Shooting in a Different Flash Mode for Each Group
When using an EOS DIGITAL camera released in and after 2012, you can shoot in a different flash mode set for each firing group with up to 5 groups (A, B, C, D, and E).
The flash modes that can be set are (1) E-TTL II / E-TTL autoflash, (2) manual flash, and (3) auto external flash metering. When the flash mode is (1) or (3), exposure is controlled to result in standard exposure for the main subject as a single group.
