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.

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.

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.

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.

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 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 ongoing coexistence which makes life sensational. The eyes have this ability to flip around what they see from one second to another, to see something as an object, and then as a design. That's really liberating, and I try to convey that in my work, that your eyes are free and you are free to use them.
