When/why would one save a picture in JPEG format versus, say, BMP?
A. Some programs, like word processors, require pictures to be of a certain image format if you wish to use them in a document. A format like JPEG is simply a good way to save a high quality picture in a relatively small file; JPEG is truly cross-platform. Q. What I print out is not the same color as what I see on my screen. Why is that? A. Computer monitors generally can create and display more colors than an ink-jet printer can for instance. Output that is very different from what is displayed on screen can indicate that a color management system was not available or not used. Color management systems are available to help with this problem. Many are built into operating systems like Microsoft Windows 95 software, Apple Macintosh OS, and Sun Solaris OS. Color management systems help to match what you see on your display with a particular output device by finding a common color gamut (range) in which both can work.
