ACES Transform
Lets you perform the kind of color transforms that the ACES Input Device Transform and ACES
Output Device Transform parameters of the Color Management panel do, without the need to
have ACEScc or ACEScct enabled.
ACES Version: When you’ve chosen one of the ACES color science options, this pop-
up becomes available to let you choose which version of ACES you want to use. As of
DaVinci Resolve 15, you can choose from ACES 1.0.3 or ACES 1.1 (the latest version).
Input Transform: This pop-up menu lets you choose which IDT (Input Device Transform)
to use to process the image. It presents the same options that are available in the Color
Management panel of the Project Settings.
Output Transform: This pop-up menu lets you choose an ODT (Output Device
Transform) with which to transform the image data for monitoring on your calibrated
display and when exporting a timeline in the Deliver page. It presents the same options
that are available in the Color Management panel of the Project Settings.
For more information about the options available in these parameters, see Chapter 7, “Data
Levels, Color Management, and ACES.
NOTE: This plug-in does ACES transforms correctly using the transforms specified by
the Academy, whereas the Color Transform plug-in does transforms to the ACES color
space colormetrically, which is not actually correct for ACES workflows.
Chromatic Adaptation
A Color category plug-in that lets you precisely transform an image that has been lit or
processed assuming one specific color temperature to another user-selectable color
temperature. This transformation alters the appearance of all colors in the image as perceived
by the human vision system in the same way that a new illuminant would, whether that illuminant
is a light in the environment being recorded or the color temperature of a display on which the
image is shown. This plug-in is useful for performing specific color temperature transformations
as part of color management workflows or for setting up precise color temperature adjustments
as part of a creative grade.
You control this transformation by using pop-up menus to define the Illuminant Type of the
source (typically the color temperature the camera was set to), and that of the target that you
want to transform the image to. For both sets of controls, you can choose a Standard Illuminant
from a list, a Color Temperature via a slider, or CIE 1931 xy coordinate values. This plug-in also
takes into account the current color space and gamma of the clip, which default to the current
Timeline Color Space.
This image transform is extremely precise because the image is first transformed from the
Timeline Color Space to XYZ, and then it’s transformed to match the LMS (long, medium, short)
color space that models the cone response of the human eye to colors lit by different
illuminants.
