8. Optionally make the software run automatically on startup. To do that, you must simply add a corresponding line in the autostart file of LXDE, which can be found at `~/.config/lxsession/LXDE-pi/autostart`. Assuming you cloned the Photobooth repository into `/home/pi/photobooth`, add the following line into the autostart-file:
```
lxterminal -e "/home/pi/photobooth/photobooth.sh set-time"
```
For this to work you must install `gnome-control-center` by running `sudo apt-get install gnome-control-center` (Unfortunately, this brings along a lot of dependencies - however, I haven't found any lightweight alternative that would allow to simply set date and time using the touch screen).
9. Alternatively, you can also add a Desktop shortcut. Create a file `/home/pi/Desktop/Photobooth.desktop` and enter the following:
```
[Desktop Entry]
Encoding=UTF-8
Type=Application
Name=Photobooth
Exec=lxterminal -e /home/pi/photobooth/photobooth.sh set-time
```

The GUI-class is separated from the entire functionality. I'm using Pygame because it's so simple to use. Feel free to replace it by your favorite library.

Instead of gPhoto2 you can also use OpenCV to capture pictures. This is the preferred way if you want to use a webcam and is particularly useful for debugging on a different machine. For that you must install OpenCV and its Python bindings (run `sudo apt-get install python-opencv`) and then change the `CameraModule`: edit `photobooth.py` and replace `Camera_gphoto as CameraModule` by `Camera_cv as CameraModule`.
