Keep the Background Sharp

When you focus on your main subject close to the camera, the background is some times blurry and out of sharp focus. To create an image in which the background is as sharp as the foreground, you need to adjust the camera's aperture. Using a big f/stop number, such as f/22, helps make the background appear crisp. Using a small f/stop number, like f/4, would make the background appear soft and out of focus.
