Shooting; Aperture-Priority Auto Exposure Mode - Nikon FM3A Instruction Manual

Shooting: Aperture-Priority Auto Exposure Mode
Tips
• The aperture setting lets you adjust the exposure and control the depth of field.
... If the subject of your picture extends into the distance and/or you want the entire
subject to be sharp, choose a narrow aperture setting. If you want an out-of-
focus background and/or foreground, select a wide aperture i. e. f/2.8. If your
subject has little or no depth of field, such as flat wall, choose an intermediate
aperture setting.
• In Aperture-Priority Auto Exposure mode, you can make the aperture setting as
desired, and the camera controls the shutter speed automatically.
