OpenColorIO-Config-ACES 1.0.0

The Working Group is pleased to announce the stable release of the new OpenColorIO Configuration(s) for ACES.

It is the culmination of almost two years and half of work and countless bi-weekly meetings. Those configs were designed to be lightweight and use the new features of OpenColorIO 2. We hope that they will be useful for the community and that they pave the way toward an increased adoption of OCIO 2.

We sincerely thank all the authors and contributors from the original OpenColorIO-Configs as it was always ingrained in all our discussions and decisions. We also thank all the contributors that gave feedback and participated into the Working Group meetings.

Config Naming Convention

Those new configs adopt an advanced naming convention so that they can be uniquely identified:

studio-config-v1.0.0_aces-v1.3_ocio-v2.1.ocio
|-----|-------------|---------|---------|---|
|Type | Colorspaces | ACES    | Profile |   |

Where:

Type : The type of the config, e.g. Reference, CG or Studio.
Colorspaces : The colorspace definitions versions, semantically versioned.
ACES : Supported aces-dev version.
Profile : Supported OCIO profile, greater versions will enable more features, e.g. ACES 1.3 Reference Gamut Compression for 2.1 profile.

Summary of the Studio Config

This config is geared toward studios requiring a config that includes a wide variety of camera colorspaces, displays and looks.
