On top of that, in your example you have a nice and sharp distinction between what you do want to adjust, and what should stay the same. But for example with different shades in the face, you don't have that luxury, it takes some more creativity than drawing a straight line.
Please understand that my tutorial is not about Quick Mask per se, rather about the selection-to-mask route as a whole. So I didn't dwell on that manner in which I'd made my selection in the example.
However, I can tell you that was made with a big soft brush, so my subsequent adjustment bled into the sky a little. The fact that you can't tell that it has done so is testament to the value of the method.
It is a common trait of new Photoshoppers, I believe, that they try to mask with much too much precision. With my example photo, a new user would almost certainly try to use any means available to make a sharp, accurate selection of the grass area - whether it be with lasso, magic wand, or Quick Mask with a small/hard brush.
A more experienced operator knows that one broad sweep with a big soft brush in Quick Mask will achieve excellent results, in a fraction of the time.
When you've made as many millions of selections as I have, you'll know what I mean.
