5.3 P-TTL flash mode

The P-TTL flash mode with measuring preflash is a further development of the
standard TTL flash mode of analogue cameras. During the shot and before the
actual exposure, one or more almost indiscernible preflashes are executed by the
flash unit. The light reflected by the preflash is evaluated by the camera.
According to the evaluation, the subsequent flash exposure will be adjusted by
the camera to suit the situation (see the camera's operating instructions).
Depending on the camera model, the preflashes precede the main flash
by such a short interval that they practically cannot be distinguished from
the main flash! The preflashes do not contribute to the lighting of the shot.

5.4 P fill-in flash mode
/
With most camera models, the auto programme mode P and subject program-
mes activate the automatic fill-in flash mode in daylight (see the camera's opera-
ting instructions) when in TTL- or P-TTL mode.
With the fill-in flash you can remove annoying shadows and achieve a balanced
exposure between motive and background in shots with backlight. A computer-
controlled metering system takes care of the appropriate combination of shutter
speed, working aperture and flash output.
Ensure that the frontlighting source does not shine directly into the lens, as this
will interfere with the camera's TTL metering system.
Ensure that the contre-jour light source does not shine directly into the
lens, as this will interfere with the camera's TTL metering system.
An adjustment or display for the automatic TTL fill-in flash mode on the flash unit
doesn't occur in this case.

5.5 Automatic flash mode

In the automatic flash mode A, the flash unit sensor
reflects back from the subject. The sensor
only measures the light for the time a flash is fired by the mecablitz. The flash is
cut off as soon as sufficient light has been emitted for correct exposure. The sen-
sor of the mecablitz has to be directed at the subject.
The maximum range is shown on the LC display. The shortest shot distance is
approximately 10% of the maximum distance range. The subject should be loca-
ted within the middle third of the distance range shown on the LC display to
allow the electronic system sufficient leeway for compensation.
Setting procedure:
• Press the „Mode" button until „Mode" flashes on the LC display.
