I've been a little bit obsessed with faded/older looking photos lately and I found some pretty awesome photoshop/photoshop elements actions online recently.
As a photoshop elements user I can feel pretty ignored by most blogs that talk about these sorts of things, so I was pretty stoked to find a whole blog full of PSE actions (that are free too).
If you have PS or PSE I definitely recommend checking out the blog Coffee Shop. I posted specific examples of some of the different actions here as part of my "Lessons in Photography Class" series as well in case you want more information.
It's really amazing what a few button pushes can do.
