Forgive this newbie question, but I made photograms of african masks. To
developer, I painted on developer of all strengths (I also used developer
that was meant for processing machines) with paint brushes of dif. sizes.
The result is that instead of a standard B&W photogram (with the mask being
white), the mask looks painted. The strokes are in every shade of gray
imaginable. I never knew there were so many grays. (The shades run from an
almost black-gray through a almost pure white)
Given this, and the "loss of gray tones" Carl spoke of, will imagesetter do
the job? I notice someone spoke about gray dots with Lightjet 5000. Would
this better? Or is all of this not at issue and not on point?
