I never taped my Aaton 35 III magazines and never got any leaks. Now every-time I see BTS images of film shoots the magazines are always taped - even Panavision mags..
Is this standard procedure for film loaders as an extra precaution for light leaks or is it for stock identification?
I'm shooting a project tomorrow and I just taped my 3 mags all around, between the doors just to be sure.
