ABSTRACT
Today’s roll films, both 35mm and medium format, are marked with the manufacturer’s name, the product name, and the frame numbers. The pre-exposed frame numbers don’t always perfectly match the frames we are exposing, but they still allow us to correlate our exposure records with each individual frame on the roll. This is a service too easily taken for granted, and the benefits of it did not become apparent to me, until I exposed and developed my first sheet film.
