The American Society of
Cinematographers Colour Decision
List (ASC CDL) is a format for the
exchange of basic primary colour
grading information between
equipment and software from
different manufacturers. The Pluto
software can be used to create,
modify or simply load and apply
CDLs.
To load an existing CDL, Ensuring
Enable
is selected, click
Load
to browse to
the .cdl or .cdn file and click
Open
. The CDL is then loaded in to the GUI as a
numerical and graphical representation of the file and applied to the video
signals.
If in Stereo mode, use the
Left
,
Right
or
Both
to apply the look to individual
camera feeds as required.
The CDL is treated as a 1D LUT by the Pluto. If the CDL is to be used in
conjunction with a 3d Cube, use the
Input
or
Output
to decide if the CDL should
be applied before or after the cube. For example, if the cube has been created
as a monitor transform LUT and the CDL is an on-set look; for this the CDL
should be
Input
.
The format defines the maths for three functions: Slope, Offset and Power. Each
function uses a number for the red, green, and blue colour channels for a total of
nine numbers comprising a single colour decision. A tenth number, Saturation,
specified in the Version 1.2 release, applies to the R, G, and B colour channels in
combination.
The functions can be modified in one of four ways; either with a Kensington
trackball, by entering numerical values directly in to the numerical fields, using
the up/down arrows to finely adjust the existing numbers, or using a mouse with
the graphical tracker ball view (see next page).
