Abstract
An apparatus and method for developing both black and white and color photographic film using a spirally wound tube. Each convolution of the tube is adapted to contain a selected film treating fluid agent. The film to be photographically processed is attached to a carrier having a magnetic element mounted thereon. The carrier with the trailing film is inserted into the spirally wound tube. A conveyor belt having magnets attached thereto is disposed adjacent the inner circumference of the outer surface of the convolutions of the tube. The film is processed by the carrier being magnetically guided by the magnet on the conveyor belt through the sequence of the different film treating fluid agents in the convolutions of the tube.
