I've been debating the idea of trying to do some alternative processone of these months/years, and based on what I've read the Van Dyke or kallitype seems like the one to try. I like the color control with kallitype, so thats in the lead. But thanks to a long, rich family history of cancer and general klutziness on my part, I refuse to mess with known carcinogens like those used for contrast control in kallitype. Minor chemical burns, I can probably live with. I'm not going to change my mind, so lets avoid that debate. Based on my limited understanding, that leaves me either needing to make digital negatives so that I can control the contrast, or making perfect negatives. The former probably isnt going to happen anytime soon even if I wanted it to, so I think that leaves only perfect negatives. So how hard is it to achieve that goal? I realize it will restrict my subject matter somewhat, but if I overdevelop contrasty scenes can I get consistantly suitable negatives for kallitype that dont need chemical contrast control?
