Some still hold the opinion that graphics and art is a mind thing and one
cannot become a graphics artist just by tweaking some shots in a
computer. Creativity may still be elusive but there is little doubt that
computer generated imagery and graphics have taken art to a new level.
With the availability of new and better graphics tools an artist has more
time to do things which he does best ......creating . It used to be
domain of Mac's, high end graphics workstations with the whiz kids
hunched on its big impressive screen. But soon a slew of PC based
graphics suites hit the market, turning every kid into a master
craftsman. Adobe Photoshop may be considered to be a pioneer in this
field. Corel's Photopaint and Paint Shop Pro were and are being used
widely even today. Windows based graphics software has made computer
graphics accessible to the common man. With the advent of digital
cameras, need for enhancing and improving family photos has lead to
phenomenal growth of home grown studios. The pace has quickened with
cameras mounted on mobile phones. The number of formats for graphics
files has also increased with the times. Starting with the humble bit map
file, bmp other popular formats are JPEG, TIFF, GIF and TARGA (.tga).<br>

Adobe Photoshop<br>

<br>

The field of computer graphics would not be complete without the mention
of Adobe Photoshop. In fact, it can be considered as the Microsoft
windows of the graphics world. The Photoshop tools make retouching,
manipulation and color correction possible within a few minutes as
compared to many days used by professional photographers using
traditional tools. Photoshop uses its own native format .psd for storing
files. The layer information can be preserved in this format, permitting
the user to effect changes at a later date. However the native format
.psd gives rise to large and heavy files which are rather difficult to
transfer to other computers. Photoshop can also work with several other
graphics file formats like BMP, JPEG, and Gif etc. It is also capable of
importing vector graphics. In the latest version, it is also possible to
work on several digital camera formats making it easy for home users to
manipulate digital images.<br>

<br>

Along with several other Adobe software, Photoshop can be used to create
images not only for the print media but also for the internet, animation
and motion pictures.<br>

<br>
An important feature of Photoshop is the plug-ins. With plug-ins the
capability of Photoshop is extended phenomenally. In fact, a sub culture
or mini world has developed under the umbrella of plug-ins. Effects such
as grain, lens flare, degauss etc. are quite popular. Color correction
and manipulation is an important feature of Photoshop, lending magic to
real world images.<br>

Adobe Photoshop software is a pioneer in the field of computer graphics.
It is moderately priced and is suitable for manipulating high resolution
graphics. It can convert into a variety of graphics formats which are
suited both for the print as well as   web-sites.</p>        <!--
