Yes, I've heard of cyanotypes, Van Dyke prints, platinum, palladium ,etc..but regrettably I've never tried my hand at making one. I don't print much, perhaps just once a month, and even then it'll just be making prints of 1 or 2 negatives. I'm more interested in an alternative to gelatin in the image capture process, instead of in the printing stage. Perhaps it's time to try wet plate collodion?
