Hello,
I would very much like to play a bit with 4x10 format... But all my film holders are 18x24cm and the resulting negative would be a bit narrower, so I'd like to buy one or two 8x10 holders and maybe a spare darkslide so that I'd have something to cut... I don't mind old (wooden) or battered ones, but they have to be light tight.

Thanks,

Andrej
