[argyllcms] Re: sRGB/AdobeRGB98 vs Lab (was Verifying profile quality...)



What happens if you redrew the gamut to also limit the maximum energy at any hue to something like the maximum typical brightness of an LCD? (Say 250 cd/m2) knowing full well that this would only happen in practice if you did something like discussed below? 

Not sure. You'd have to pick a white point brightness, and the gamut
would depend on the two numbers you've picked, making it a
non absolute boundary (and therefor disappointing to those who would
like to know what the "speed of light" is).

I still think that would be more useful in a practical day-to-day sense.


It stops working if you aren't adapted to the lower brightness white point.

I think we are in agreement then...you couldn't just plonk down white at 125 cd/m2 sitting near to green at 250 cd/m2 and expect that the eye will 'believe' that the white is white and not a boring grey. But if you used subtle amounts of extra energy here and there the eye could be fooled....giving you a wider gamut.


Right, so it might be possible to experiment with this idea in that manner.


Well, even at 8 bits it would be interesting to try. So how do you suggest we make a profile and LUT that does it?
