Hi All-- This may seem like a strange request, but I'm hoping someone out there can help me out. Where can I find a fairly cheap shutter? Something with maybe just 1 or 2 speeds in the 1/10 to 1/100 range and a T or B setting? Leaf shutter preferred, as I think it would be easier to adapt than an FP shutter. Clear opening of about 25mm (or more). The shutter in a Kodak Medalist seems a likely candidate, but there's no way I'm going to cannibalize my Medalist for this. So I'm hoping that someone out there who's laid their hands on many more cameras than I might have a suggestion for some cheapy camera to buy that I can salvage the shutter from. Why? I'm playing around with the idea of a DIY sensitometer, which is, when you think about it, an incredibly simple instrument. In order to get the exposure times down out of the range of potential reciprocity failure in B&W films, I've decided that I'll use a continuous light source and a shutter, so I don't have to worry about warm-up and cool-down of the lamp. I know this may seem impractical, but I like experimenting, so humor me? Thanks in advance for any help. --Greg PS-I'm also considering a gravity shutter, but I want to pursue both avenues if possible.
