I don't know what to call the kind of back my 4x5 camera has but its a spring loaded hinged arrangement to slide in the film holder. I believe this is common. The camera is a Toho camera the same model as this image of the back from KerryThalmanns site.
I'm interested in using a roll film back with the camera and because most of these are made for operation with a grafloc back. Now my camera does not have that so I'm down to sliding it under the flap (can someone help me out here and tell me what this sort of arrangement is called please?)
I'm seriously thinking of considering making a custom back for the camera (that screws into the same mounting holes) to allow for the detachable glass and attachment of these types of roll film holders.
BUT ... due to living in the middle of nowhere I don't really have any access to seeing a grafloc back to get an idea of how it works and what dimensions it has.
So, if anyone has a camera which has this kind of back and wouldn't mind perhaps popping it (back down) onto their flat bed scanner (with a ruler) I'd be really appreciative. I think this would help me with sorting this issue out.
Perhaps its not possible?
