ZEBRA MODES

Use Zebra mode to enable and adjust the upper and lower values for two (2) independent zebra indicators. Use Zebra
1 for highlight exposure, and use Zebra 2 for mid-tones or shadows. Zebras are disabled by default.

2. Set a Low IRE of 98.

3. Set a High IRE of 100.

Areas of the image exposed within the IRE range are indicated by red diagonal lines at –45°.

The default settings are Low IRE = 98 and High IRE = 100.

The default settings are Low IRE = 41 and High IRE = 48.

ZEBRA OVERVIEW

Zebra is a specialty mode that is capable of showing up to two customized overlays with arbitrary IRE ranges. Unlike
the other two modes, Zebra indicators appear as diagonal stripes, they are fully configurable, and they have the
advantage of preserving a full-color base image.

With traditional video cameras, many used a single zebra to indicate highlight detail. It would often be set at 70% (70
IRE), in part because this is where a white piece of paper would begin to have minimal texture when rendered using a
typical contrast curve. Skin tones or skies would be exposed to appear just darker or brighter than these lines. If
enabled, a second zebra would typically indicate either mid-tones or shadows. For deep shadows, you can set the
second indicator to below 10% intensity or 10 IRE, and set the first indicator to highlights above 85 IRE.

However, as with other IRE-based modes, Zebra mode is only applicable for the current ISO settings (such as with
SDI output), not for the raw image data. If anything is changed in post-production, the indicators won't be
representative of the final output tones. In those situations, Zebra mode is more of a preview and output brightness
tool than an exposure tool.
