5.5.7 Ramp iris / compensation user
The iris of the lens is continuously adjusted, together with
the shutter angle (if controlled by the WRC-1) and the
camera speed, within the freely definable limits over a
pre-defined period of time after pressing the RAMP button
in the camera run.
If appropriate values are selected, either the exposure can
be kept at a constant level, or a ramp 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.
The ramp is started while the camera is running
by pressing the RAMP button. In this case the
handwheel is without function in the main menu.
Differences in exposure are not automatically
compensated for.
