Yep, a rare sight to see young people going into alternative photography. This is partly because of stupid rules made up by people who know squat about chemicals makes it harder and harder to get the chemicals needed to do them. Other reason might be the limited knowledge about the old ways of photography. We have a Museum of photography in Belgium and even there very little info can be obtained about old processes. They have old process photographs and they are often called, "salt print of this", "Van Dyck Brown of that" but besides the names of the processes not much ohter info is provided about them. A real shame this is.
A rare sight? That depends on where you live. Where I come from, it's as rare as the beginning of each semester.
