TTV

I've never actually tried a TTV yet, so I thought I'd have a go whilst Ed had temporarily stopped asking for advice on alternative ways of phrasing stuff so that he could put it in the dissertation from hell.
I haven't yet constructed anything to exclude the light, so this is just a trial, but I think there is a lot of potential for some useful improvement. The setup for this is my little lumix looking down the hole of a Mamiya RB67. The polaroid back has been fitted, so when I remember how to do it, I'll also get some prints of future attempts.
