Matrix Balanced Fill-Flash

With the system set to Matrix, Matrix Balanced Fill-Flash is avai lable.

Based on a combination of general scene brightness and con- trast, the exposure value for the background is determined by one of five computation methods: Low-Brightness Weighted, Center-Segment, Average, High-Brightness Weighted, or Very- High-Brightness Weighted. Together with the background exposure metering, the F4'smicrocomputer automatically chooses one from five flash output levels determined by the combination of brightness and degree of contrast. The result is a balanced combination of ambient light and flash il lumination that produces a natural-looking and pleasing effect.

Center-Weighted Fill-Flash

For regular TIL flash photography, or to emphasize detailed background areas, use Center-Weighted Fill-Flash. In this mode, when the value measured by the center segment is within the controlled shutter speed/aperture range, flash output compensation is automatically set for natural -looki ng fill-flash photography. (If the value is less than that of the controlled range, standard TIL flash without compensation is selected.)
