Rev Graphics Gurus

Dar, An old thread, and I hope you don't mind me contacting you directly. I asked a while back about presenting the average of two images, and you suggested that I a) group them, b) set the ink property of each, including the group, to blendSrcOver, and c) then set the opacity 0% and

Point 1; I am not a Graphic Guru (nor any other type of Guru!). Point 2; as usual I went for the naive route: Thought I would just have a bash at changing RGB values imported my image renamed it to a standard name PIC put the colors of image PIC into field F1 (there are a number of fields:
