b. What Photoshop is used for/what it is not used for
(raster vs. vector graphics)
Raster graphics- pixel driven pictures that have a set
resolution. The pictures are rendered on the screen one
pixel at a time to reproduce the image. This is excellent
for digital photography, and some scanned images. Still
pictures that might need color correction and printing
are what Photoshop excels at. Some artists do actually
draw in Photoshop and create incredibly realistic images
that look as if they are digital photos. Bert Monroy is an
example of that type of artist and designer. His work can
be found at: http://www.bertmonroy.com
Vector graphics-
mathematical representations of the
lines and curves in an image. Vector graphic programs
are used to create logos and graphics that need to be
resolution independent. They can be scaled to any size,
shape, or proportion without losing their sharpness and
resolution. Adobe Illustrator is generally the vector
drawing software of choice for professional graphic
designers.
c. Where Photoshop stands in the Graphic Design world
today
The current version of Photoshop is the CS4 or Creative
Suite 4 version which corresponds to version 11 in
Photoshop’s history dating back to the late 1980s early
1990s. With each version improvements in the tools and
workflow, added features and filters and more
possibilities open up. The current version of Photoshop
CS4 is continuing to branch into the 3D world and has
added a video editing component. So Photoshop has
grown beyond merely editing still images.
d. Other Photoshop software

Photoshop.
Photoshop Lightroom- digital photo editing and
management software.
