I am having problems with the image shown here and my "Canaveral Sunrise" image in the Landscape Forum (http://www.birdphotographers.net/for...ad.php?t=11282) with Posterization or Banding.
It is occurring when I make a levels adjustment. I know this can happen in 8-bit more easily; I am working 16-bit. Interested in suggestions as to the cause. Thanks.
