I think it fair to assume that if you attempt to open shadows which are severely underexposed you'll eventually see "banding" or other digital artifacts. The solution is simply not attempting to "open" shadows this severely underexposed. (in my experience) You can always look for and find "the limits" on either extreme end; both highlight overexposure and shadow underexposure Regards, George Lottermoser http://www.imagist.com http://www.imagist.com/blog http://www.linkedin.com/in/imagist
