I am really new to Photoshop CS5 and new to photo editing in general, but I guess I am learning pretty well. I shot in raw and man oh man if you don't you really, really have to try it. At first you don't think that, yeah, its not that much different. But when it comes to editing it makes ALL THE DIFFERENCE.
I adjusted the exposure, making the photo brighter by taking away some shadows. I messed with the brightness, barely slide down the contrast and added a little more saturation. And I'm done.
*Note I did all this in the Raw editor that comes up when you shot in Raw and simpy saved. I don't think that you can change the exposure on a JPEG. I could be wrong.*
