The number 69 has different layers for me. Yes, it is a funny number, with its own connotations - I like that my photos of doorways can amuse people.
But I also love the way it looks, it has a beautiful harmony, kind of like a yin yang sign, representing duality, ebb and flow, balance, opposition.
I started photographing these doorways in 2014 and still find new number 69s to this day. This is a small selection of my large collection of the number 69 in Berlin.
