Demo photos
The photos are composed specifically to show off the camera's capabilities. For example, I'd be unlikely to take a picture of a basketball game and want the chain link fence to be in focus.
If I wanted to take a picture with everything in focus I'd use a very small aperture. But sometimes I want a part of a picture to stand out by being in focus. Being able to do my photo composition sitting at my desk instead of fumbing with my camera would be great.
