The roll film may come with or without perforations, sound track, leader, and/or trailer. The sheet film may be cut in sizes that can be easily handled one sheet at a time, or prepared in pack form where a quantity of sheets are enclosed in a pocket so designed that individual exposures can be made by removing tabbed shields.
