Digital Imaging

Digital images can be created by a variety of input devices and techniques, such as digital cameras, scanners  and more. 

Digital image editing is the process of altering digital images, whether they be digital photographs or other types of digitally represented images.

Specialised software programs called vector graphics editors are the primary tools with which a user may manipulate, enhance, and transform images.

Publishing

Desktop publishing combines a personal computer, page layout software and a printer to create publications on a small economic scale. Users create page layouts with text, graphics, photos and other visual elements using desktop publishing software such as  Adobe InDesign and Adobe Photoshop.
DTP started in 1985 with the introduction of Aldus Pagemaker software and the Apple LaserWriter printer for the Apple Macintosh computer. The ability to create WYSIWYG page layouts on screen and then print pages at 300 ppi resolution was revolutionary.
