ABSTRACT:
A camera capable of identifying photographing conditions causative of red-eye effect making the eyes of human pictures in a flash-photographed picture come out red, and recording the identified photographing conditions in an external memory provided on a film cartridge loaded thereon. The camera recognizes the possibility of occurrence of red-eye effect on the basis of the focal length of the camera lens, the object distance, the distance between the optical axis of the camera lens and the light source of the flash light device and the object brightness. When the photographing conditions are identified to be causative of red-eye effect, a warning is displayed and flash photographing is forbidden. When photographing operation is carried out under photographing conditions liable to cause red-eye effect, information about the exposed film including the photographing conditions is recorded in the external memory to enable the subsequent developing and printing processes to correct the photograph with reference to the information.
