: Aperture priority shooting
The camera sets the optimum shutter speed automatically for the aperture
value you have selected. When you open the aperture (decrease the aperture
value), the camera will focus within a shorter range (shallow depth of field) and
produce a picture with a blurred background. Conversely, when you close the
aperture (increase the aperture value), the camera will focus over a wider
range in the forward and backward directions (more depth of field), producing
a picture with clear focus throughout the image area. Before shooting, you can
use the preview function to check how the background will look in your picture.
