Aperture Priority Shooting - Olympus E-620 Instruction Manual

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. When you close the aperture (increase the aperture value), the camera will
focus within a longer range. Use this mode when you wish to add changes to the background
representation.
