you take both cameras at same time with same lens? It looks like -1.0 to -1.5 on D200.
If the Nikon shot was brought up to the level of the fuji, the highlights would be way blown. I would like to see a comparison of a 14 bit camera thrown into the mix.
14 bit will get you better shadow detail, but won't help the highlights.
Ooops, I didn`t made this test. I added the link -only- for illustrative purposes. I have already noticed that the page is not signed... definitely it`s not mine. Looks like it belong to a Scottish wedding pro site. Please excuse me if it looks the opposite. Anyway, looking at histogram I understand it could be valid. The exposure looks to be based on highlight areas, thought, and clearly the D200 shows its limit on shadowed areas. It can be easily understandable due to the specific design of Fuji sensors to avoid blown highlights. Wei, it also looks that the photographer used the same lens on both, althought the camera was slighty turned on the second shot.
