When I sat down to begin writing a tutorial for my four favorite image sharpening techniques, I realized about halfway through my first one that I was going to need to split them up. Otherwise I would risk having a post so long nobody would finish reading it. So now, having finally completed them all, we have my four favorite Photoshop sharpening techniques.

1. High Pass Sharpen
This is my favorite, and possibly the most flexible of the four. I nearly always use this sharpen, and often use another alongside it.

2. Luko USM
This sharpen is good for adding a little contrast back in to an image, where others sometimes diminish it. Very useful, especially in landscapes or portraits.

3. Adamus Sharpen
This sharpen is great, but does not translate to print very well at all. Best as a web only solution. Click the image for a full size view.

4. LAB USM
This is a subtle sharpen, that helps diminish the haloing that can occur with normal Unsharp Mask. Click the image for a full size view.
