The cheesypic software transforms your rasberry-pi in a full fledged photobooth. The software will work with DSLR cameras and dye-sub photo printers to deliver a high quality photobooth experience.

• Live view
• Custom photo strip designs
• Local storage of captured photos
• Custom themes
• Samba file server

The cameras is interfaced using libgphoto2. In theory the software will support any camera that libgphoto2 support.

Supported Cameras

The printer is interfaced using guttenprint and Solomon Peachy's selphy_print sofware.

Supported dye-sub printers

Note: Some printers may require additional image processing library.

The photobooth uses the 'c' key as a trigger to start the photobooth. A device-tree overlay can be added to configure gpio_1 as a keypad 'c' button.

Compile and install the photobooth_button.dts on the pi using:

sudo dtc -I dts -O dtb -o /boot/overlays/photobooth_button.dtbo misc/photobooth_button.dts

Connect a normaly open button between GPIO_1 and ground.

gvfs-gphoto automatically mounts cameras as a storage device on boot, this prevents cheesypic from using them. To disable gvfs run:

sudo systemctl mask gvfs-daemon systemctl --user mask gvfs-daemon

Finally add the following line to /boot/config.txt:

dtoverlay=photobooth_button

add the user to the lp group

sudo adduser $USER lp

Add your printer to cups using the cups webpage or lpadmin command.

Set the default printer:

lpoptions -d printer-name

Verify the default printer:

lpstat -d

The configuration described in this topic allow you to automatically start the cheesypic software on boot without a desktop environement.
