Everyone is a food photographer these days. So where does that leave Martin Parr, who has been snapping food portraits for 25 years? His new book, Real Food, features more than 200 plates of everyday meals and snacks from 36 countries.He is known for capturing ordinary people at work and play, many of them on holiday at the seaside."You can tell a lot about society, who we are and what we like doing, by looking at the food we eat," he said."As a subject matter, it's quite revealing. It's like a new social landscape so it's been good to explore food all around the world."I am showing food as it really is because we are surrounded by images in magazines in which you see food looking glorious and beautiful, and we know that most people don't surround themselves with food like that. "His daughter is the chef Ellen Parr, who says he works quickly, taking just a few minutes to capture an image with a macro lens and a ring flash.For his first food book, British Food, published in 1995, he used a Nikon and shot on film.He has since moved on to a digital Canon."Food photography [has become] ubiquitous since I started it," he said."I was doing this in the days of film, when it was much more difficult to photograph your food close up, whereas now you just whip your iPhone out and you can photograph everything.''Parr's work sometimes attracts controversy, with critics accusing him of snobbishness for his pictures of ordinary people at play."I'm always amazed about how controversial my images are," he said. "I don't know how or why this happens."I am recording what's there. Of course, what you are looking for are the ambiguities and contradictions of modern life."I'm a food snob so I like good food, but I also like junk food. I even have a Big Mac from time to time. Don't you?"Are you a food snob as well then? Then you are partly to blame for this food culture that we've got, which I'm trying to puncture." ..
