I've never seen a sheet of 4in x 5in film sag in a glassless carrier, but I'm not so sure that an unsupported sheet wouldn't pop due to heat in a condenser enlarger. That's not a problem I'd expect from a scanner.
When you think about it, sheet film is barely supported in the film holder when an exposure is being made. I used a DeVere copy camera for several years and every exposure was tack-sharp even though, with the camera always vertical, the film was always horizontal and only held by the edges. regards, Anthony Farr ----- Original Message ----- From: "Bruce Dayton" <[EMAIL PROTECTED]> > You are correct about the carrier holding the neg above the glass. > Depending on the size of the negative, you can get some sag in the > middle.
