Mamiya 645 Pro: my negatives are not centered

filmfan · 05-13-2012

So I have been shooting a KEH EX-grade Mamiya 645 Pro recently and noticed that the frame is positioned to the bottom of the film, giving uneven borders. This makes it difficult to center the image in my enlarger's negative holder, as well as IMPOSSIBLE to scan the entire image with my Epson scanner film-holders.
Any tips?

They're all like that. I have a 645 Super, which uses the same backs as the Pro (the Pro and Super backs look different outside but are fully interchangeable with each other). I have two backs for it and both do this. They're actually not consistent in where the image falls. On one roll it may be centered, the next it may be to one side and the next to the other. That's just the way the Mamiya 645 backs are.

Thanks for your expertise. I may try and carefully center the film-insert and see if that helps...
