Film can

A film can is the light-tight container used to enclose film stock. They are typically a circular box pressed from thin sheet metal, but plastic examples are also used. Film cans are used to hold unexposed film, exposed film ready for developing and also for the distribution of completed film prints. The last of these does not require the can to be light-tight, but environmental protection and exclusion of dust makes a similar container just as useful.

Cans of undeveloped film must only be opened in darkness, within a darkroom.
