A photographic film strip in the form of a length of photographic film has a pre-exposed area and an unexposed area. The pre-exposed area is continuous and extends along one edge of the strip between ends of the strip. The unexposed area is also continuous and has a length suitable for making multiple single exposure frames with adjacent frames being separated by a frame line. Upon development the film, an image formed by the pre-exposed section of each print will extend between opposite edges of prints formed by individual frames without the need to preregister the film in a camera The pre-exposure comprises a contact exposure. A strip of film can be placed in contact with a partially pre-exposed master on a cylindrical drum in a light tight housing so that pre-exposed section of the film can be exposed by one activation of an electronic flash located in the center of the drum.
