I came across a cool website today that illustrates and shows real life examples of people that suck at Photoshop. It is amazing that there are so many bad Photoshop users in the production world. Guess that is what happens when you hire a layout artist and not a graphic artist or designer. You will surely get a chuckle out of this if you are as big of a Photoshop nerd as I am.
