I have sort of a before and after project im tinkering around with in photoshop. I started with the same pic and made a copy of it to actually work on. I'm trying to find an easy way to select the same portion of the photo in both pics as sort of a before and after comparison.

Using CS2, I'm sure the answer is right in front of me but like the subject line says..... i'm a photoshop noob.
