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.
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.
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. Alternatively, use a tripod or the OIS function to
stabilize the camera.
Cloud Computing
Cloud computing is a technology that allows you to store data on
remote servers and to use them from a device with internet access.
Color space
The range of colors that the camera can see.
Color temperature
Color Temperature is a measurement in degrees Kelvin (K) that indicates
the hue of a specific type of light source. As the color temperature
increases, the color of the light source has a more bluish quality. As the
color temperature decreases, the color of the light source has a more
reddish quality. At 5,500 degrees Kelvin, the color of the light source is
similar to the sun at midday.
