What is false color?
In film production, exposure needs to be spot-on, determining the quality of the footage and flexibility given in post-production. One method to evaluate a video signal’s correct exposure is false color: Different exposure levels within a given frame are translated into a representative color displayed as an overlay. While interpreting video scopes such as a waveform might be challenging and needs lots of practice, false color is more accessible as it corresponds directly with the details in the frame. Both Livegrade Pro and Studio come with a built-in false color mode.
How to apply false color?
False color indicates specific luma ranges within an image, usually given in IRE values from 0 to 100. Most commonly, red color points to areas that tend to clip in the highlights, whereas purple ranges mark clipping in the shadows. Further colors in the scheme often indicate ideal IRE values for medium grey or skin tones. Remembering the underlying log-encoded format is the most important aspect when applying false color. Every format is different and needs another way of being interpreted. Livegrade includes presets for the most common log-encoded formats, such as ARRI LogC4 or SONY Slog3.
3 use cases worth to create your custom false color
Adapt Ranges to Your Needs
If your show look needs to be very precise on exposing specific luma values, take an existing preset and add custom ranges as they best cover your needs. In this example, the ARRI LogC4 preset was used, complemented by ranges to indicate different luma values of the sky.
Consistent False Color Schemes
Switching between different cameras and their respective log-encoded formats might be confusing, as each format has a different false color scheme to remember. The False Color LUT Creator lets you choose a particular preset to stick to the correct IRE ranges but adapt the false color scheme to what you are most familiar with. (See example: ARRI LogC4 / maintained values of LogC4 but adapted to Sony false color scheme).
Shooting HDR needs delicate handling, according to the requirements of viewing devices. Define custom false color ranges for HDR signals to focus on specific levels, such as 100-nits that is often used for diffuse white.
