The AirTTL system

What is the AirTTL system?
TTL is when the flash exposure is set automatically by the camera instantly communicating to the Air Remote how much light is needed. The Air Remote will in turn wirelessly communicate the correct exposure settings to all lights. Perfect for situations where you need to act quickly to get the shot.
