An apparatus for automatically processing photographic film disks immerses the disks in a plurality of baths of treatment solutions one bath, after another, spins the disks about a horizontal axis of rotation during successive immersions to agitate the disks in the baths, and spins the disks between successive immersions to remove excess solution from the disks. A horizontally supported spindle is used to accumulate the disks for high density processing while a transport mechanism conveys the spindle between the baths and between first and second rotary drives to agitate and remove the excess solution from the disks respectively, in accordance with an appropiate processing sequence.
