Blogging for Thor: Developing Developments

Day 7 of Exposure, Unsalted Silver Nitrate Print

I've currently put my "un-salt" prints on hold for a bit, but I'm sure that I'll be back to them soon. Part of that was finding out that the "cupric chloride" I got from Bostick & Sullivan was actually cuprous chloride. That little difference means quite a lot, since cuprous chloride is a fair bit more dangerous to work with than cupric chloride. It's also not water-soluble at all, so even if I wanted to risk it, I couldn't make a solution out of it. So, that sucked. I do still have several more chemicals, including cesium chloride, that I'm looking forward to testing out. For right now, though, I'm focusing on my actual prints instead of pure research.

What I've been doing lately is making scans of the prints as they develop. This means not only do I get to track the degredation of the print once it's made, I get to see what's happening as the exposure goes on. Since my exposures are upwards of two days, this works pretty well. I'm expecting this will go faster once there starts being brighter, hotter days again.

Overall, I'm enjoying getting a glimpse at the work from the other side. Normally I only get to see if out of the frame when it's finished exposing. I might lose some detail and registration this way (since I have to take the print out of the frame, remove the photogram object, then reassemble the thing after scanning) but I'm getting a lot more information. The process of development is really more fascinating than the process of print decay.
