I have now perfected my "tight arse" color grain specific cleaning actions and the newest version set is found right here: http://www.dpreview.com/... .../_ht_a/coolato/colorgraincleaners.atn
The bad news is..I believe the newest and best version may only be compatible with PS6...unlike the last one I posted (created in PS 5.5) ?

I was EXTREMELY anal in creating these so that they would offer the best compromise between preservation of color detail and removal of color noise/oversaturated pixels. It is very unlikely that one would find a better automatic method for removing color blemises that also preserves as much image detail as possible. These will hopefully prove that straight PS with a little dexterity (very anal, obsessive, compulsiveness) is dominant over expensive freeware and plugin software that perform similar (not as good)grain removal specific fixes. I've already compared my actions to some of these other software/programs and am convinced mine don't destroy as much detai (bleed colors left and right over edges)l, yet they still take out noticeable and unsightly color grain just as good.

Comments welcome....perhaps care for zoomed in before and after examples?

Note: the "heavy action" now preserves details significantly better than the last posted set...so you don't have to be too wary when using it...
