Digicam file formats
By Jakob Jelling

Looking at the digital camera, a person can visualize it as
a combination of a camera along with a miniature computer system
that stores the images as files or sets of bits, rather than a
chemically treated film. Thus it comes to be a fact that there
are certain file formats in which these images of the
photographs captured by the camera are stored. And again, this
is subject of discussion for understanding the digital camera
properly. In this effort this discussion reveals the intricate
but overlying to provide a brief overview to the readers
regarding the file formats of the digital cameras.Basically,
strictly considering the facts, there are three file formats
used by digital cameras to create images of photographs taken by
them. These are JPEG, TIFF and RAW. These are the names of the
formats but like their strange names their identity remains in
the dark if these are not conversed in a little detail. The most
vastly and commonly used file format for digital cameras is the
JPEG file format. It is time and again the lone available file
format on primary and some intermediate standard digital
cameras. Many sophisticated digital cameras allows the users to
opt for between JPEG, TIFF and RAW. However professional
photographers usually prefer to shoot RAW. Yet the discretion
remains with the human preference only.
It is a fact that the acronym JPEG stands for "Joint
Photographic Expert Group" after the group that developed this
file type. To make things easier it must be clarified that JPEG
is a compression technique that can considerably trim down the
file size of a photograph and other unremitting tone images.
Almost all digital cameras have a number of JPEG compression
levels and quality settings to select from. The users can make
use of them as per discretion and the photograph taken. Thus the
jpeg images do not consume much space on a memory cards. Another
specialty of this digital camera file format is that JPEGs store
camera settings and scene information. All these advantages make
this file format so popular and diversely accepted.
The next digital camera file format is the TIFF (Tagged Image
File Format). This file format has the greater advantage that it
does not lose any image file information during the compression
process and moreover as a consequence it does take up a lot of
space from a memory card in comparison to a JPEG image. Due to
this detailed storage it also takes additional time to retrieve
the information to the card. Basically the TIFF compression
reduces images to about one-third their original size as per
convention.
Coming to the next digital camera file format. It is defined
as the RAW file! It is also sometimes referred to as an
appropriate digital negative. Most advanced digital cameras
allow or permit the ability to shoot RAW in professional
standards. The interesting portion is that in a RAW image no
alterations are made by the camera (such as sharpening or white
balance). And this gives entire control to the photographer when
he or she processes an image later. However this RAW file format
is not used extensive due to the fact that most image editors
cannot open it and computer-processing time is also more.
However the fact still remains that a RAW image has a smaller
file size than a TIFF.
With all these discussions regarding the different digital
camera file formats, it is clear that the three most widely
accepted file formats have their own advantages and
disadvantages, yet they are unique in some way or the other that
makes them special in their own manner. The knowledge about
these digital camera file formats of storage not only yields
greater understanding of the camera; it also opens the eyes
towards the fantastic results of technological advancements in
our daily lives.
