In the same way, photography, for me, has fragmented. You do have people doing bodies of work - often with found photographs - that are quite hard to understand unless you got a very sophisticated visual history behind you. But there are different camps.

The world of photography is very self-aware. Everybody is always looking around. So it's quite difficult to stand up with a megaphone and declare, "This is what I think." As a reasonably shy person, I found it difficult to do that.

We create these walls between fact and fiction, but often the difference between the two is as little as that between a real name and a pseudonym. So I'm not sure about those walls - certainly not in the realm of visual arts.

It's quite difficult to write about photography as a photographer. A lot of better photographers than me have declined to do it.

Social media's currency is the single photograph. Whereas, every time I look at a photograph, I look at twenty or thirty photographs. I'm looking for a narrative. And that's a different kind of construct. If you're a poet and you put a line from your poem online, "The trees bending over gracefully," or something, you can get a tick. But that has nothing to do with your longer poem.

Well, people from the "me" generation use photography to show off what they are doing, to show the world themselves and their friends. Those sort of diarized accounts have always been there. But the phenomena of making those diaries public is new, isn't it?

It's certainly important to include text beside documentary photographs. Furthermore, it's important to include text in a way that's useful and accessible.
