Gamma
Declares the gamma/log domain of the incoming image.
Choose the actual working transfer function so luminance mapping behaves predictably.

GamutMapping
Tone and gamut mapping
Maps luminance and gamut between source and output conditions using selectable tone-mapping and gamut-mapping methods.
GamutMapping
DaVinci Resolve · Fusion
GamutMapping is designed for controlled compression of luminance and chroma when source values exceed the practical range of the target display or color volume.
Overview
What GamutMapping does
GamutMapping is designed for controlled compression of luminance and chroma when source values exceed the practical range of the target display or color volume.
Mental model
Instead of chopping off values that do not fit, reshape the source brightness and color volume so important relationships survive inside a smaller target range.
Common uses
Compress HDR-like highlights
Map wide-gamut saturation into a smaller target
Prepare scene-referred imagery for a display-referred branch
Compare different tone-mapping strategies

Important parameters
Start with these controls before reaching for more complicated workarounds.
Gamma: Linear
Uses Linear for gamma.
Gamma: Log / DaVinci Intermediate / Camera Logs
Uses Log / DaVinci Intermediate / Camera Logs for gamma.
Gamma: Gamma 2.2 / 2.4 / 2.5 / 2.6
Uses Gamma 2.2 / 2.4 / 2.5 / 2.6 for gamma.
Tone Mapping Method
Selects the luminance compression algorithm.
Methods range from no mapping or clipping to smoother luminance- and saturation-aware compression.
Tone Mapping Method: None
Uses None for tone mapping method.
Tone Mapping Method: Clip
Uses Clip for tone mapping method.
Tone Mapping Method: Simple
Uses Simple for tone mapping method.
Tone Mapping Method: Luminance Mapping
Uses Luminance Mapping for tone mapping method.
Tone Mapping Method: DaVinci
Uses DaVinci for tone mapping method.
Tone Mapping Method: Saturation Preserving
Uses Saturation Preserving for tone mapping method.
Max. Input Luminance
Defines the expected upper source luminance.
Set this to meaningful source conditions rather than an arbitrary number.
Max. Output Luminance
Defines the target peak luminance.
This controls how aggressively highlights need to be compressed.
Avg. Input Luminance
Provides a scene-average reference for methods that use it.
A realistic average helps maintain midtone intent.
Gamut Mapping Method
Chooses how out-of-gamut color is compressed.
Select a method that balances hue stability, saturation and target-gamut fit.
Gamut Mapping Method: None
Sets Gamut Mapping Method to None.
Gamut Mapping Method: Saturation Compression
Sets Gamut Mapping Method to Saturation Compression.
Gamut Mapping Method: Clip
Sets Gamut Mapping Method to Clip.
Apply Forward OOTF
Applies the selected color space’s forward opto-optical transfer function before gamut mapping.
Apply Inverse OOTF
Applies the inverse opto-optical transfer function as part of the gamut-mapping transform.
Pre-Divide / Post-Multiply
Controls premultiplied-alpha handling around the operation.
Pre-divide removes alpha multiplication before processing; post-multiply restores it afterward. This is useful when color work creates dark or bright fringes around translucent edges.
Practical setup
A reliable workflow
- 1
Identify the source gamma and approximate luminance range.
- 2
Set the target peak output luminance.
- 3
Choose a tone-mapping method and compare highlight roll-off.
- 4
Enable an appropriate gamut-mapping method for saturated colors.
- 5
Evaluate skin, highlights and saturated graphics rather than relying on one test frame.

Common mistakes
Using incorrect luminance assumptions
Choosing Clip when highlight detail must be preserved
Applying tone mapping multiple times in different parts of the pipeline
Production notes
Practical tips
Keep source and target assumptions documented in node comments.
Judge mapping on moving footage and scopes, not just a single still frame.
