ACES in PhotoshopThere are multiple ways to add an
ACEStransform to footage
in Photoshop, the most common methods are covered below.
ACES via fnord OpenColorIO Plugin for Photoshop
ACES via a LUT in Photoshop
For this OCIO demonstration and any Redshift project that uses the default OCIO ACES settings you should use the ACEScg_Photoshop_to_sRGB_ACES_1.0_SDR-Video.csp LUT file.
Now the ACEScg footage looks good and is working as expected with the properly setup Color Lookup Adjustment Layer.
The correct way to adjust ACEScg footage with this Photoshop workflow is above your ACEScg footage but below the Color Lookup adjustment layer. This is demonstrated below with an Exposure effect being applied to an adjustment layer titled "Color Correction" in between the two layers. The reason for this is that you want to apply any color corrections to the ACEScg footage when it is still linear so it must be done before the ODT conversion that converts your image to non-linear via the Color Lookup. This also means that you can composite multiple ACEScg openEXRs render layers all under the same one Color Lookup adjustment layer.
ACES in After Effects
OCIO Support for After Effects is still less than ideal, for now the best way to use ACES in After Effects is to first download and make use of the fnord plugin OpenColorIO for After Effects.
First import your ACEScg footage into After Effects and place it in a new composition.
Now set up your Project Settings. This can be found either by clicking the small button at the bottom of the Project panel circled in the image below or going to File > Project Settings.
Under the Color tab set the following settings:
Depth: 32 bits per channel (float)
Working Space: sRGB IEC61966-2.1
Linearize Working Space: Enabled
Next create a new adjustment layer above your ACEScg footage in the composition. We will name this adjustment layer and refer to it as "ACEScg to sRGB."
Then add an OpenColorIO effect to the "ACEScg to sRGB" adjustment layer. This effect is found under Effects > Utility > OpenColorIO.
Now set your OCIO config location for the OpenColorIO effect.
Use the following settings:
Set the mode to "Display"
Input Space: ACEScg
Output Space: sRGB
View: ACES 1.0 SDR-video
Now the ACEScg footage is being previewed with the correct ACES ODT but it still does not actually look correct in After Effects, this is due to an extra gamma correction that After Effects color management is applying.
To counteract this gamma correction issue add a Color Profile Converter effect beneath the existing OpenColorIO effect, this can be found under Effects > Utility > Color Profile Converter.
Use the following settings for the Color Profile Converter:
Input Profile: sRGB IEC61966-2.1
Output Profile: sRGB IEC61966-2.1
Linearize Output Profile: Enabled
Now the ACEScg footage looks correct and will render out properly.
