5.7.13 Ramp speed / compensation
max. shutter angle
The camera speed is continuously adjusted within the pre-
defined limit values over a pre-defined period of time after
the RAMP button is pressed in the camera run (master value:
Camera speed). The mirror shutter angle is automatically
adjusted by the WRC-1 to compensate the exposure. If the
adjustment range of the shutter angle is insufficient for the
given end value, the rest will be compensated for by the
aperture of the lens. In this case, the aperture proportion
is evenly distributed over the entire compensation range.
The first line of the main menu shows the automatically
calculated value of the shutter angle and the symbol ‘F’ to
indicate the iris control. The second line shows the current
camera speed.
The ‘PROG’ symbol indicates that a time-controlled ramp
function has been selected.
By pressing the SET button, the currently adjusted T-stop
can be shown in the first display 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.
