Hello Folks, I just joined, and it looks like a good group. I will post an image this weekend.
I have the 6x12 multiformat, and I use it at 6x9. I'm afraid there would be too much drop-off of light at 6x12.
And I see some remarks about zero space between frames. I found a way to fix that. I use Kodak Tri-X, and I pay attention to what comes by the window when winding. For Tri-X, I think I see something like "Kodak Tri-x 1 Kodak Tri-X". So what I do is, instead of winding all the way to the 1, I stop at the first "i". And for the second frame, I go to the first "x"; then to the number, etc. I'm visually adjusting where the images go. And it basically works. I haven't lost anything yet on the first or last frame, which is the important thing. And I get some spacing, albeit small and uneven. After developing a roll of other film, save the paper and see if there is anything in between the numbers.
Cheers,
