Photoshop is intense if you don't have the work-flow down. If you are a photographer and you can pick only one of those two programs definitely go with Lightroom. What version of Photoshop do you have? I was going to cover Photobucket editing techniques since that's what most people have on this forum but I can help you with Photoshop. We can meet in a chatroom and I can walk you through a good basic photo-editing technique in about 45 mins. After that, I can point you toward some free online tutorials that will walk you through intermediate and advanced techniques. Just opening a shot in Photoshop is difficult if you don't know the steps.
How's the camera search coming along?
