Search TipsC_ColourMatcher
C_ColourMatcher aims to produce a global gain-based color correction across all the views in a rig to balance out differences in exposure and white balance. It solves across all cameras to find the minimum required gain changes to ensure color similarity.
Note: C_ColourMatcher does not compensate for color shifts not resulting from exposure- or gain-type differences. It also does not deal with gamma- or offset-type differences.
Color matching relies on solve data and should be performed before stitching the solved camera output together, so ideally, place C_ColourMatcher between C_CameraSolver and C_Stitcher.
Tip: The CaraVR plug-ins include example scripts in Nuke's toolbar under CaraVR > Toolsets.
