The market makes us see things we would not see (or perhaps choose) for ourselves. In my case, buyers are not emptying my stall at occasional art shows. But many lookers ask if I can do "old timey portraits," imagining a quick sepia polaroid shot of themselves in quickly-chosen period costumes. My interpretation is that I can offer period-correct photo sessions for tintype pictures made at the visit and picked up later in the day (or by mail) using dry plate tintypes for now.
To try out the process, I purchased the subject Rockland Colloid Tintype Parlor Kit, which for about $36 will produce up to 8 4x5 tintypes. Yeah, the cost of goods starts at about $5 a plate for the joy of getting sticky and expecting uncertain results. But we do this for fun before profit, right?
My first plate surprised me by actually bearing an image, despite my having dropped it face-down on the floor while failing at "the waiter" holding technique for coating it. The dry gelatin process is messy and follows entropy better than any other process I know of. But I'll have fun with the 8 plates (with maybe enough to coat a glass lantern slide for my old Kodaks). I'll add other results as I get to them... this may take time.
Here's number 1, made with a homemade sliding box camera fronted by a 9" f/4 Petzval portrait lens. I don't understand the green or blue, but suspect fixing time might be a factor. But it is a happily interesting effect.
