I just got a used grafmatic holder and did a test shoot today. all 6 sheets suffer from light leaks of some kind. I wonder is it due to operator problem or it is the holder problem?
The 1st 2 sheets are better but the area where the notch is suffer from light leaks
for eg (photos has been crop to reduce size) :
the other 4 sheets suffers from a band of light leaks at the notch end:
any advise? thanks.
