Using OpenColorIO

In addition to 32-bit editing support, Affinity Photo also implements OpenColorIO; a colour management system that provides a full colour managed workflow. It is predominantly used for motion picture production but can be used for any situation where accurate end-to-end colour management is required.

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 Colour (ACES) configurations.

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

Using OpenColorIO

OpenColorIO is exposed in Affinity Photo through two methods:

OCIO Adjustment

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