A contact sheet is a photographic term for a set of prints exposed on a single sheet of paper. A photographer creates a contact sheet by laying strips of negatives on a sheet of emulsified photo paper and exposing it to light in a darkroom. This produces positive images the same physical size as the negatives. Approximately 30-36 images of 35mm film can fit on a single 8" × 10" contact sheet. Since looking at processed negatives can be a chore, the contact sheet can be stored with the negatives and used to reference specific photos quickly.
