The Behind-The-Scenes Sarah Dunn Photos We Can't Stop Looking At...

British photographer Sarah Dunn is renowned for her glossy portraits of the world's biggest stars - from Keira Knightley to Jack Nicholson.

But before she gets down to business, she likes to have some behind-the-scenes fun with a Widelux panoramic camera. Now showing in a new exhibition, called Wide-Eyed, we asked her to pick her favourite shots...

1. Ewan McGregor, Los Angeles, 2002

Ewan and I were having dinner in LA, and I mentioned I'd just bought a camera, my first Widelux. So he invited me on to his film set the next day to try it out - he was shooting Down with Love with Renée Zellweger. This was my first, and still my favourite, shot on the Widelux.

2. Liv Tyler, New York City, 2003

This was shot for a Lord of the Rings portfolio. Liv was the last person we photographed. It was a project that snowballed, and she was so happy to be there and take part.

3. Michael Fassbender, London, 2012

We were backstage at an awards show, it had been ten years since I first photographed Michael, and we were reminiscing about our first shoot in my tiny north London flat.

4. Rosamund Pike, London, 2013

We were in a spooky house in east London. Rosamund sat down for a drink of water and suddenly it was so chic and glamorous. The Widelux is an amazing tool for recording the chaos around the calm.

5. Jennifer Hudson, London, 2011

It was an unusually hot spring day, so Jennifer and I ran up to the roof. I love that this camera records everything around the subject - it's a nice memento of how to improvise.

6. Dominic Cooper, London, 2011

I shot this during Movie-Con, a fan convention at the London O2. I was literally set up in a broom cupboard; the camera makes the room look enormous. Dominic is always fun and easy to work with.

7. Paloma Faith, London, 2013

I love working with Paloma - she knows exactly where her light is and is very professional; it was nice to catch her in a down moment.

8. Jodie Foster, Los Angeles, 2009

I was working on an icons portfolio for movie magazine Empire, edited by Steven Spielberg, and Jodie was one of the icons. She was very shy and nervous; the camera was an excellent ice-breaker.

9. Tom Hanks, Los Angeles, 2009

Tom was part of the same icons portfolio as Jodie; he's holding court in this photograph and you can see my reflection in the mirror. He has lots of stories and was a real movie star.

10. Sienna Guillory, Los Angeles, 2012

Sienna had kindly agreed to help me out on a moving image shoot. We drove up to Mulholland Drive - the light and landscape were amazing. It would have been an insult not to get the Widelux out.

Wide-Eyed is at The Strand Gallery, 32 John Adam Street, London, WC2N from 2 -6 September 2014. Visit www.sarahdunn.com for more information.
