EPS files can be used on all computers, but not all postscript files are the same, or readable among software programs. There is, however, computer equipment that is affordable and available to just about anyone. Also, the skills needed to use this equipment are fairly easy to pick up and the results are usually quite good. There are a number of ways to get images transferred into a digitized format. One way is to take a photograph of an image and then use a scanner to transpose it into a digital file.
Scanners are relatively inexpensive and can be purchased at most electronic retail stores.
Once the image is captured, it can be sent to a personal computer where compatible software can be used to resize it, crop the image, alter the colors, etc. Another way to directly capture a digital image is by using a digital camera. Most major camera manufacturers now offer a diverse line of these types of cameras - many at affordable prices. Digital cameras employ the same principles as standard cameras except that instead of using film, they have a light-sensitive array of sensors that interpret light and then store the image on either internal memory or on a storage card or disk. At present, images from these cameras still lag behind the quality of a good film camera, but the gap is rapidly closing.
