5.5.4 Iris / compensation user
Using the handwheel, the iris can be manually adjusted
within the user-defined end-stops, simultaneously together
with the values for the shutter angle and the camera speed.
If appropriate values are selected, either the exposure can
be kept at a constant level, or an adjustment process can
be defined to change the exposure as required (e.g.
fading in or out).
Note: The function of the user mode always remains
the same, irrespective of the position of the WRC
rotary switch (Iris,
) or fps): The timing of the
simultaneous adjustment processes is controlled
using the handwheel. If a ramp function is
selected (ramp Iris, ramp
) or ramp fps), a
ramp duration can be defined. In this case the
handwheel is without function in the main menu.
Differences in exposure are not automatically
compensated for.
