Hyperfocal distance
The closest point upon which a photographer can focus where depth of field is
infinity. When the lens is focused for hyperfocal distance, the deepest depth of
field, covering from 1/2 the hyperfocal distance to infinity, can be obtained at each
f/stop. The longer the focal length, the longer the hyperfocal distance; the smaller
the aperture (the larger the f/number), the shorter the hyperfocal distance.
ISO
The international standard for representing film sensitivity. The higher the number,
the greater the sensitivity, and vice versa. For example, ISO 200 is twice as
sensitive as ISO 100, and half as sensitive as ISO 400. When you change the ISO
setting on your camera, you adjust the sensitivity of the imager equivalent to the
corresponding film sensitivity.
JPEG
A compressed image file format with a color space that is understood by all
applications including Photoshop. This format was developed by the Joint
Photographic Experts Group.
Matrix Metering system
This advanced light metering system using multi-segment sensor and computer is
available in the DCS 330 camera.
3D Matrix metering (DCS 330 only) is performed when your camera is used with
D-type AF Nikkor lenses.
Rear-Curtain Sync
Flash fires an instant before the second (rear) curtain of the focal plane shutter
begins to move. When slow shutter speeds are used, this feature can create a blur
effect using ambient light, i.e., the exposure traces flowing light following a
moving subject, and the subject’s movement is frozen at the end of the trial of light.
(See also Front-Curtain Sync.)
Single Servo AF
Once the subject is in focus, focus is locked. This is useful when recomposing the
picture. For Single Servo AF, focus-priority is given so the shutter cannot be
released until the subject comes into focus.
