I'm particularly interested in how you can't rely on your own perception.

Photography can be a deceitful, superficial medium that leads us into believing something even though we know it's not necessarily true. It lulls us into a false sense of complacency.

Celebrities do look different in real life from our images of them - there is a big gap. And that is what my work is about: the gap between the image and the celebrity themselves.

I am fascinated by the Royal Family because they are shrouded in mystique, and the Queen, and to a certain extent William, represent fabulous blank canvases. I find the Prince of Wales less fascinating because he spills the beans and we know too much about him.

You can watch a little bit of war from your nice living room - 30 seconds of what's going on in Syria - and when you've had enough, switch over to some celebrity programme. We live our life through screens and images in this way, and we don't know what is real or fake anymore. It doesn't matter.

A lot of people who look at my photographs think it is an easy joke, but it does take a bit of thinking about.

You can't rely on your own perception when it comes to anything. You can always be proved wrong.

I'm not satirical in a traditional way. What I do is more about creating caricatures and cartoons. I am commentating on the nature of how we live through photography, and how you can twist an angle to create a different perception of a person.
