For me, a good portrait shows the fragility and humility of the person, and at the same time a strength, a resting in themselves.

Whatever pictures are put into the world, the balance needs to be readdressed, it needs to be observed. That's why I am also really questioning what a lot of photography has done since I began. I am not saying because of me, but I mean, photographing some friends partying and publishing the pictures meant something else in '92 than it does in 2011. And I find the younger generation is not questioning this at all today.

The true authenticity of photographs for me is that they usually manipulate and lie about what is in front of the camera, but never lie about the intentions behind the camera.

Growing up in the '80s, questions of style and music and youth culture all seemed inherently political - like gay rights issues, dressing up, wearing makeup, arms protests. A lot of attitude and opinions were expressed through clothes, and they all were meaningful. So in that way, I was so excited about the connection between our private lives and politics - who I kiss, how I like to dance.

A photocopier is a camera in its own right. I was fortunate to grow up in the time and culture that I did. I was allowed to develop an awareness that the art that really moves me is actually based on an original image.

The mobility of the eye is such a fundamental treasure that we have, and that coexists with sensation. On the dance floor, you are totally in reality, while also experiencing this dream imagery of changing colors and wet surfaces of skin. Sometimes it's the shadow outline in the strobe light, and in another moment it's the closeup of an armpit that you're looking into. I'm not photographing all the time, but it's something that I actually see all the time, and not just on the dance floor.

This coincided with the fall of the Berlin Wall and Europe coming closer together, and nightlife and techno and ecstasy culture seemed like a very powerful panEuropean movement.
