Automatic metering and registration, between exposures, relative to an exposure station in a still camera of a next available unexposed frame of a perforationless filmstrip is achieved by reading frame number identifying cues, including stop point flags, magnetically encoded on the film. Continuation of registration is confirmed and, if necessary, corrected automatically in preparation for the next exposure by reading the same cues and comparing a stored cue for a desired next frame with a cue read from a registered unknown frame. The direction of film movement for misalignment correction is set based on the frame number comparison.
