Most digital still cameras have USB ports, and can be used with a computer to download images from the camera. However, that is the extent of the common functionality.

Most cameras do not have any type of tethered shooting capabilities, where the computer can change settings and trigger the camera to capture an image. And cameras that have tethered capabilities (such as Canon and Nikon supported models) have very different interfaces.

We try to support as many cameras as we can reasonably do.
