Tom Jenkins, Guardian sports photographer, explains how he took his extraordinary shots of players at Wimbledon. ‘I had seen images taken by some landscape photographers with infrared and had seen how it rendered colours, especially greens, in a unique fashion. Knowing Wimbledon was a sea of different greens, from the grass to the clubhouse covered in ivy, I though it might be interesting to see what might happen. I also wanted to show a place that is so familiar to all of us, in a very different, almost surreal way.’
