In the
Photojojo e-mail that I got last night, there was a link to a tutorial on a post-processing effect that I'd never heard of before,
the Orton Effect. The basic theory of this effect is that it would put 2 pictures together, one in focus, one out of focus, and combined they create a kind of softened but sharp effect. This tutorial shows you how to do this in photoshop with a single picture.

The site that this tutorial is on,
PCIN.net has quite a few little digital photography tips and tricks on it as well as some very basic info, so it's worth a look.
