Photographs are interpretations of reality; as such, it is entirely subjective. Most photos are taken with an agenda, to sell something or to make a subject look better than it really is. Think of family snapshots - everyone is smiling and happy.

I think the ordinary is a very under-exploited aspect of our lives because it is so familiar.

I avoid Facebook, LinkedIn and Twitter, and if I need to communicate with someone, I email direct.

Choosing sepia is all to do with trying to make the image look romantic and idealistic. It's sort of a soft version of propaganda.

To ask people's permission to take their pictures? Sometimes it feels right to ask, but I will not ask, unless it is essential to do so. If you asked all the time, you would miss everything. With the exception of portraits, it is generally bad news if people are looking at the camera.

I am not as cross about Thatcher now as I was in the 80s. Begrudgingly, I can see that some of her policies helped modernise Britain.

I never think of photographs as being individual. Always as a group.
