Узел Tone Map
Tone mapping is a technique used in image processing and computer graphics to map one set of colors to another in order to approximate the appearance of high dynamic range images in a medium that has a more limited dynamic range.
Essentially, tone mapping addresses the problem of strong contrast reduction from the scene values (radiance) to the displayable range, while preserving the image details and color appearance. This is important to appreciate the original scene content.

Свойства
- Type
- Rh Simple
- Key
The value the average luminance is mapped to.
- Offset (смещение)
Normally always 1, but can be used as an extra control to alter the brightness curve.
- Gamma
If not used, set to 1.
- R/D Photoreceptor
- Intensity
If less than zero, darkens image; otherwise, makes it brighter.
- Контраст
Set to 0 to use estimate from input image.
- Adaptation
If 0, global; if 1, based on pixel intensity.
- Color Correction
If 0, same for all channels; if 1, each independent.
