ABSTRACT:
A system and method for recording successive images of the same object at varying depths of field. An automatic distance measuring circuit measures the distance from an object, and a brightness measuring circuit measures the ambient brightness around the object. A shutter release switch is activated in first and second steps. A microcontroller controls the system and is connected to the automatic distance measuring circuit, the brightness measuring circuit, a shutter actuator, a diaphragm actuator, and a film motor actuator. After pressing the shutter release button once, a plurality of images are automatically recorded, each having the same exposure and a different depth of field.
