Depending on the camera model, the
preflashes precede the main flash by

main flash! The preflashes do not con-
tribute to the lighting of the shot.

digital TTL flash operation and a further
development of the TTL flash operati-
ons of analogue cameras.

rated into the flash exposure process.
The selection and/or setting of the pre-
flash TTL and ADI metering operating
modes are carried out on the camera
