What causes banding in digital images? I frequently find magenta and cyan banding in the skies and sometimes other places. Is there a way to avoid it? Is there any software that does a good job of removing it?
This image was taken with a Nikon D 850, iso-31, F 18, 24-120 mm at roughly 100 mm, 50th of the second, tripod.
The raw file does not look a whole lot different other than that it is in color. I will include it just for comparison sake.
Yes it was very foggy and I realize that diffraction from the fog can cause this. I converted this one to black-and-white primarily because I could not remove the colors regardless of trying to desaturate the individual banded colors. I have tried using Topaz De noise 6 and the feature to remove banding but it does nothing to work very well. I would sure like to hear some good suggestions about this.
