NO, that's just the naturally occuring Canon RGB noise in shadow areas I always get. For some reason they seem to be a little more exagerated on the J. I didn't use S/H, just isolated and used selective H/S. I can bring the levels up a litttle more on the underside. I'll work on it some more. Hey, at least it wasn't black! :)
Ok, I went in and isolated the white area (top & bottom) went to selective colors, removed R,G,B,N (gray) and a little black then increased white levels in levels. :o
