Abstract
In the low cost APS camera, an exposure counter is originally at count 1 and is covered by a flag which is removed from count 1 when the shutter release button is depressed. When the film is returned to the cartridge and the exposure indicator is parked, the flag covers count max. The counter returns to the initial count position in response to opening the film door. The counter is incremented off the HEL (high energy lever) instead of the film perforations.
