When you read a script for the first time, what is the first image you look for?
"I don't think it begins with one image. First, I need to have a discussion with the director. We might spend time talking about inspiration – paintings, references or movies we have seen – and from those conversations we start to build an idea of what the film should be. You don't always need lots of ideas. Sometimes the choice might simply be that the camera will be handheld and stay with the actors. And even after you have planned it, you can arrive on set, see something different and realise there is a better way. You have to leave room for that inspiration."
What makes great cinematography: an image people notice or an image they simply feel?
"For me it is much more about feeling. Cinema has a language that speaks to something instinctive in us. It isn't only intellectual. There are rules in cinema because they correspond to the way an audience sees and understands what is happening. You have to learn those rules first, but then you can break them when you want to create a particular emotion. A good movie should absorb you into its story. If you have to stop and explain everything, something isn't working. The audience should feel the image before they start thinking about how it was made."
After more than 20 years behind a camera, what can still surprise you on set?
"Everything. Every day we discover something new. I tell my camera crew that when the director says 'cut', nobody moves until I say so. Sometimes the actor is still inside the emotion of the scene; the director may be further away, but if I'm operating handheld, I can sometimes be a metre from the actor. I can feel how they are breathing and moving. I want to stay connected until that emotion is finished, because that unexpected moment may be something very special."
What piece of Canon kit can you not live without, and why?
"The Canon EOS C500 Mark II gave me freedom. We were making cinema on a very low budget and sometimes we couldn't properly light the scene. The camera's dynamic range allowed me to capture the difference between the highlights and the shadows, and work much more easily in such difficult conditions."
What else could we discover in your kitbag that helps you elevate your work?
"The rig is very important to me. It's one of the first things I check before a shoot because I'm the one who has to work with it all day. But I joke with my crew that even if you take my lens away, I can still shoot. I'll make a pinhole! A cinematographer has to know how to find solutions with whatever tools are available."
