you could go to your local lab and make duratrans , dura clears, or inkjet masks as easy.
I like the idea of a colour material .. my thinking by making areas magenta or yelllow, or blue , green you could not only lighten darken but control contrast in areas.

Using the Lambda and making silver and colour prints via PS is where I am at these days.
The yellow/magenta thing is what Alan Ross is doing (in addition to the layered contour mapping you mentioned and pencil/dye shading) to essentially get straight prints out of Ansel's negatives (all burning and dodging and multiple contrasts built into the various layers of mylar and inkjet transparencies). For pencil shading and contours he uses Dura-lar, with a sheet of diffusing plexi.

You mentioned Duratrans. This is probably the best diffusing paper I've ever seen in terms of uniformity. I was wondering where you can currently buy this stuff. I bought a few sheets from Lynn Radeka recently because I ran out, but if you have a real source for this I'd be grateful to know. Does Kodak still make actual Duratrans?
