A portrait of the botanist Carlos Magdalena photographed at his work place in Kew Gardens. Carlos is a fascinating guy with an encyclopaedic knowledge of plants. He's one of those people where I just wanted to put the camera down and have a pint and a good old chat. Before we photographed him, he had to talk with two journalists. I watched the light get better and better in the greenhouses and then begin to fade. I waited over three hours before I could finally shoot him, at which point the light was completely gone. All I could do was try and create some drama with my own lighting.
