If you are learning photoshop and want to try some special effects, you will be pleased to know there are some great tutorials on the web. An example is this tutorial by "PSHERO" for a photo transfer edge effect. This was my first attempt at the technique and it was easy to follow his instructions. There were screen shots of every step, which was very helpful. I would advise printing off the tutorial so you don't have to keep switching screens as you learn.
Here are more tutorials by PSHERO.
