The best acne treatment is still post processing with either Picasa 3’s retouch tool or Adobe Photoshop’s clone tool 🙂
I have friends from all over who really like having their pictures taken, I’m sure you do as well. When the person typically has a smooth complexion and then grew a zit overnight, it’s easy to magic it away with post processing. I don’t consider that cheating, since most of the time the person does have flawless skin. Digitally removing a pimple from a photo taken of that person is actually restoring that person’s face as we usually know it.
