Only 28 Af-3 N Digital: I-Ttl And I-Ttl-Bl Flash Modes - Metz MECABLITZ 28 AF-3 digital Manual De Instrucciones

TTL-preflash metering
The TTL flash mode with preflash metering is an
advanced variant of the "normal" TTL flash mode.
Prior to shooting, the reflection of the subject is
measured with a preflash. The camera evaluates
the reflected preflash light so that the subsequent
flash exposure is optimally adapted to the pre-
vailing photographic situation (see operating
instructions of your camera).
Settings and displays
The flash unit must be switched to "TTL" mode
(see 4.1). On the camera, the flash mode "TTL
preflash metering" must be set (see operating in-
structions of the camera).
There is no indication for TTL preflash metering on
the flash unit's display.
ADI flash metering (Advanced Distance Integration)
ADI flash metering is a TTL preflash metering mode (see
above) that has been additionally extended by guide
number control. In this mode the camera additionally
takes into account the data relating to the subject's dis-
tance (see operating instructions of the camera).

i-TTL and i-TTL-BL flash modes
These flash modes are only available with
appropriate Nikon SLR cameras (e.g. Nikon
D70; see operating instructions of the ca-
mera)!
i -TTL flash mode
i-TTL flash mode is an advanced variant of the
"normal" TTL flash mode. When shooting a picture,
several weakly visible preflashes are fired by the
flash unit prior to exposure. The camera then eva-
luates the reflected preflash light so that the subse-
quent flash exposure is optimally adapted to the
prevailing photographic situation (see operating
instructions of the camera).
