Colour space: almost all of us are working on sRGB monitors (hopefully 100% sRGB). There’s only a few affordable 4K monitors which display even 90% AdobeRGB let alone ProPhoto RGB. So regardless of internal processing engine, we’ll only be ever able to see the sRGB version.
Theoretically I can see the math benefits of processing in a larger space.
Does anyone have some real world examples where processing a larger colour space ended up yielding richer images in sRGB? Keep in mind, I’m not looking for examples where processing and outputting in a wider space yielded richer images as that’s not an option yet for 95% of users. And that’s before we get to printing.
This is a serious question. My own experiments with AdobeRGB and and enhanced colour spaces about ten years ago ended with no visual benefit and bad colours when moving images between applications (Apple Aperture and Photoshop) and/or posting to the web. I was calibrating with basICColour and had quality monitors even then.
PS. Of course input in AdobeRGB, processing in AdobeRGB and viewing in AdobeRGB on an AdobeRGB 95% coverage monitor should yield richer colours. Even input in sRGB, processing in sRGB and viewing in sRGB on an AdobeRGB 95% coverage monitor should yield richer colours too - the monitor has better colours.
