If the problem is aliasing, you can prove it by taking a defocussed shot. If it goes away when defocussed, it was aliasing. ----- Original Message ----- From: "Tim Vitale" <tjvitale@ix.netcom.com> To: "Rene Damkot" <rene@damkot.com> Cc: "ColorSync User List List" <colorsync-users@lists.apple.com> Sent: Tuesday, May 8, 2012 5:13:04 PM Subject: RE: I suspect the original art pigments along with the 1Ds Mark IIsensor is part of the issue. What do you think? Just spit balling... Your using a Bayer pattern camera. Could this be a moiré or color aliasing issue? Have you checked at the very highest resolution in PS? Check <dpreview.com> for a very nice explanation of color aliasing. I have had many printing issues using inkjets, where the "dot pattern" was the issue. Inkjets must have dot patterns afterall. Some RIPs offer dot pattern options, or at least offer their take on the pattern process. I happen to like Epson's technique and just work around it. My solution was solved by adjusting the color balance to produce the color I wanted to see. In my case it was tweaking the magenta/green and yellow/blue sliders in <Color Balance>. You may have to select the area and treat it differently from the rest. ICC profiles can't solve everything, and actually cause many problem, generally they cause fewer problems than they correct. Have you tried a BetterLight scanback or a Sigma [SD1 Merrill] body for the image capture, neither uses the Bayer pattern. If you like, see if you can get Mike Collette [of BetterLight at mike@betterlight.com] to comment on your findings. He is a very critical thinker and knows how to make sand look right <http://www.betterlight.com/gallery/index.html>.
