This comparison regrettably had a change in lighting—the images were taken at dusk, and the floodlights switched on between cameras. This will have little effect on resolution however, which is the point of this particular comparison.
The idea here is simply to show how much more detail the D3x can resolve compared to the D3. Nothing fancy—a Photoshop bicubic upsampling was done to match size once the images had both been processed through capture NX 2. The same lens, the Zeiss ZF 100mm f/2 Makro-Planar was used, at f/5.6, with the usual tripod/mirror lockup/remote release that I always employ. The D3x used an “L” bracket and the D3 a bottom plate, so the images vary slightly in rotation.
The light for this comparison was very flat and blue, and processing was done at 9000°K for the D3x image and 8000°K for the D3 image (due to the warming floodlights).
