This is the best I can manage:

The only time I ever use it is for really really noisy photos when I want to apply more noise reduction to the shadows than the highlights.

This is not related to your question, but is troubling ... your file is "untagged". When saving jpegs (either for web, or any other purpose) ALWAYS make sure the "embed profile" checkbox is checked.

Yeah, no, that's just a demonstration of bad raw processing. There's absolutely no need for luminosity selections in that example.

Go to Window>Character. In the Character panel, the "TT" icon (All caps) might be checked.

Well, for a quickie, first add a Levels layer and move the middle slider to about 1.25. Then add a Channel Mixer layer, check the "Monochrome" box, and enter +100/0/0/0 for the values. Change that layer's blend mode to "Overlay" then lower its opacity to your taste.

Only the background? I would have thought the foreground needs help too?

Oh, good. I was afraid it was some of that hair nonsense again. Yes, that might be plausible, although generally such methods aren't necessary when proper single raw processing is employed. Can you provide a link to the video?

Sorry Lisa, I can't discuss this here, because it's core stuff from my classes. PLEASE take the Raw Class without any further delay.

Phew! Thanks for letting me know.

Yes, but I'm very wary of this question, whenever it arises, because often people are asking because they've been badly misguided by some random nonsense article they've found on the internet. So ... why are you asking?

How did you go?

Oh, it's great! Well done.

Got it yet?

Ok, try it again. And again. Until it works.

And you double-clicked it, but no window opened?

That's right. Is that the eyedropper you used? The white one on the left?

Oh yeah, something's gone BADLY wrong there. Do her face swap again.

It's looking great.

You're making me nervous now. May I have 100% crops from Dad's and Mum's faces?

Yeah, the hard drive space issue is cause for concern. Brian always says you should have at least 1/3rd space free. You're well below that.

It would need to be blurred a bit.

I agree with Samantha. You need to be in the Levels dialog in your Properties panel, not the Masks dialog.
