14.4 Exposure Calculation

The exposure calculation is a very powerful feature of the WRC-2. It reduces the workload of a ramp exposure calculation to a simple transfer of the exposure value from a light meter to the WRC-2.

Once the working f-stop for a shot is determined by the DP and entered in the WRC-2, all exposure compensations will be calculated automatically.

To Enable the Exposure Calculation:

●In the Ramp Menu click on „Options“

●Check „Enable“ in the Exposure Meter Window

●Enter speed and shutter values of the exposure meter that is used on the set. (values will be stored)

●Click „Exit“ to go back to the Ramp Menu

Use the Exposure Calculation:

●Measure the light to determine the working f-stop.

●Click on the „Exposure Meter“ Window and enter the working f-stop by using the sliders.

●Read the calculated f-stop in the Iris Display and set the iris value on the lens.

Note: Since there is no compensation selected, the current settings will lead to a two stop underexposure. See the Exp. Diff. (Exposure Difference) indicator window.
