Using the Flash

Red-eye Reduction

As with the built-in flash, the red-eye reduction function is available with an external flash. The red-eye reduction function works by discharging the flash twice even when only an external flash is used. However, this function may not be available on some flashes or may have restrictions for usage conditions. Refer to the chart on p.211.
