120 film inside out on takeback spool? Mamiya 645 pro

valfreyja · Mar 28, 2015

Hi there,
I am new to medium format shooting and have just started experimenting with a Mamiya 645 pro. After successfully shooting and processing film yesterday I've encountered a new problem today. When advancing my film all the way to the take back spool to unload and process it the film seems to have been inverted. That is only the black paper on the outside shows and the exposed label with the tab are backwards. What could have happened? I loaded it the same way I did for the successful roll (the right way) and did all the same things to advance it all the way when finished.

Thanks!

Film was loaded incorrectly. Inside out.

Well, just for an alternate take on this, I once had a roll of GP3 that was rolled "inside out" ... it isn't beyond the bounds of possibility the OP encountered the same, so it'd be nice to know which brand of film he was using.

Welcome to APUG.

There is a small diagram on each film insert which show you how the feed spool and roll should be oriented, and an arrow on the takeup side that shows you the direction that the takeup spool rotates.

Most likely, you reversed the orientation of the feed roll, so the film ended up against the pressure plate, rather than the backing paper.

You certainly aren't the first to make this mistake, but most likely, you won't do so again.

me too

Your not alone- I did the same thing last week, first time loading my GF's Hassy 500Cshe's still laughing

You could re-spool it in the dark and use it for testing or something but its probably all scratched up, the emulsion was dragged across the back plate.

It has to look backward to be correct.

Develop the film.... that will be the answer.

No images? Film loaded backward and back of paper was 'exposed' to light.

Images come out correct? Something's royally screwed up.
