A : Aperture priority shooting
The camera sets the optimum shutter speed automatically for the aperture value you
have selected. When you decrease the aperture value (F-number), the camera will
focus within a shorter range (shallow depth of field) and produce a picture with a blurred
background. Conversely, when you 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.
