Tess, partial shade, f 5.6, 6 seconds, old workhorse collodion, black aluminum plate. The scratch is from a momentary catastrophic loss of coordination in my dinky dark box while putting plate into silver nitrate bath. The original plate is otherwise clean, I think the white specks etc are from the scanner.
I also did my first glass plate today, a portrait of my wife. It turned out reasonably well. Collodion lifting a little here and there around the edges, not sure why, maybe insufficient cleaning of glass before pouring.
