ABSTRACT:
A camera system and method for operation of fill flash photography, combining natural and flash light, which centers the times of natural light and flash light images. Synchronization is achieved by centering the time a flash is triggered midway between the opening front curtain and closing rear curtain of the shutter. In a particular preferred embodiment, a digital camera is coupled to a computer forming a system which stores images for image processing. The system includes a means for determining a period during which the shutter of the camera system will be opened and a means to determine a middle period in the the open shutter period. Preferably, the flash is fired at the midway point of the shutter period. This midway point in time is used to trigger the flash so it is substantially centered in time within the shutter period.
