4.4. Specifying the port and camera you use

Abstract

libgphoto2 identifies a camera by two values: the port it is connected to and the name of the camera. How these may be specified is discussed in this chapter.

4.4.1. Port names

Serial ports

are named like serial:/dev/ttyS2 if you want to use the serial device /dev/ttyS2.

USB ports

As USB works with auto detection, you do not have to specify a device file. Therefore you just use the gphoto2 port usb:.

The port used is stored in ~/.gphoto/settings, so you won't have to specify it the second time you run your frontend, if you're still using the same port.

4.4.2. Camera name

The model name of the camera does not have to be specified when using the usb: port. Otherwise you can specify a camera model like Canon PowerShot G2. You will be better off choosing the model from the list of supported models rather than just trying to type your camera model.


alice@host:~$ gphoto2 --camera "Canon PowerShot G2" --list-files
        

The camera used is stored in ~/.gphoto/settings, so you won't have to specify it the second time you run your frontend, if you're still using the same camera.
