Could somebody tell me what the exact dimensions (in milimetres) of 5x7 film are? I have 13x18 film holders and I am wondering if I can use 5x7 film in them. I use exclusively 13x18 Delta 100 which is readily available in Europe
( I live in Greece and buy my film in Germany ) but some times I really feel
the need for a 400 film and the only option available seems to be 5x7 HP5.
