Just a quick demo of our DIY Photo Booth. The software used on the box is open source and can be found on Github:

As camera we currently use a Canon EOS 5D Mark III. The printer shown in the video is a Canon Selphy CP1300 printer. The box contains a raspberry pi, our custom designed controller board as well as some electronics to trigger the photo.
