Roger's job requires him to take pictures of apartment interiors. A wide-angle lens is best for taking these pictures. Roger bought a new camera with a wide-angle lens. He took the camera home. He read the manual. The manual said nothing about how to set up the wide-angle! He went back to the camera shop. He asked a worker how to set up the camera for wide-angle. The worker showed him. He said, "Go to Function. Set the camera on S. S is wide-angle. It also uses fewer pixels, so you can put your pictures online quickly." Roger went to four apartments. He took 43 pictures. He uploaded them to his office computer. Not a single picture was wide-angle. Roger asked a coworker for help. "Why is it on S? S stands for small!" she said. "You have to set the camera on W—W for Wide. It's so obvious!"
