Abstract
A photographic filmstrip is initially coiled about a spool inside a cartridge with a trailing film end portion secured to the spool and a leading film end portion being free. The filmstrip is advanced, leading film end portion first, from the supply cartridge into a host container such that the filmstrip is reverse coiled in the host container to reduce any longitudinal curl in the filmstrip resulting from the filmstrip being wound on the spool. The trailing film end portion is released from the spool. The film in the host container can be heated to further reduce the longitudinal curl in the filmstrip.
