Definitions
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.
Auto focus 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. Auto focus 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 file system.
A circuit that converts an analog signal, having a continuously
varying amplitude, to a digitally quantized representation using
binary output signals.
cf. image aspect ratio, pixel aspect ratio.
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.
The process of encoding information using fewer bits cf. image
compression, sound file compression.
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.
