The focus of this paper is the portable handheld digital camera for still imaging. Digital images have multiple uses such as in computer applications like printed documents and presentations. Ease of duplication is another advantage of digital photography. Prints and computer files can be copied indefinitely at very low cost. In addition, savings result from never needing film or developing.
Space is saved because images are stored in digital form.
Prints are created using standard computer and printer hardware with no additional equipment needed. Image appearance and quality are easily controlled using software included with cameras. For some situations, digital cameras are at a disadvantage compared to print and slide film cameras. For computer use, digital camera image quality is close to standard VGA quality. Further disadvantages concern convenience, because digital photography requires the user to do all processing work.
