Lower left knob (Large) Photo-Accurate Dimming
The dimming curve on the LB800 follows a strategy that provides relative output levels that correspond
to image capture. Both DMX values and local control levels directly correlate to camera stops in a
meaningful way. The result is extremely predictable light levels within the full output range of the fixture.
0-100% dimming is controlled by turning the large knob. Pushing the knob cycles the output at these
levels: 20%, 40%, 60%, 80% and 100%.
The following table shows the relationship between LOCAL values as they relate to camera stops:
