I see a lot of folks convert to the LAB color space (and back again) and you most often say you're doing it so you can edit luminance and color informaton separately.
My question is, why not use the HSL color space instead? It seems more intuitive. Photoshop has the Hue, Saturation and Luminosity (Luminance and Luminosity are very similar) blend modes, so you can extract HSL channels and do your HSL modifications interactively within an RGB image--no need to switch modes.
I understand all about how the LAB color gamut covers the whole range of human color perception and then some, but this capability isn't of much use unless you have a display device to match.
My inquiring mind wants to know.
