Digital imaging is the hottest topic. No matter what it is for, without understanding its application before getting any equipment or service may be a useless investment.

The major usage of digital imaging covers Image Bank, Presentation, Broadcasting, email, electronic color separation for printing etc. These application will make use of the fast communication technology or the computerised process to benefit in efficiency, achievement or profit.

Before any planning, one must get all information, especially the software and hardware cost and the requirement. Due to different set up to meet different need, the right choice may never be the same. Otherwise, one may lose all instead of any expectation. For example, one might spend thousands to get a digital camera, with so called million pixel, but it could only print up to a 3R size inkjet. What a pity! There are a lot of misconception, including whether a personal film scanner will meet all usage, the resolution of image will meet all kind of output etc.
