Camera has system for recording photographic factor on exposed image field of photographic film, records current factor on film if factors coincide, otherwise warning message
The camera has a setting system that sets a factor data item representing correct exposure, a measurement system that measures a current factor corresponding to the set factor during a photographic operation, a test system that tests whether the factors coincide and a recording system that records the current factor s on an exposed image field on the film if coincidence is achieved and records a warning message if coincidence is not achieved.
