More on Photography Choosing an exposure mode: 40 A: Aperture-Priority Auto In aperture-priority auto, aperture is controlled by rotating the command dial; shutter speed is set automatically by the camera in response to lighting conditions. Aperture varies in increments equivalent to 1/3 EV (1/3 step); depending on the zoom position, the camera can achieve apertures as large as f/2.8 or as small as f/8. Rotate command dial until desired aperture appears in control panel and 8M shooting display. 1/60 F8.0 15 If the selected aperture would result in the picture being under- or over-exposed, the aperture display in the monitor or electronic viewfinder will flash when the shutter-release button is pressed halfway. Choose another aperture and try again. An aperture of f/8 may not be available at some zoom positions. For smaller apertures, try zooming the camera out. Aperture and Zoom The maximum and minimum values for aperture are determined by the camera lens and zoom setting. Unless On is chosen for Zoom options > Fixed aperture ( 95), aperture will change as the camera is zoomed in or out. If the second-highest aperture setting is selected with the camera zoomed all the way out and the camera is then zoomed in, the camera will vary the f/-number to maintain aperture at the second-highest setting for the current zoom position. Faster Shutter Speeds Depending on the amount of light available, it may be possible to achieve shutter speeds as high as ¼,000 s (1/8,000 s when shooting in Ultra HS) by zooming the camera all the way out and selecting the smallest aperture (largest f/-number). 43
