Taking Photographs—Exposure

M: Manual

In manual exposure mode, you control both shutter speed and aperture. Shutter speed can be set to values between 30 s and 1 8,000 s, or the shutter

can be held open indefinitely for a long time-exposure (). Aperture can be set to values between the minimum and maximum values for the lens. Using the electronic analog exposure display in the viewfinder, you can adjust exposure according to shooting conditions and the task at hand.

To take photographs in manual exposure mode:

1 Press the button and rotate the main command dial until M is displayed in the view- finder and top control panel.

2 Rotate the main command dial to choose a shutter speed, and the sub- command dial to set aperture. Check exposure in the electronic analog exposure displays (see right), and continue to adjust shutter speed and aperture until the desired exposure is achieved.

3 Frame a photograph, focus, and shoot.

Long Time-Exposures

At a shutter speed of, the shutter will remain open while the shutter-release button is held down. Nikon recommends using a fully-charged EN-EL4 battery or an optional EH-6 AC adapter to prevent loss of power while the shutter is open. Note that if the shutter is open for more than approximately ½ s at any setting, “noise” in the form of randomly-spaced, brightly-colored pixels may appear in the final photograph.

Provided that an external exposure meter is used, the exposure ratio need only be taken into account when the lens aperture ring is used to set aperture.
