Abstract: Apparatus for reformating previously photographed data including a single light source and a mirror system for directing the light from the source in first and/or second mutually perpendicular axes which intersect at a point. Developed photographic roll film is advanced in a first plane past a first location which is spaced from the intersection point on one side thereof, the first axis passing through the first location and being perpendicular to the first plane. Developed photographic slides are positioned at a second location in a second plane perpendicular to the first plane, the second location being spaced from the intersection point on one side thereof and the second axis passing through the second location and being perpendicular to the second plane.
