I've been thinking about trying the Panalure also. I almost bought some on ebay, but was scared off when the seller told me that it is not variable contrast paper. Can anyone confirm that?
I print some color stuff on b & w paper once in awhile. Sometimes I get that great photo when I have color film in the camera instead of b&w, but I want to be able to play with it. I think I used a grade 1 or 2 filter to try and even out some of the oddities. I have about 45 rolls of color negs from a Europe trip in the late 90's that I'm planning on going back to and playing with some day. I did a coupld shots and they came out prety cool. I think you probably could pick them apart from true b&w negs if you really were into it, but then again, they can look good anyway.
