LUTs and ACES
The academy that promotes the correct use of ACES strongly recommends that LUTs be
processed in the ACES color space. For this reason, two project settings let you choose how
this will be done:
 ACEScc AP1 Timeline Space: This setting works for either the ACEScc or ACEScct
Color Science settings depending on what you’ve selected in the Color Science pop-
up at the top of the Color Management panel in the Project Settings. This setting lets
you use LUTs that were created for ACES workflows that are similar to (but not the
same as) LUTs you would create and use in a traditional log-encoded workflow. LUTs
designed for working with this setting should have a range of –0.358 to 1.468 so that
grading operations that clip an image from 0 to 1 won’t destroy the look being applied.
The “ACEScc AP1 Timeline Space” setting is also good for workflows where you want to
use conventional LUTs that were designed for Rec. 709 workflows using the
ResolveFX “ACES Transform” plug-in, which over a series of three nodes lets you
transform the image from ACES to 709, apply a Rec. 709-designed LUT, and then
convert the image from 709 back to ACES.
 ACES AP0 Linear: This setting requires you to apply an LMT LUT that has been
specifically created for ACES image data. Only use this setting if you’re using CLFs
that are designed for ACES using a range of –65504 to 65504, as specified by
SMPTE 2065.
Adding Lookup Tables of Your Own
The menus in the Color Management panel of the Project settings include a series of factory
preset LUTs that were installed with DaVinci Resolve, along with any LUTs that have been
generated by DaVinci Resolve, or that you’ve imported into the proper directory for your
operating system for your own use.
 On OS X: Library/Application Support/Blackmagic Design/DaVinci Resolve/LUT/
 On Windows: C:\ProgramData\Blackmagic Design\DaVinci Resolve\Support\LUT
 On Linux: /home/resolve/LUT
If you downloaded the non-studio version of DaVinci Resolve from the Apple App Store, LUTs
are saved in a different location in order for DaVinci Resolve to remain totally self-contained. In
this case, you can click the Open LUT Folder button in the Lookup Tables panel of the Project
Settings, to open up a Finder window at the location these LUTs are stored. You can use this
window to copy LUTs that you want DaVinci Resolve to have access to, or delete LUTs that you
no longer need.
If you add a LUT to one of these directories after DaVinci Resolve has been opened, you can
click the Update Lists button to refresh the contents of the pop-up menus.
