Nikon Digital Camera user manual Mode S Shutter-Priority Auto, Mode a Aperture-Priority Auto

Mode S (Shutter-Priority Auto)

In shutter-priority auto, you choose the shutter speed while the camera automatically selects the aperture that will produce the optimal exposure. Use slow shutter speeds to suggest motion by blurring moving subjects, fast shutter speeds to “freeze” motion.

To choose a shutter speed, rotate the command dial.

Mode 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) 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

t portraits to blur background details, long field depths in landscape photographs to bring the foreground and background into focus.

To choose an aperture, rotate the command dial (the maximum and minimum values for aperture vary with the lens used).
