Photo-Accurate Dimming™
The dimming curve on the Lightblade Edge 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.
The following table shows the relationship between LOCAL values as they relate to camera stops:
DMX Value
(0-100)
20%
40%
60%
80%
100%
Here are examples of how to accurately match camera stops to dimming levels in Local Mode:
Local Dimming: The Rule of 20 (0-100 scale)
Increase output 1 Stop: Add 20 units (fc/lux is doubled)
Decrease output 1 Stop: Subtract 20 units (fc/lux is reduced 50%)
Adjust ½ Stop = 10 Units (0-100)
Adjust ¼ Stop = 5 Units (0-100)
When operating in DMX mode, each increase of 50 units (8-bit) doubles the light output, or the
equivalent of opening the lens 1 f-stop.
