Gamma Matrix



The Gamma Matrix tool applies a matrix colour transformation to your image sequence. A gamma correction factor can also be set before and after this transformation is applied. You can define and apply presets for both the gamma correction and the colour matrix.



The gamma function applied here is based on a standard power law mathematical expression.



Compared to a 3D Lookup Table, the Gamma Matrix tool allows for a more precise and efficient way to convert between various colour domains e.g. RGB to/from XYZ or RGB Rec709 to/from RGB DCI-P3 etc.



This tool is not designed to convert between video and film colour domains (e.g. film look or negative density).




The Enable toggle button enables/disables application of the effect. Toggling this off will cause the effect to take no part in the processing chain.
