Do you know what it does?

I see it but don't know how does it work or waht is it doing. Any one can explain please, and when do you use it?

I've been wondering about this myself....

Clarity in Lightroom

That was an interesting read. PaintShop Pro has had a similar adjustment for some time, but I have not been able to figure out exactly what it does.

darkens midtones and shadows, creates depth almost like shadows and highlights

It increases "local" contrast. (it increases the appearance of large-scale light-dark transitions)

It seems like it also sharpens a bit.

Effects like this (I think it's called "Clarify" in PSP) can be closely approximated by using high-radius Unsharp Mask. Try taking a dull, flat-looking landscape and apply the USM filter with (approximately) the following settings:
Amount: 15%
Radius: 60 pixels
Threshold: 0

Adjust the first two numbers up or down to get the effect you want (results will also vary with file size), but leave the TH at zero. Sometimes I apply the filter twice.

Clarity is doing a contrast adjustment. Sharpening also works by doing a contrast adjustment (so I understand), so you should see a sharpening effect.

it looks like a big dose of USM. That's about it...
