Libgphoto2是实现访问数码相机的核心库，它为Digikam、gphoto2等应用程序提供接口。当前版本的官方支持列表在这里。这份列表比较保守，某些相机其实也能工作。

本文阐述如何配置libgphoto2，以便访问数码相机。某些数码相机可以直接按U盘模式挂载，无需libghoto2。

安装[编辑 | 编辑源代码]

安装软件包 libgphoto2^包。可选的包还有 gphoto2^包，提供了命令行界面。

GPhoto2用法[编辑 | 编辑源代码]

GPhoto2是libgphoto2的命令行版客户端，它可以让用户从终端或者脚本中访问libgphoto2，从而操作数码相机。另外，GPhoto2也为驱动开发者提供了方便的调试功能。

常用操作

gphoto2 --list-ports
gphoto2 --auto-detect
gphoto2 --summary
gphoto2 --list-files
gphoto2 --get-all-files

更高级的文件操作

gphoto2 --shell

使用 gvfs[编辑 | 编辑源代码]

用下面命令检测连接的摄像头和端口:

$ gphoto2 --auto-detect
Model                          Port                                            
----------------------------------------------------------
Canon Digital IXUS 980 IS      usb:006,011

在文件管理器中使用下面地址进行访问: "gphoto2://[usb:006,011]" - 摄像头会被 gvfs 挂载并通过文件管理器进行管理。

权限问题[编辑 | 编辑源代码]

有本地会话的用户会通过 ACLs 获得摄像头权限，有问题请查看 General troubleshooting#Session permissions。
