Using OpenColorIO

Setting up OpenColorIO

By default, Photo's OpenColorIO features are not immediately usable. An .ocio configuration file is required alongside a number of supporting files such as lookup tables.

The OpenColorIO website (http://www.opencolorio.org) contains some sample configurations that provide a number of suitable input and output profiles, including several Academy Color (ACES) configurations.

To configure OpenColorIO in Photo:

Download and extract your chosen OpenColorIO configuration to a folder.
From the Affinity Photo menu, select Preferences.
From the Edit menu, select Preferences.
On the Color tab, under OpenColorIO Configuration File, choose Select and navigate to the extracted folder. Choose the .ocio configuration file within this folder.
Under OpenColorIO Search Folder, click Select and choose the extracted folder (it should already be the current highlighted folder from when the .ocio configuration file was selected).
You will be prompted to restart the app, which is necessary for the OpenColorIO settings to take effect.

Using OpenColorIO

OpenColorIO is exposed through two methods:

The 32-bit Preview panel contains a Display Transform option that only becomes available with a valid OpenColorIO configuration. This can be used to achieve a non-destructive, color managed workflow. See 32-bit Preview for more information.
An OCIO adjustment layer (see OCIO Adjustment) can be added to losslessly convert between color spaces. You can have multiple OCIO adjustment layers within a document, which allows you to accommodate composite layers from different color spaces. An example layer stack might be (in hierarchical order):
- OCIO Adjustment—from Utility - Linear - sRGB back to Role - scene_linear
- sRGB Pixel Layer—composite element
- OCIO Adjustment—from Role - scene_linear to Utility - Linear - sRGB
- Pixel Layer—original layer

An OCIO Adjustment layer going from Role - scene_linear to Utility - Linear - sRGB.
