Abstract
Abstract A method and apparatus that exposes any desired length of film, develops it, and makes it available for use while allowing for continued exposure of further film sections is disclosed. These sections of exposed film are delivered to a processing portion of the apparatus by use of a turret arrangement having two collection magazines, wherein the turret is rotatable to deliver exposed film to the developing section. The exposed film is developed in a series of cascading baths and thereafter fed to a collecting magazine mounted on a rotatable turntable. Two such collecting magazines are attached to the turntable such that the turntable can be rotated and an individual magazine removed while the alternate magazine is put on line for receipt of subsequent film portions.
