I am a bit surprised that you recommend Beta-RGB as the working space. I
thought the ideal working space would be the camera-own profile? and next
best ProPhoto? But maybe your suggested reading will answer this question
along the line.
The well-behaved camera profile RGB working space - that you get when you
follow my tutorial for making a camera input profile - has important uses
such as retrieving channel information as captured by the camera and for
bringing colors into gamut with respect to a chosen RGB working space. But I
don't use my camera input profile color spaces for extended image editing -
for one thing there are too many imaginary colors.
A linear gamma version of BetaRGB makes an excellent working space (you can
easily make such using PhotoShop, at least you could with CS2). But the
copyright on the BetaRGB color space seems a bit restrictive.
You could try a linear gamma version of the Rec.2020 color space (a Rec.2020
profile is included with ArgyllCMS), which is what I currently use for image
editing, though I'm thinking about switching to using the ACEcg primaries.
This article has interesting take regarding the various color spaces:
