I am excited about more than just youth culture, and youth is also stretching a bit longer now. But I have to say resistance and disregard keeps me excited.

I have always made films simultaneously, so they go hand in hand. I think that my books are like films.

I do feel a kinship with anthropology or ethnography, although when you hear those terms you think of something exotic. Generally, photographic anthropology has that taste of the faraway or undiscovered place. But my anthropology has more to do with what's in my reach.

Holland is a fairly small country, and in a weird way, somewhat conservative. That might surprise people because it is a very tolerant place, but it's also a somewhat Calvinist country. There isn't much flexibility in changing people's perspectives.

Dates can be important. It's a nice way to remember when I took the photo without having to rack my brain or look in the archives. It also makes every photo important, because there is the date. I can take a picture of nothing, but at least we know when I took it.
