The amount of on-screen time allotted to each image before going on to the next can be altered by individual viewers. The folder was then closed and compressed into a single unit using the Aladdin Systems Inc. shareware application, DropStuff. This process, along with the JPEG compression scheme, makes it quicker to send digital information over telephone lines. After the folder is compressed, and the accompanying E-mail message composed, it is ready for sending. An alternative way to share E-mail visual information is to create model images with a digital camera.
Time saved is probably the best reason to make it part of the design process.
The kind and make of a digital camera is crucial, however, to its usefulness. Low-end cameras do not produce acceptable images. Having experimented with several available, the only one I recommend is the Kodak DC 50 shown in figure 4. It is, in my estimation, superior to any middle-range camera now available. Even better cameras exist, but the cost rapidly escalates by several thousands of dollars after the Kodak DC50.
