Select False Color – Video: note the √ V icon in the GUI when active. This mode allows us to check the

RGB video levels of the scene. As the peak white chips on the test chart are showing up in green and the

underexpose areas are showing up in dark blue, this says the monitor path video levels are only ranging

between 44 IRE and 1 IRE.

Because the scene is under exposed, when the recorded .R3D file is color corrected in post-production,

the scene’s highlight information will certainly not be clipped, however the shadow information will proba-

bly display with significant noise once pushed to an acceptable brightness.

OVEREXPOSURE (~ 2 STOPS)

ISO 800 - Monitor Output

In the image above it is fairly obvious the camera is over exposed. The monitor is very bright and the his-

togram is justified to the right. Note the red bar at the right edge of the histogram and the vertical color

stack to the right of the histogram is showing red plus the three traffic lights to the right of that are all illu-

minated. These indicators are suggesting that a signification portion of the sensor’s RAW data is “at clip”,

and this clipping is occurring on Red, Green and Blue channels.
