I've been trying to understand the difference between the brightness or value component (as part of HSB/HSV) and the luminance component (as part of LAB).
I've read this short article on xrite which claims that luminance is objectively measurable, while brightness is subjective.
From what I understand from the article, since luminance is measurable in candela/square meter, it's possible to get consistency across monitors that are properly calibrated. While brightness is measured in % and differs from monitor to monitor, so 70% brightness would be different across monitors, even if they were calibrated.
That said, is this the only difference? Specifically, do they have different effects on colors?
