Today I put up a few pages (and images) documenting the color issues we're having with Adaptive Contrast Enhancement. I should probably do some Real Reading, because I'm sure "change luminosity but not chromacity" is an operation done by millions on a daily basis. Hopefully, someone will at least point me in the right direction. Thanks to Ankh, garrett, and the NOAA for providing images for me to use. I think that next, I'm going to have to do some work with a nudibranch.
