Use the tonemap imager to artistically modify the image's tone mapping using a filmic or a modified Reinhard curve. Both the strength and the length need to be different from 0, for the toe and shoulder to make a difference.
Mode
Tonemap mode.
Filmic
Filmic Toe Strength
Amount of curvature for the tonemap curve in the darker values.
Filmic Toe Length
Amount of darker values affected by the toe.
toe_strength:0.5
Filmic Shoulder Strength
Amount of curvature for the tonemap curve in the brighter values.
Filmic Shoulder Length
Amount in f-stops of brighter values affected by the shoulder.
Filmic Shoulder Angle
Curve slope when white is reached.
Reinhard
Reinhard Highlights
Reinhard photographic tonemap operator strength.
Reinhard Shadows
Additional tone mapping control for darker values.
LUT
Mode
LUT file selection mode:
- file: Select a single LUT file.
- folder: All LUT files from the selected folder and its subfolders are listed in a combo box to choose from.
LUT
Specifies the LUT file to load.
Directory
Specifies the directory to load LUT files from.
Working Color Space
It is possible to specify a working color space here to convert to the specified space, apply the LUT, and convert to linear or rendering color space again.
Mix
0 preserves the input untouched and 1 applies the full node effect.
Preserve Saturation
Preserves color saturation for extreme bright values. This is for values that are beyond 1, if you don’t preserve saturation they go to white, otherwise, they keep their color.
Disabled (default). Rollover image to view enabled.
Gamma
Gamma curve exponent for midtones value control.
