Preflash Ttl And Adi Metering; Manual Flash Mode - Metz Mecablitz 64 AF-1 digital -Sony Bedienungsanleitung

7.2 Preflash TTL and ADI metering

Preflash TTL and ADI metering are digital TTL
flash operating modes and refined versions
of the TTL flash operation found in analogue
cameras. When taking a shot, an almost
imperceptible measurement preflash is trig-
gered by the camera prior to the actual expo-
sure process. The reflected light of the mea-
surement preflash is evaluated by the
camera. Depending on the result of the eva-
luation, the subsequent flash exposure is
adapted by the camera to suit the given shot
situation (see camera operating instructions
for further details). In the case of ADI mete-
ring, additional distance data from the lens is
incorporated into the flash exposure process.
The selection and/or setting of the preflash
TTL and ADI metering operating modes are
carried out on the camera (see camera opera-
ting instructions).
The flash unit must be set to the
operating mode.

7.3 Manual flash mode

In the manual flash mode M, the flash unit
emits the full uncontrolled amount of light if
no partial light output has been selected. The
specific photographic situation can be taken
into account by adjusting the aperture set-
ting or by selecting a suitable manual partial
light setting.
The setting area ranges from P 1/1 to P1/256
M
in mode and P1/1 - P1/32 in
