I an thinking of trying some alternate type of paper. I am looking at Cyanotype, Platinum, Kallitype ... and a bunch of others. What I shoot is landscapes and portraits. I would like to try something that: gives rich mid-tones isn't terribly expensive isn't terribly difficult isn't terribly dangerous The kits on Photoformulary look appealing but I don't know enough to make a choice and try one. I will be using 4x5 as my choice format. I am happy to make an enlarged negative for a contact print (8x10 on a 11x14 sheet?). So I am looking for someone who has experience with several of these and can point me to a favorite.
