Schaffenburg e.V.'s Photobooth Software

OwO What's this?

This is a linux GUI application which captures live preview and exposures from a DSLR Camera and allows printing or social media sharing the photos.

Features

• Uses libgphoto2 to acquire live preview, trigger exposures and download photos via USB-tethering from ~380 supported DSLR models [1]
• Support for dye-sublimation printers through gutenprint
• Placement of individual full-screen overlay image (PNG with alpha transparency)
• GDPR-aware: allows for photos to be automatically kept or deleted or prompted each time
• Photos can be privately uploaded to a linx server with a QR code for the user to download them
• Photos can be published to imgur / facebook (with optional twitter bridge)
• GUI designed for single-touch screens
• GUI is fully customizable, the widgets can be positioned in a template .ui file and styled in a .css file
• Slider for choosing of how many copies to print (thresholds can be set in the config)
• Strings can easily be replaced/translated, with UTF-8 & color emoji support
• All times can be customized (exposure countdown, save/upload/print idle timeouts etc.)
• Optional face detection for automatic placing of mask overlays
• Optional ICC color correction

Building

Initially developed and tested under ARCH Linux [2].

Requires GTK3+ >3.20

To install this under *ubuntuish distros:

sudo add-apt-repository ppa:gnome3-team/gnome3-staging
sudo add-apt-repository ppa:gnome3-team/gnome3
sudo apt-get update

Photobooth uses the meson [3] build system

pip3 install meson

pacman -S ninja or apt-get install ninja-build

To build, please run:

meson build
ninja -C build

Running

build/photobooth

will run the software with the default configuration from default.ini

• the only command line argument is an alternative config file, where you can specify behaviour, graphics, texts etc.
• for troubleshooting, use the GST_DEBUG=*photobooth*:LOG environmental variable
• optionally uses the facedetect element from gst-plugins-bad which depends on OpenCV [4]
• optionally uses my fork of the qroverlay element [5]
