If so, what sorts of cameras use it? If not, why does this not exist?
I may consider making some myself if it doesn't exist, and would be interested in knowing what sorts of pitfalls or snags I might run into. Or if it exists, then it might be silly to make. Basically, I was considering one of two possible designs:
1) affix the commercially purchased loose sheet film somehow to a roll of durable, reusable plastic clear material, and leave a gap in every space, or every 3rd space or whatever, that can be used to focus on the ground glass. So you would take a photo, then roll it to the nearest empty spot, pull back a light shade, focus on the ground glass, pull the light shade back again, and roll to the next unexposed piece of film, then shoot.
2) Make a crude large format "SLR" but without bothering with a prism, of course. Just a fold down mirror, designed with nice velvet "gaskets" or similar so that in the down position, it completely blocks light from the film, and in the up position, it blocks any light coming in from the ground glass (which would be positioned on the top of the camera). Operated by a manual lever and locking mechanism built into the hinge. So you would take a photo, then lower the mirror (a light shade would be in place over the GG to prevent light getting in while the mirror is half lowered), pull back the light shade on the GG, focus and compose, pull the shade again, raise the mirror, roll the film to the next position, and shoot.
The only major issue I can anticipate with either system is that the film may not lie flat enough, but it could probably be made to pass through long guides on top and bottom as it rolls past to help with this.
What am I missing?
