IOW you you have never worked in LAB

nospam
i have, and quite a bit. lab is useful for certain tasks, but photo editing isn't one of them.

You have never noticed the ease of a color change in LAB, compared to making a similar color change in RGB.

YOu have never brought out color using LAB that could not easily be brought out in RGB.

you just don't know how to do it in rgb.

The above are "edge cases."

nospam
