The first thing you have to do is get them onto your computer. There are
three basic approaches: use a scanner to convert printed photographs, use a
video digitizer to pull images off of a video tape, or use a digital camera
to take pictures that can be transferred directly.
There are a great many different scanners, with different resolutions and
capabilities. http://www.zdnet.com/special/filters/sc/scanner/ is a
fair place to start. (If the link doesn't work, go to zdnet.com and
look for reviews of scanners.)
Video digitizers are mentioned in section (3-16). If you're scanning off
of VHS video tape, you are going to get disappointing results.
Digital cameras will generally give you the best results. A mid-range
digital camera will give you pictures that look as good (when printed on a
photo-quality printer, which are inexpensive now) as a 35mm point-and-shoot
film camera. A few links:
Once you have the photograph on your hard drive, you may want to touch it
up a bit. You can use software to correct for over- and under-exposed
snapshots, remove "red eye", and crop off bits that weren't supposed to be
in the frame. Cameras and scanners should come with image manipulation
software that will help you manipulate and manage the images. Adobe's
PhotoShop (http://www.adobe.com/) is the standard high-end solution, and
their PhotoDeluxe Home Edition may appeal to a less demanding crowd.
Once you've got the images in a reasonable state, save them in a widely
accepted format such as JPEG or TIFF, and write them to a CD-ROM like you
would any other files. You may need to use an "Export" function rather
than "Save As...", because consumer photo software authors tend to use
proprietary image formats as the default.
If you want to create a PhotoCD that can be played in a PhotoCD player,
continue on to the next section. If you're interested in arranging the
pictures into an album, see (3-9-2).
