I see they say that Unsharp Mask did that, eh? Huh.
Not by itself it didn't. Try this:
Take the original photo, put into Photoshop, Filter, Sharpen, Unsharp Mask and set the following:
Amount 183%
Radius 5.2 pixels
Threshold 42 levels
Reduce the image to 180x142 so it's the same size as the altered one.
Copy in the unaltered one again and compare all three of them.
In the one just changed, the entire photo is sharper, but there are areas that Unsharp definitely made lighter. Those areas are the lips, eyes and earrings.
The AP altered one has also been sharpened and lightened, but the eyes are white -- WAY lighter than the lips. It's NOT balanced and Unsharp does not work that way. Definitely not.
Those eyes were changed separately and deliberately.
Just my 2 cents
Oh, and I think my alteration looks much better than APs. Mine just makes her look pissed off
