Aspen Yellow and Monitor Gamut

[Downrigger]

I had a go from an analytical point of view... Differences are subtle.

Instructive for me, Ted. Your solution approaches my recollection surely more than mine. Thank you. Major learning for me in understanding I need more facility with color curves when I get into this sort of fix. I will keep that site handy, too.

Good luck with bigger gamuts but I feel it's a red herring. Mainly of use for prints where the dynamic range is rather limited. I know of one aRGB colour that causes sRGB a lot of grief - a shade of teal. I ran aRGB test colours through my colorimeter.

I agree, John. In my preceding post, I forgot to mention that while editing, the saturation was quite a bit below 100% and that maybe the bigger problem in the OP image was a hue shift towards red. Based on that, I would have been inclined to take the hue to maybe 55 degs and cut back on the blue for a little more saturation but not enough to significantly reduce the lightness.

It's easy to get confused between "lightness" and "brightness" in the world of color- hopefully we all know the difference, eh?

As to sRGB, one little-known piece of trivia is that the well-respected MacBeth card's cyan patch is actually out-of-gamut in sRGB!

A raw converter uses a camera profile just as it's internal jpg engine in the camera does. It scales r g b values and produces something suitable for viewing rather than just providing the linear data from the sensor. It's a little like gamma being added to images that are to be displayed.

Good luck with bigger gamuts but I feel it's a red herring.

Right, John - I do use profiles when processing in LR, (it's my first step after setting exposure overall) more and more using profiles generated with x-rite color checker rather than the standard collection in the software. I wish I'd done that for this image - I'd be interested to know how doing so might have changed my sense of fidelity.

You may be right about the "red herring", but it's a sophisticated way for me to blame the equipment!

I want to calibrate my cameras but of late it seems they can have colour temperature correction information in them as well - more web research on just how that is done is needed.

I still think you should post the raw on filebin ( there as it doesn't need registering etc) and let others have a go at it. I suspect the fix for some will be easy - not me but I enjoy trying.
