My guess would be less than 1000 worldwide making plates on a regular (or seasonal) basis. I think a lot of the members of both collodion forums haven't picked it up yet. Mosts of the posts are made by the same core group so there are a lot of lurkers who don't practice the process yet. Maybe 30-40 folks show up at John Coffer's annual Tintype Jamboree. He's holding 6 or so workshops/year with 4 in each workshop. Then there's the Ostermans, Will Dunniway, Eric Taubman, Kerik, Michael Mazzeo, Quinn Jacobson and few others holding workshops on a less regular basis. So, the ranks aren't growing too fast though there has been an acceleration lately.
In Michigan, I know of myself and 5 others who currently make plates, and 2 retired from it. I'd bet there are more, but I don't know how many or where they are in the state.
