Apple’s log format being known is all it takes for compatibility with ACES, the Academy of Motion Picture Arts and Sciences color management system. But it’s important to note that Apple Log does not match any pre-existing ACES format.

The log curve is Apple’s own, which they’ve documented, and it’s already available in DaVinci Resolve. In the CST node, choose Apple Log for the Input Gamma, but choose Rec. 2020 for the Input Color Space, because Apple Log uses the Rec. 2020 primaries.

With these as your inputs, you can either convert to Rec. 709 video, or to an ACES format like ACEScc — which is also log, but a different log.

Remember when I said log uses the same amount of data for each stop? That’s not entirely true with Apple Log. The darker stops are compressed a bit, to control noise. If you’re familiar with ACES, this makes Apple Log more similar to ACEScct than to ACEScc. Many colorists prefer working with ACEScct because of the way it handles shadows, so Apple is in good company here.
