Glossary
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 a zoom lens 
(Optical zoom). When using the Digital zoom, the image quality will deteriorate as 
the magnification increases.
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.
