Have you looked at the procedure for making glass emulsion plates or tintypes? you won't be doing that, you have neither the materials nor knowledge. Again, I am amused how people think something is within their abilities because "people were doing it 100 years ago". They imagine they could make a steam locomotive from blocks of steel; they imagine they could make a half-megawatt polyphase alternator from iron and copper.
If you're the only one left, I totally agree. However, if people were able to do it 100 years ago, then as a group, we can figure it out again. I'm not saying that I can personally accomplish all of these things, but we are human after all, and our greatest strength is adapting.
