Starting up a personal research-project on wet-plate these days, need to get the book first, then read, then figure out where to get the chemicals, after that, the materials (plates) and after that, the actual photographic equipment.

My impression is that wet/dry-plate is gaining popularity, specially for portraits etc (for potential buyers and clients).
A lot of the photographers I know, would like to try it out, but the biggest issue is getting hold of the chemicals in these days of "war on terror" in every country in the western hemisphere. :/
