5.6.5 Ramp shutter angle /
compensation iris
The shutter angle is continuously adjusted within the pre-
defined limit values over a pre-defined period of time
after pressing the RAMP button in the camera run
(master value: Shutter angle).
The iris of the lens is automatically adjusted by the WRC-1
within the pre-defined limit values to compensate the
exposure. The visible depth of field can be altered with
this function.
If the iris control is not available, the flashing warning
‘NO IRIS’ is displayed in the main menu. Connect the iris
control as described in chapter 4.1.2, calibrate the lens
and assign the T-stops as described in chapter 5.5.1!
In the main menu the current shutter angle is shown in the
first display line. The automatically calculated T-stop is
shown in the second line.
The display shows full T-stops followed by the tenth of a
T-stop. Example: T-stop 2.8 plus half a T-stop is shown as
2.8_5. The tenths of a T-stop are linearly divided between
the two full T-stop positions.
The ‘PROG’ symbol indicates that a time-controlled ramp
function has been selected.
