It's often said that technical developments are making this a golden age for photography. Do you think that's true?
"Yes and no. You could argue it's easier to be a photographer now, technically, because no longer do you have to work out exposures and so on – the cameras do it all for you. But what's more difficult is to find a unique story, your unique relationship to the world. That never changes. So although technically it's easier, and there are more platforms for photography than we ever had before, getting good photographs and having a personal vision is never going to be easy. Thank God, in a sense, because that's how you can distinguish the good photographers from the excellent ones."
How important is technical skill for a photographer?
"Well, in order for me to sell a 50x76cm print for a sum like £4,000 (over €4,500), you need to have a good print. Therefore, my prime motivation is to get the technique sorted so that the print looks beautiful when you see it on the wall – it's sharp, the colours are right, the palette is good, it's balanced. Everything about it works. And it looks beautiful enough for someone to want to buy it. So yes, you have to have the technique to back up what you're saying and that's why I take having a good file and a good quality resolution very seriously. It's like a language: the more verbs and nouns you understand, the better your chance of articulating exactly what you want to say."
What post-processing work do you do?
"I've never processed a file in my life. I just know that when I look at the pictures they look right. Louis, who does that work for me, knows my palette inside out. He knows what I like, how I want them printed, so it's very rare that I say, 'I don't think that print's quite right'. If I do, we tweak it."
Do you have any post-processing ground rules?
"Not really, but I don't push the colours, I don't take things out, apart from hotspots from flash, reflections in eyes, things like that. We're not going to start putting together two pictures to make a better one. I believe in the integrity of the image."
