Libgphoto2 is the core library designed to allow access to digital cameras by external (front-end) programs, such as digiKam and gPhoto2. List of officially supported cameras is available on the official website (though more may work).

This article documents the configuration of `libgphoto2` to access digital cameras. Some digital cameras will mount as normal USB storage devices and may not require the use of libgphoto2.

## Installation

Install the libgphoto2 package, and optionally gphoto2 to have a command line interface.

### Mount

- gphotofs — Fuse module to mount camera as a filesystem.

  http://www.gphoto.org/proj/gphotofs/ || gphotofsAUR

- gvfs-gphoto2 — GPhoto2 backend for GVfs to mount camera as a filesystem from a file manager that supports GVfs such as GNOME Files, Nemo, PCManFM and Thunar. Part of gnome.

- Kamera — KDE integration for gPhoto2 cameras. Provides a configuration tool and a KIO worker to read and write to camera devices. Part of kde-graphics.

## GPhoto2 usage

GPhoto2 is a command line client for libgphoto2. GPhoto2 allows access to the libgphoto2 library from a terminal or from a script shell to perform any camera operation that can be done. This is the main user interface.

GPhoto2 also provides convenient debugging features for camera driver developers.

Quick Commands

- `gphoto2 --list-ports`
- `gphoto2 --auto-detect`
- `gphoto2 --abilities`
- `gphoto2 --summary`
- `gphoto2 --list-files`
- `gphoto2 --get-all-files`
- `gphoto2 --capture-image-and-download`
- `gphoto2 --set-config datetime=now` - sets the camera to the current time

For advanced file manipulation, use

- `gphoto2 --shell`

Tip: With `gphoto2 --capture-movie` it is possible to use supported cameras as a webcam. See v4l2loopback#Using a photo camera as webcam with gPhoto for details.

### Example usage with GVfs

Auto detect the connected camera and list the required port:

    $ gphoto2 --auto-detect

    Model                          Port
    ----------------------------------------------------------
    Canon Digital IXUS 980 IS      usb:006,011

Now open your favorite file manager and enter the address with the found port detail `gphoto2://[usb:006,011]`. File manager functionality#Mounting will use gvfs to get the camera mounted and manageable with the file manager.

## Troubleshooting

### Permission issues

Users with a local session have permissions granted for cameras using ACLs. See General troubleshooting#Session permissions if it does not work.

### Claimed device

Your system might automatically mount the camera as a file system and then some gphoto2 commands output the error message "cannot claim device". In this case unmount the camera using your file browser or run:

    $ gio mount -s gphoto2
