7.12 Contrast

To facilitate subject and pictorial composition, the camera flash can be combined
with an external flash unit (mecablitz) to perform so-called contrast control when
in TTL- or P-TTL flash mode. Here the camera flash provides 1/3 of the required
flash power and the external flash unit provides the remaining 2/3.
Please observe the maximum possible flash range (guide number) of both
flash units to ensure the correct operation of the contrast control!
The benefits of contrast control can, however, only be optimally exploited if the
external flash unit is set up at a reasonable distance from the built-in camera
flash. To do so, the following original Pentax accessories are available:
