6x9 Voigtländer Bessa: which red window to use
My Voigländer Bessa 6x9 folding camera has two red windows1 on the back for looking up at what frame number you are and to know how far to advance the film for the next frame. I was wondering which one to use and found a photo.net thread on this topic. Here’s what I think is a correct answer:
> The second red window was for the 645 mask. You may use either red window so long as, on a given roll of film, you use the same red window consistently.
For my first roll, I chose the one on the left, which is the window further away from the take-up spool. Everything went well, with all exposures captured completely.

They’re actually orange in my case. ↩︎
