Not any particular religion or school of religion, but being an artist, you have to be spiritual, in a way.

Where do you draw the line as a human being? Written record is only, what, a couple thousand years? And this scientific revolution is less than a hundred years. And computers only a few decades! We've changed so much. It's amazing, the speed of changes.

Photography is like a found object. A photographer never makes an actual subject; they just steal the image from the world... Photography is a system of saving memories. It's a time machine, in a way, to preserve the memory, to preserve time.

Humans have changed the landscape so much, but images of the sea could be shared with primordial people. I just project my imagination on to the viewer, even the first human being. I think first and then imagine some scenes. Then I go out and look for them. Or I re-create these images with my camera. I love photography because photography is the most believable medium. Painting can lie, but photography never lies: that is what people used to believe.

My concept was, within the five-minute video, for people to see one million Buddhas. So I made a group of the images and it keeps accelerating to reach this one million point. The movie was invented from the still photos.

I didn't want to be criticized for taking low-quality photographs, so I tried to reach the best, highest quality of photography and then to combine this with a conceptual art practice. But thinking back, that was the wrong decision [laughs]. Developing a low-quality aesthetic is a sign of serious fine art-I still see this.

Art is technique: a means by which to materialize the invisible realm of the mind.
