Shooting with Aperture priority

If you set the aperture (a smaller F- number) wider, the in-focus range becomes narrower. Only the main subject is then in focus. When the aperture is smaller (a larger F-number), the in-focus range becomes wider. The whole image is sharpened. The shutter speed is automatically adjusted.
