Hello,
I'm working on a project involving long exposure, but in several cases when there is a large portion of the image as sky, I'm getting a banding effect that renders the image unusable.
I'm using a Nikon D90, with long exposure noise reduction off, and shooting at base ISO. It doesn't look like standard noise or hot pixels, but rather swaths of uneven colour gradient:
260sec
Any advice would be greatly appreciated!
