Magnum photographers were meant to go out as a crusade ... to places like famine and war and ... I went out and went round the corner to the local supermarket because this to me is the front line.

I am away so much, so I rarely see live TV, but I use iPlayer to catch programmes.

I always take photographs when I attend a funeral. Most people there know who I am and expect me to be there with my camera.

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.

Tourism is the biggest industry in the world.

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.

The easy bit is picking up a camera and pointing and shooting. But then you have to decide what it is you’re trying to say and express.
