How to set wireless multi-flash ETTL automatic flash with A:B Ratio control

Solution

Setting the A:B Flash Ratio

The flash ratio between receiver A and receiver B can be set to specify the main flash and fill flash. The flash ration can be set from 8:1 to 1 and from 1 to 1:8 in half-stop increments. In terms of exposure stops, it ranges from 3:1 to 1 and from 1 to 1:3. When the flash ratio is set, E-TTL autoflash metering controls the flash output to obtain a correct exposure.
Check that the ST-E2's main switch is set to ON then press the <RATIO> button
  • The flash ratio control lamp lights in red and the respective flash ratio indicator lights. The flash ratio for the unmarked indicators are shown in parentheses below
