Photoshop is a graphics based program created with images known as raster graphics.
Other graphic applications, i.e. Illustrator, Corel Draw and Freehand, create vector
graphics. Vector graphics are composed of solid lines, curves and other geometric shapes
that are defined by a set of mathematical instructions. Vector images work best for type
and other shapes that require clear crisp boundaries. Raster images work best with
photographs. Raster graphics are comprised of a raster (a grid) of small squares called
pixels. Objects in Photoshop are groups of many pixels – each of which can be a
different color. Raster images require more memory and storage than vector images.
Photoshop is a memory-hungry program.
