TTL: Auto Flash
In TTL Mode the flash and camera will work together to calculate the correct
exposure. When the Shutter Button is fully pressed the flash will fire a pre-
flash that the camera will use to calculate exposure and flash power the instant
before the photo is taken.
Flash Exposure Compensation (FEC)
The Juno TTL Flash allows Flash Exposure Compensation (FEC) adjustment from
-3 to +3 in 1/3rd stops. This is useful in situations where fine-tuning of the TTL
system is needed based on the environment.
