Scan handlers: 12 JPEG compression products that help you get a grip on large images
Article Abstract:
Color images are more commonly used in desktop publishing because prices of scanners are coming down and the quality of desktop separation software is better, but a problem with color technology has to do with file size. Color files tend to be very large, consuming many megabytes. Fortunately, a solution to this problem exists in the form of the proposed Joint Photographic Experts Group (JPEG) standard, which is a compression algorithm with a high compression ratio. Compression utilities, such as Stuffit for the Macintosh or PKZip for PCs, are already familiar to microcomputer owners, but typically offer a compression ratio of 2:1, or only about 50 percent. JPEG, which is a 'lossy' compression method (some image data is discarded in the compression process), can achieves ratios on the order of 25:1, still generating decompressed images that are difficult to distinguish from originals.

Muscle machines
Article Abstract:
The Apple Power Macintosh G3/400 employs the 400Mhz G3 processor and is the fastest performer in the Macintosh line. The $4,498 system includes 128MB of RAM, a 9GB hard drive and a 21-inch Studio display. The G3 offers easy access to internal slots and drive bays. Apple may be a bit premature in abandoning serial ports and SCSI because many peripherals will not work with this machine unless special adaptors are available. The $7,629 SGI 320 Visual Workstation is based on the 500MHz Pentium III processor and includes 256MB of RAM, a 9GB hard drive and an 18-inch flat-panel monitor. Performance is slightly faster than the G3, but the price may prove an inhibiting factor.

Desktop video: it's here, it's easy
Article Abstract:
The idea behind MacroMind's MediaMaker post-production software is to use the Mac interface to control external video decks: overlay and integrate sound, animation, and graphics from the Mac, then print to videotape. Testers of the product actually created a business videotape. MediaMaker offers an interface that is easily understood, but video production requires skills different from those common in the printing industry. Much hardware was needed in creating the video, including an encoder, a camcorder and VHS dec. Assembling the equipment was not easy, especially satisfying the cable requirements. MediaMaker receives high praise from both experts and novices.
