Basic Terminologies
Many people find digital cameras difficult to
understand mainly because of the technical terminologies involved.
There are a lot of terms associated with digicams, however it is
good enough to know just the basic terms before getting your hand
on digital cameras. The basic terminologies of digital cameras are
pixels, white balance, pixel count, and aspect ratio.
Pixels:
Pixel is the abbreviated form of the term Picture Element. Even
though digital images look continuous like a motion picture, it is
actually composed of numerous tiny squares referred to as Pixels.
Each pixel is made up of 3 channels, red, blue and green, and each
of the channels have a value between 0 and 255.
Pixel Count:
The Pixel count is the measurement based on which the manufacturers
categorize digital cameras. Pixel count is the number of individual
pixels constituting the composition of the entire image. A million
pixel is shortened as 1MP (Mega Pixel), so a 3MP camera will
generate picture with 2 Million Pixels. Currently Cameras are
available in the range of 1MP to 14MP. The pixel count is choose photos to be
used for photo books. The photos can be processed into a picture book with the
software that is available on

charge.
Aspect Ratio
The Aspect Ration refers to the ration of the length of the sides
of the image generated by the camera. Some digital cameras use the
same aspect ratio of their film counterparts, but consumer grade
digicams use a 4:3 aspect ratio since most video monitors use a 4:3
ratio.
White Balance
White balance is a setting that is used to remove unrealistic color
manifestation in the image so that a white object appears white in
the final image and not yellow or blue. Some digital cameras
automatically decide the white balance to be used for a particular
lighting and there are others with group of settings specific for
different lighting. IN the most advanced cases, manual settings is
enabled where you focus the camera on a white card and let the
camera manipulate the settings to make the card appear white.
Memory
The digital camera memory is one of the most important facets of a
digital camera, as the photographs taken are stored in this part of
the camera. There are many types of memory employed in digicams,
understanding them is essential to have control over the
digicam.
