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.

It would be so easy to lose the plot now. It's not about achieving something for its own sake, and taking pictures for their own sake. But to make conscious decisions and choices, and it includes this constant questioning - Why am I taking pictures? Because really, the world is... it has pictures enough. I mean, there are enough pictures out there.

Books have this function that help me to understand the work I've done, to wrap it up. Once it's done, fortunately, it doesn't mean there's closure. Change in my work happens not in revolutions - it's more evolutionary.

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.

For example, you now look at pictures from 1968, they are hugely misleading in terms of standing in as an absolute image of the time. Because maybe two percent of the people looked the way that we now associate with that time. I was also aware that what I was aiming for is an idealized, utopian version of how people could be together. I found photography to be a very powerful tool because as long as it looks real, it is perceived as real.

Always take yourself seriously... it's not the same as being pompous, or overly self-assured, but it is important to understand that the small little ideas that creep up in your mind, often contain the germ of a much larger project. All great art wasn't born as great art. It first needed to be recognized by the artist him/herself. Through his or her belief in it, it became true.

I see my practice as picture making. Whatever is available, I use.
