9.1 Automatic fill-in flash

Some cameras offer the facility of activating auto- matic fill-in flash control or automatically trigger a fill-in flash. Fill-in flash will soften harsh shadows and diminish the contrast, thereby producing a more balanced exposure when shooting against the light. The camera’s computer-controlled measuring system automatically selects the shutter speed, working aperture and light output in such a manner that both the main subject in the foreground as well as the background are uniformly exposed.

Please refer to the camera’s operating instructions.
