Black knee determines the amount of additional gain applied to the black
end of the RGB transfer functions in the look-up tables.
The value displayed is a percent of the available correction.
A positive black knee parameter will increase the slope of the first 15% of
the transfer function by the amount entered and decrease the slope of the
next 15%, to return to the unmodified transfer function.
The figure below displays increased and decreased black knees.
The default is 0, and the range is ±100.
