On the Gamma and LUT panel of the Preference
Settings dialog, you set options to adjust the
Gamma (page 3–948) and lookup-table (LUT)
values for input and output images and for the
monitor display.
The LUT functionality provides support for the
same-named feature in other Autodesk Media and
Ente rtainment software such as Combustion and
the systems suite: Inferno, Flint, Smoke, etc. This
feature allows studios to implement a consistent
way of displaying colors, assuming that their
monitors are calibrated to the same reference.
Thus 3D artists can produce results that are closer
to what the compositor expects by eliminating
a variable in the equation: the way colors are
displayed on screen.
Note: The lookup table controls available here
do not affect exposure control or lighting of the
scene. While they do affect t he colors of the final
image, this is with regard to the display only. By
having a reference across a studio (with calibrated
monitors), using standardized lookup tables
minimizes variability in rendered output.
Also, please note t hat t he LU T system of the
systems suite is complex and offers a variety of
