This correction allows you to control different types of mapping curves, make gamma correction and select a color space. Note that color values are mapped per channel.
Tone mapping space – Specifies the color space where the operator is applied. Converts the image to the selected space and back, if needed. You can choose between Linear sRGB and ACEScg. For more information about ACEScg, visit theACEScg Workflow Setuppage.
Type – Specifies the type of curves used for the tone mapping. You can choose between Linear, Hejl-Dawson, AMPAS (ACEScg), Hable, and PowerCurve.
Log space – Converts the image to log space before applying the tone mapping.
Gamma – Specifies the gamma correction. It is applied before the operator.
Use blue fix – Applies an additional transformation to ACEScg primitives that results in pure blues burning out through cyan instead of magenta. Available when Tone mapping is ACEScg.
AMPAS (ACEScg)
AMPAS mode applies an approximate ACES standard curve.
Hejl-Dawson Type
Shadows – Shadow compression. Higher values darken the shadows, while also brightening the mid tones.
