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.
