Really curious how this works under the hood!

  I’ll open source this feature and do a write up this week. But as a hint, it involves some internal SkyLight.framework and Core Brightness APIs to ramp up the headroom slowly. Here’s my previous failed attempt: https://alinpanaitiu.com/blog/over-500nits-failed/ https://alinpanaitiu.com/blog/over-500nits-failed/

    Ah so it's not taking screenshots continuously and rendering them into an HDR video?
    • alin23 5y ago
      Definitely not :) It's changing the real nits limit of the screen, with the same APIs that the system uses when a HDR video is played.

        Congrats! That's really impressive work.
