Yeah, I'm thinking the old metal boxes. I had a feeling that it would work reasonably well for alt process stuff (and I have all the chemicals I need for salt printing at the's just waiting to be mixed up), but I don't really think that using it for silver printing would work. I thought about it last night while trying to get to sleep (as I often do) and figured out that it would only really be useful for straight prints. If I wanted to do any sort of dodging or burning I'd be better off with the Weston bare bulb method.
