One of the simplest imaging tasks is that of recording a still image. There are two classes of programs for doing this: those that download images that have already been captured by portable digital cameras and those that capture an image from a WebCam or video capture card.

Using gPhoto with a Digital Camera gPhoto (http://www.gphoto.org) is the most advanced Linux tool for interfacing to a portable digital camera. This program, which is shown in Figure 13.7, is still in beta test in early 2000, but is nonetheless usable, even with USB-interfaced cameras.

Chapter 13

When you first start gPhoto, it asks for configuration information—namely, you must tell it what model camera you have and what device you're using. The program has no problems with USB devices, but provides no default USB device filename. If you use a USB camera, you must type its device filename by hand.
