it sure is. That panchromatic paper is very interesting stuff. With tame developer, the speed is slow, but I'm getting super high peed/solarization effects with powerful developers...to my surprise. It seems to be an "overdevelopment" type of thing going on or something. I still haven't found the high point of the high speed--but I'm running out of paper to play with. Where I want to be is using the high strength developer with normal speeds and no solarization--so I can have direct reversals with paper at a decent speed. that's what the hope is now.
