Trending in Berlin

This casual observer has again noticed a curious social phenomena.. Around Berlin there are these photo booths which many young people seem to be frequenting.   A throwback selfie. 

Yes the little booth where you smile at the mirror image looking back. You can do anything behind the curtain. 

Of course people cram the party in it to preserve the moment. A short time later out spitz a thin strip of photo paper with four images on it.
