14. Ramp Control Menu

In the Ramp Control Menu speed and shutter ramps can be programmed. After enabling the Iris Control, also iris ramps can be performed. If a speed ramp is to be compensated by iris and shutter simultaneously, the ratio of both values can be mixed via the Compensation Mix Slider.

The actual status and position of the ramp is shown in the Ramp Display by the yellow arrows. When the ramp is performed, the arrows move along the ramp display from the start values to the end values providing a clear situational awareness of the running ramp.

The Exposure Calculator helps calculating the working T-stop. Simply measure the light on the set with your light meter and standard settings (e.g. 24fps, 250ASA) and enter the measured T-stop in the calculator (T- stop input window). The working T-stop that has to be set on the lens will then be computed and displayed in the Ramp Display. When the Iris Control is enabled, the iris will be set automatically to the correct value via the lens motor.
