A: Aperture-Priority Auto In aperture-priority auto, you choose the aperture while the camera automatically selects the shutter speed that will produce the optimal exposure. Large apertures (low f-numbers) increase flash range (0 147) and reduce depth of field, blurring objects behind and in front of the main subject. Small apertures (high f-numbers) increase depth of field, bringing out details in the background and foreground. Short field depths are generally used in portraits to blur background details, long field depths in landscape photographs to bring the foreground and background into focus. Large aperture (f/5.6) Small aperture (f/22) To choose an aperture between the minimum and maximum values for the lens, rotate the sub- # command dial while the exposure meters are on. Sub-command dial A Depth-of-Field Preview To preview the effects of aperture, press and hold the depth-of-field preview button. The lens will be stopped down to the aperture value selected by the camera (modes P and S) or the value chosen by the user (modes A and M), allowing depth of field to be previewed in the viewfinder. Depth-of-field preview button A Custom Setting e5-Modeling Flash This setting controls whether the built-in flash and optional flash units such as the SB-910, SB-900, SB-800, SB-700, and SB-600 (0 293) will emit a modeling flash when the depth-offield preview button is pressed.
