8-bit, 12-bit, 16-bit See Bit depth.
Accessory shoe See Hotshoe.
Aperture The lens opening which admits
light. Relative aperture sizes are expressed
in f-numbers (see below).
Artefact Occurs when data or data
produced by the sensor is interpreted
incorrectly, resulting in visible flaws in
the image.
Bit depth The amount of information
recorded for each color channel.
8-bit, for example, means that the
data distinguishes 28 or 256 levels of
brightness for each channel. 16-bit
images recognize over 65,000 levels per
channel, which allows greater freedom
in editing. The D5300 records RAW
images in 12- or 14-bit depth and they
are converted to 16-bit on import to
the computer.
Bracketing Taking a number of otherwise
identical shots in which just one
parameter (e.g. exposure) is varied.
Buffer On-board memory that holds
images until they can be written to
the memory card.
Burst A number of frames shot in quick
succession. The maximum burst size is
limited by buffer capacity.
Channel The D5300, like other digital
devices, records data for three separate
color channels. See RGB.
Chimping Checking images on the screen
after shooting.
CCD (charge-coupled device) A type
of image sensor used in many digital
cameras.
Class (or speed class) rating A measure of
the performance of memory cards. Class
rating is most important when shooting
video. See also Speed rating.
Clipping Complete loss of detail in
highlight or shadow areas of the image
(sometimes both), leaving them as blank
white or black.
CMOS (Complementary Metal Oxide
Semiconductor) A type of image sensor
used in many digital cameras, including
the D5300.
Color temperature The color of light,
expressed in degrees Kelvin (K).
Confusingly, “cool” (bluer) light has a
higher color temperature than “warm”
(red) light.
CPU (Central Processing Unit) A small
computer in the camera (also found in
many lenses) that controls most or all
of the unit’s functions.
Crop factor See Focal length multiplication
factor.
Diopter Unit expressing the power of a lens.
dpi (dots per inch) A measure of
resolution: should strictly be applied only
to printers. See also ppi.
Dynamic range The range of brightness
from shadows to highlights within which
the camera can record detail.
Exposure Used in several senses. For
instance, “an exposure” is virtually
