Nikon D3 Tips, Tricks and Camera Settings
Banding?
You might have heard about high-ISO D3 images having a banding problem.
Stany’s post illustrates that this is a non-issue, as it crops up only when you shoot photos with two stops of underexposure over ISO 3200 with strong highlights in the image, and you recover that photo in the post-prcessing stage.
On the other hand, if you suspect that your camera is exhibiting the problem under normal conditions, consider having Nikon check your camera.
