So I realize that this is not for everyone, but I'm currently involved in trying to learn to edit in the linear OpenColorIO space, a 32-bit space that Adobe put into Photoshop beta about two years ago, and is now in the general release version. It is supposed to be the future of both video and still photo color management. I asked Google Gemini to give me a definition, and this is what it said:
Definition: OpenColorIO (OCIO) in Photography
OpenColorIO (OCIO) is a complete color management solution designed for high-fidelity imaging and visual effects. Unlike traditional ICC workflows that "bake in" color and contrast (gamma) early in the process, OCIO uses a Scene-Linear pipeline. This separates the mathematical data of the image (the "physics" of the light captured by the sensor) from how that data is displayed on a monitor or print (the "View Transform").
Why it matters for high-end editing:
Infinite Headroom: By working in a 32-bit floating-point environment like ACEScg, you avoid clipping highlights or crushing shadows that would otherwise be lost in standard 8-bit or 16-bit spaces.
Predictable Math: Adjustments like Exposure scale light mathematically, preserving color ratios and preventing the "digital look" often caused by standard Brightness or Contrast sliders.
The View Transform: It uses an Output Device Transform (ODT)—such as ACES 1.0 SDR-video—to map high-dynamic-range data to a standard monitor. This ensures your highlights roll off gracefully (like film) rather than hitting a hard digital ceiling.
In short, it’s a shift from editing "pixels" to editing "light," providing a level of control and dynamic range recovery that standard ICC-based color management cannot match.
I'm just wondering if anyone else has explored this feature (it is also incorporated into Affinity Photo) and will use it for their own still photos.
