Using film in wooden book-form plate-holders
I am sure this is a time-honoured question, and I have searched for previous posts on this topic.
I am about to begin using vintage half-plate and 10" x 12" wooden plate-holders with traditional modern black & white film stock. I have made surrogate glass plates from 2mm thick Foamalux (plastic board) and covered them with matt black vinyl. As you will know, the wooden rebate, which was originally designed for holding glass plate, is only a few millimetres deep. Obviously, my concern is that the film drops out when the sheath is withdrawn, or rather how to prevent this from happening. Has anyone surmounted this potential problem, and can you offer me any advice please?
