For this comparison, a subject was chosen that exceeded the dynamic range of the D2X and D200 by a small am0unt. An exposure of f11 at 1/100 was chosen as the “correct” exposure [see large images: D2X, D200]. A setting of Tone=Low Contrast was used in Nikon Capture to process the images.
Histograms—f11 @ 1/100 second
The histograms from each processed 16-bit image are shown below. Note that both the D2X and D200 show highlight and shadow “clipping” (loss of detail). The D2X appears to have more clipped highlights, consistent with the findings on the Dynamic Range page, and the shadows appear slightly more clipped as well, though that’s harder to be sure of by looking at the histograms.

Highlight and shadow clipping
Nikon Capture offers a useful feature that shows clipped highlights and shadows.
Let’s first compare the clipped highlights.
In the images below, white indicates total clipping of the red, green and blue color channels, black indicates no clipping, and color indicates clipping of one or more channels.

|Nikon D2X @ f11, 1/100 sec clipped highlights|
Without a doubt, the D2X has clipped the highlights more than the D200.
Decreasing the exposure by 1/3 stop to 1/125 second now shows the D200 clipping nothing more than a few specular highlights, whereas the D2X still clips some significant areas (see below).
At 1/100 second, the D200 clips only a little more than D2X at 1/125.
In other words, the D200 is showing nearly 1/3 stop better dynamic range in the highlights than the D2X.

|Nikon D2X @ f11, 1/125 sec clipped highlights|
There is no doubt that the D2X has clipped the highlights more than the D200.
Clipped shadows are shown below. Here it’s harder to tell, but the larger amount of black in the D2X image reveals greater clipping of the shadows than with the D200.
Black indicates total clipping of the red, green and blue color channels, white indicates no clipping, and color indicates clipping of one or more channels.
|Nikon D200 @ f11, 1/100 sec clipped shadows|
|Nikon D2X @ f11, 1/100 sec clipped shadows|
The D2X has clipped the shadows more than the D200.
Decreasing the exposure by 1/3 stop to 1/125 second now shows the D200 clipping slightly more than at 1/100 second, but about the same as the D2X at 1/100 second.
In other words, the D200 is showing about 1/3 stop better performance in the shadow clipping.

A 1 stop “pull”
Taking the 1/60 second exposure (1 stop overexposed), let’s “pull” it in Nikon Capture. The results show that the D200 does indeed retain more highlight detail, though the D2X image still fares remarkably well. [Note also the increased sharpness of the D2X image; the D200 image was upsized to match.]

A 4/3 stop “push”
The 1/250 second exposure (4/3 stop underexposed) was “pushed” in Nikon Capture by 4/3 stop.
Although the D200 and D2X images were taken only a few minutes apart, that was sufficient time for the angle of the sun to change enough to make assessing the shadow areas more difficult than a fixed-lighting situation. Wind and leaf movement also mean the leaves are not in the same place in both images.
In general, the D200 image is more open with more natural-looking color, and the D2X image is murkier, with a slightly grainy and darker look, as would be expected when more dark values are pinned to black or near-black.

The D200 confirms its slightly greater dynamic range in this field shot, consistent with the slightly greater dynamic range seen in the studio shot. The D200 enjoys a bit less than 2/3 stop more dynamic range, perhaps 1/2 stop better performance.
Based on shooting both cameras over a period of time, this greater dynamic range can be described as also rendering a slightly “flat” (lower contrast) appearance when compared directly to D2X images, similar to the difference seen when comparing the D2X to the Canon EOS 1Ds Mark II, though not as pronounced.
