TTL-Converter unique feature for M mode: Comfortable manual control for underwater strobe intensity using camera wheel and camera scale 1/64 to 1/1

The TTL circuit firmware has a special module, which allows the photographer to use three variants of M mode, including both the classic method and the advanced method. Advanced control allows the user to adjust underwater strobe light intensity manually via camera scale from 1/64 to 1/1 (Full). In this case, the photographer does not need to operate any dial switches on the strobe body but can keep his/her hands on the housing, switch to M mode and set flash intensity via camera controls allowing for comfortable shooting in M mode.
