Attached Link: Kort's Elfwood Rainbow image

Great discussion. I think Richard was right about the must haves. The rest are just for play and if you have a specific image in mind. I like adding effects afterwards - the control it provides. I had a rainbow filter for PS before I upgraded to the newer version...it didn't look overly realistic. The attached link shows you some of my old photomanips, this one with the rainbow. It is good for a laugh. :-)
