i hate cutting negatives ... 6x6, 6x9, 1/2 frame, 35mm
its a pain .. but i use old scissors stolen from my mothers sewing basket
and a newer pair of scissors i found a few years ago they just ended up in the darkrom.
i just hold the film to the light, and cut .. its not really rocket science .. and if i screw-up, oh well ..
thats a great reason for shooting sheet film, you don't have to cut the negatives, unless you are
shooting split frame ...
