Introduction
There is little doubt that the use of digital images in learning, teaching and research projects
is growing. Typical uses include: supporting lectures and other presentations; creating Web-
based instruction and creating digital image archives. Another advantage of digital images is
that they can be delivered on a variety of supports: PowerPoint, Web, image database, CD-
ROM and print. It is therefore important to be familiar with image digitisation processes in
order to obtain images that are ‘fit for purpose’.
This document shows you how to apply image enhancement techniques using Adobe
Photoshop CS2.
Prerequisites
This document assumes that you are familiar with the use of a computer keyboard and
mouse, Microsoft Windows-based products and the use of a Web browser such as Netscape
or Internet Explorer.
