How To Sharpen in Photoshop

In this very interesting video, SLRLounge contributor Lauri Laukkanen is going to show us three different techniques to increase the sharpness of an image in Photoshop.
Personally I prefer the first one (and I guess is the same for Lauri), but I use slightly different settings, like I stay between 1 and 2 in the High Pass Filter, and then I used Overlay, but at the end the result is the same.
