Very odd issue with a Hassy 500C/M and an NPC polaroid back
I'm currently experiencing a very strange issue:
I'm using a Hasselblad 500 C/M, an NPC polaroid back with Fuji FP-3000B, Pocketwizard TT1 and TT5 radios and Canon Speedlites.
I am fairly confident that I expose and meter properly, as this exposes correctly on roll film.
However; when using the polaback and the FP-3000B film, I get horribly underexposed shots. No idea why.
It's as if the flash isnt there at all. But this only happens with the polaroid film... Any thoughts?
Could the emulsion of the polaroid film be less suseptible to flash, or something (strange as it may sound)?
Realized this might be the wrong place for this, so if a mod would like to move this to the polaroid section that would be fine.
