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 all the white chips on the test chart are yellow this suggests that a sig-

nificant portion of the monitor path video is at the maximum legal 100 IRE value.
Because the scene is over exposed, when the recorded .R3D file is color corrected in post-production,

the scene’s highlight information will almost certainly be clipped, however the shadow information will

probably display cleanly once pulled back down to an acceptable brightness.

APPROPRIATE EXPOSURE

ISO 800 - Monitor Output

In this image the camera is appropriately exposed for this scene. The monitor is neither very dark nor very

bright and the histogram is spread evenly given that there are bright highlights on the coin we wish not to

blow out. Note that there is no red bar on either the left or right edges of the histogram and the vertical

color stack to the right of the histogram is at yellow. These indicators suggest that there is no significant

amount of the sensor’s RAW data “in the noise” or “at clip”, and that the peak level of the sensor’s RAW

data is about 2/3 stop below clipping.
