Setting procedure for TTL mode (Fig. 6)
With some cameras the TTL mode is automa-
tically activated on the mecablitz in mode
"P" (or "HYP" or "green square") or a pic-
ture mode when the manual mode M or MLo
is selected on the mecablitz.
• Turn on the mecablitz by its main switch.

Continue depressing the „Mode" key until „TTL"
flashes on the LC display.
• The setting becomes immediately effective. The
LC display returns to its normal state after
approx. 5 sec.
Pronounced differences in contrast, e.g. a dark
subject in snow, may make it necessary to correct
the exposure settings (see 4.1.2).
4.1.1 Automatic TTL fill-in flash in daylight
Most cameras automatically activate the fill-in
flash mode in daylight (see camera's operating
instructions) when in Full Auto Mode, Program
"P" (or "HYP" or "green square") or a Subject
Program Mode.
Fill-in flash overcomes troublesome dense sha-
dows and produces a more balanced exposure
between subject and background with contre-jour
shots. The camera's computer-controlled metering
system sets the most suitable combination of shut-
ter speed, working aperture and flash output.
Ensure that the contre-jour light source does
not shine directly into the lens as this will
mislead the camera's TTL metering system!
In this instance there is no setting or display on
the mecablitz for TTL fill-in flash.
4.1.2 Manual TTL flash exposure correction
The TTL auto flash mode of most cameras is
matched to a 25% degree of light reflection by the
subject (average amount of light reflected by
flash-shot subjects). Consequently, a dark back-
ground that absorbs a great deal of light, or a
bright background that reflects a great deal of
light, can result in under or over exposure, re-
spectively.
To offset this effect a correction value can be set
on some cameras to manually match the TTL flash
exposure with the photographic situation (see
Table 1 or refer to the operating instructions for
your camera). The actual extent of correction
depends on the contrast prevailing between
