A simple technique professional photographers use to ensure they properly
expose their pictures, especially in challenging lighting situations. When AEB is
selected, the camera automatically takes three or more shots with a different
exposure for each frame.
Autofocus refers to a camera lens' ability to adjust its configuration in order to
focus properly on a subject regardless of whether it is near or far from the
camera. Autofocus lenses generally provide vastly superior image quality than
do their fixed focus cousins since they do not have to rely on their depth of field.
Also known as: "AF", "auto-focus"
An end-user created object that is used to logically group data objects according
to some user-defined criteria. An album may or may not be a physical folder in a
filesystem.
A circuit that converts an analog signal, having a continuously varying amplitude,
to a digitally quantized representation using binary output signals.
Usually refer to image aspect ratio or pixel aspect ratio.
Image aspect ratio: The ratio of the image width to the image height.
Pixel aspect ratio: The ratio of the distance between sampling points in the two
orthogonal sampling directions. If the distances are equal, the pixel aspect ratio
equals 1:1 and is said to be "square."
With auto white balance, the camera attempts to determine the color
temperature of the light and automatically adjust for that color temperature. Many
people just leave the camera set to auto white balance all the time.
A type of silicon integrated circuit used to convert light into an electronic signal.
Usually refer to image compression or sound file compression.
Image compression: A process that alters the way digital image data are
encoded in order to reduce the size of an image file.
Sound file compression: A process of altering the sound data coding in order
to reduce the size of a sound file in the electronic still picture camera.
A transport-provided logical or physical persistent mechanism for transferring
data between devices.
A standardized ASCII file created in a digital camera and stored on removable
media along with the image files that indicate how many copies of which images
should be printed. It also allows index prints, cropping, and text overlays to be
specified.
