ABSTRACT:
Embodiments of the disclosed technology are designed for creation of a photographic image comprising an upper and lower portion from two rolls of film whereby the picture is created by simultaneous exposure within a single camera housing, or emulation thereof. This is accomplished in one embodiment by wrapping two rolls of film around a spool, one above the other, such that the rolls pull off the reel in parallel and onto a single take-up spool. Thus, when the shutter opens, both rolls of film are simultaneously exposed, and an image forms half on one and half on the other. In another embodiment, a camera comprises two film chambers (which may be a single chamber with divider adapting the chamber to hold two rolls of film), one above the other, and a roll is loaded into each film chamber. Embodiments may be used to breathe new life into discontinued film formats, such as 70 mm film cameras by using two 35 mm rolls of film.
