Filming with HMI Light
When lighting scenes with HMI/CID-discharge lamps, the
pulsing light intensity is dependent on the supply frequency.
To achieve constant exposure, the camera’s frame rate, the
supply frequency of the lighting and the angle of the mirror
shutter must all relate to each other. As the camera frame
rate and the supply frequency of the lighting are normally
given, compensation must be carried out through the angle
of the mirror shutter.
The following table indicates the mirror shutter angle that
needs to be set:
