Zebra patterning

Zebra patterning (or zebra stripes) is a feature found on some prosumer and most professional video cameras to aid in correct exposure. When enabled, areas of the image over a certain threshold are filled with a striped or cross-hatch pattern to dramatically highlight areas where too much light is falling on the image sensor. Often, a threshold level can be set, e.g. 70%, 80%, 90%, or 100% (with 100% meaning pure white, or over-exposed, AKA 100 IRE). A lower threshold like 70-80% can help correctly expose many skin tones, while higher numbers help ensure correct overall scene exposure.[1][2][3][4][5][6]
