Rough scans of collodion dry plates taken at the Yucatan workshop held by Scully and Osterman. These kinds of plates have very high resolution and a lot of Dmax, so are a bit tough to scan properly. When printed with a process they were intended to be used with (e.g., salted paper printing) a lot of the artifacts (e.g., fibers that landed in the varnish while it was drying) will not show up. They will, however show up here. First shot of the day in Uxmal. This was a bit of a challenge, as there was a strong, gusty breeze in addition to the intense sunlight creating a lot of contrast with the recesses in the building. We had the dark cloth over the back of the camera in order to protect the plate holder from the direct sunlight, but the wind kept turning it into a sail, which vibrated the camera considerably. Fortunately it's a very slow process, so as long as the camera returned to its initial position after a gust, things mostly worked out. Still a bit of effect, I think. In addition, this plate had some coating flaws; in particular the flare seen on the left hand edge was a bit of silver contamination on the plate. We couldn't figure out where it came from, although I have some unsupported theories. Just a thing that happens in a busy darkroom when a lot of people are working to get their plates prepared. The crud at the top of the plate was caused by the dipper when lowering the plate into the silver tank; for some reason, they stuck a bit to the collodion and scrubbed a bit of it off. Probably I wasn't paying close enough attention to it when extracting the plate from the dipper.
