Tone Mapping
Tone mapping is disabled by default in order to insure a continuity in the colorimetric and the rendering between the real-time OpenGL engine in Patchwork 3D and the Iray raytracer.
Exposure: compensation for the exposure of light in the scene
Burn highlights
Crush shadows
Saturation
White balance: can be set via a choice of standard values, a personalized Kelvin value, or with the color chooser
Photographic tone mapping: replaces the exposure value with photographic exposure settings. These settings include the Cm2 factor, the sensor sensitivity ISO, the F-number of the aperture, and the shutter speed.
The reset button restores the default tone mapping settings.
