Digital images are the pictures that "live" on your computer monitor. They can look like traditional photographs, illustrations, cartoons, charts and graphs, logos (the Excellence Seal in the upper left corner), etc. Even words can be digital images, such as the title above, and the navigation button names in the toolbar on the left side of this Web page. In reality, they all consist of digital information that is arranged into data files which various software applications decode into the images that we see on screen or printed out. These digital image file types have specific attributes which make them more or less appropriate when used for different outputs ... whether they are ONLY seen on a computer screen, as in the case of Web images, or if they are to be printed out from high to low end printing devices and depending on what media they are output to; paper, transparency material or film ... all of these can help the user determine the "best" digital image file type to employ.
This set of modules is designed to help the new user of digital images to become familiar with the minimum requirements and suggested file types for various end products and outputs.
