Hello there, I have a question I’ve also posted on the British LF forum:

Here in Berlin, I have the opportunity to use a Hasselblad X1 scanner for a very reasonable price. Unfortunately, the film holders I can use are all of the prefabricated, default kind. The 4x5” ones are 94x119mm, which doesn’t allow for the whole image surface to be included in the scan.

Does anyone on the Forum have practical experience (or know about someone) using custom-made film holders with sheet film? In particular my question is whether or not the contact surface of a holder of, say, 97x121 or 97x122mm is sufficient to firmly hold a 4x5” sheet in the holder while it bends inside the scanner?
