2.2. Flash exposure compensation (FEC)

Examine your photo. Is the area lit by the flash too dark or too bright? The output level of the flash unit is determined by the camera's automatic flash metering system, but it isn't capable of making artistic decisions.

To make the output of the flash brighter, press the SEL/SET button on the back of the 430EX II. When the symbol starts blinking on the screen, press the − or the + button. This is one way of applying more or less flash output, a feature known as flash exposure compensation (FEC) (sections 6.17 and 9.9). Adjust to taste. In the example shown here, the flash has FEC dialed down by 2/3 of a stop. Figure 2-7
