Colour Management
Colour management enables the desired colour values to be represented as accurately as possible throughout the finishing
process. It is different from colour correction in that its intention is not to change colours but instead to preserve the
perceived colour in different situations.
NOTE Colour management is performed with the LUT Editor and other controls that are labelled "LUT", but other operations
including colour transforms and gamma functions are supported in addition to look-up tables.
Colour Management Workflow
Colour management works by applying colour transforms and other operations at various stages of the
pipeline. Typically, you use colour management when:
Importing media. Images from different sources (such as digital cameras, scanned film, 3D renders, and
matte paintings) often use different colour spaces and encodings, and they should be converted to a
single working colour space.
Outputting media. Different output formats require different encodings depending on the medium and
expected viewing conditions.
You might also want to apply colour transforms to convert into and out of a specific colour space in order
to perform a particular operation. For example, operations like compositing or lens blur work best in a linear
colour space, while operations like tracking and edge detection work best in video or log colour space.
In addition, colour management is used to display images in Smoke to ensure that the colours on the monitor
and projector match what will be displayed on the final output as closely as possible. For example, if you
are working in the ACES colour space, you can apply the ACES_to_current-monitor transform.
Applying Colour Management to Clips
There are two ways to apply colour management to clips:
Auto Mode: Auto mode, availabale in the MediaHub, uses rules and format-specific colour space preferences
to automatically convert various types of media to a common scene-linear Working space, on import.
Manually: Use the LUT Editor to manually select the colour transform(s) to use in the order of your
choice.
