Modify your 6x9 mask to be able to take 8 larger pictures on your 120 film.
Did you notice that the *Belair X 6-12* isn’t really a 6×12 camera? The dimensions of the “6×12” mask are actually 52mm x 104mm. The masks with the “6×6” and “6×9” ratios have the same height and consequently measure 52mm x 52mm and 52mm x 78mm.
A 120 film can contain 12, 8 or 6 exposures with the respective sizes: 60mm x 60mm, 60mm x 90mm and 60mm x 120mm. So taking pictures with these smaller masks leaves some unused film.
We can’t enlarge the camera so we’re stuck with this 52mm height and maximum 104mm width. But we can modify the 6×9 mask so it has a whole 90mm width. This way, we will still be able to take 8 exposures with this mask but the pictures will be larger, almost as panoramic as with the 6×12 ratio. The picture at the beginning of this tipster is taken with this modified 6×9 mask.
The following picture shows two unmodified “6×9” and “6×12” masks, and between them my custom mask. I used a razor saw and a modelling knife to cut the extra plastic.
Here we can see how thin the gap is between the two pictures taken with this mask.
Finally, some other examples, this time in portrait orientation.
