Glossary
ACB (Auto Contrast Balance)
This feature automatically improves the contrast of your images when
the subject is backlit or when there is a high contrast between your
subject and the background.
AEB (Auto Exposure Bracket)
This feature automatically captures several images at different
exposures to help you capture a properly-exposed image.
AF (Auto Focus)
A system that automatically focuses the camera lens on the subject.
Your camera uses the contrast to focus automatically.
Aperture
The aperture controls the amount of light that reaches the camera’s
sensor.
Camera shake (Blur)
If the camera is moved while the shutter is open, the entire image may
appear blurred. This occurs more often when the shutter speed is slow.
Prevent camera shake by raising the sensitivity, using the flash, or using
a faster shutter speed. Alternately, use a tripod, the DIS or OIS function
to stabilize the camera.
Composition
Composition in photography means arranging objects in a photo.
Usually, abiding by the rule of thirds leads to a good composition.
DCF (Design rule for Camera File system)
A specification to define a file format and file system for digital cameras
created by the Japan Electronics and Information Technology Industries
Association (JEITA).
Depth of field
The distance between the nearest and farthest points that can be
acceptably focused in a photograph. Depth of field varies with lens
aperture, focal length, and distance from the camera to the subject.
Selecting a smaller aperture, for example, will increase the depth of field
and blur the background of a composition.
Digital zoom
A feature that artificially increases the amount of zoom available with
zoom lens (optical zoom). When using the digital zoom, the image
quality will deteriorate as the magnification increases.
DPOF (Digital Print Order Format)
A format for writing printing information, such as selected images
and number of prints, on a memory card. DPOF-compatible printers,
sometimes available at photo shops, can read the information from the
card for convenient printing.
EV (Exposure Value)
All the combinations of the camera’s shutter speed and lens aperture
that result in the same exposure.
