shadow The darkest part of an image, represented on a digital image by pixels with low numeric values.

sharpening Increasing the apparent sharpness of an image by boosting the contrast between adjacent pixels that form an edge.

Shooting menu The D7000’s list of settings and options that deal with how the cam- era behaves as you take pictures, such as image size and quality, white balance, auto- focus settings, ISO sensitivity, or movie shooting options. See also Playback menu, Retouch menu, and Setup menu.

shutter In a conventional film camera, the shutter is a mechanism consisting of blades, a curtain, a plate, or some other movable cover that controls the time during which light reaches the film. Digital cameras can use both a mechanical shutter and an electronic shutter for higher effective speeds.

Shutter-priorityAn exposure mode in which you set the shutter speed and the cam- era determines the appropriate f/stop. See also Aperture-priority.

side lighting Applying illumination from the left or right sides of the camera. See also backlighting and front lighting.

Single-servo autofocus An automatic focusing setting (AF-S) in which the camera focuses once when the shutter release is pressed down halfway. See also Continuous- servo autofocus.

slave unit An accessory flash unit that supplements the main flash, usually triggered electronically when the slave senses the light output by the main unit, or through infrared or radio waves.

slow sync An electronic flash synchronizing method that uses a slow shutter speed so that ambient light is recorded by the camera in addition to the electronic flash illumi- nation. This allows the background to receive more exposure for a more realistic effect.

specular highlight Bright spots in an image caused by reflection of light sources.

Spot meter An exposure system that concentrates on a small area in the image. See also Center-weighted meter and Matrix metering.

time exposure A picture taken by leaving the shutter open for a long period, usually more than one second. The camera is generally locked down with a tripod to prevent blur during the long exposure. The D7000 can automatically shoot time exposures up to 30 seconds, as well as much longer exposures with the camera set to Bulb and the shutter opened/closed manually.
