Keaton Henson – in pictures

Photographer Antonio Olmos says: "I had never heard of Keaton Henson when I got the job to do a portrait of him so I went on YouTube and saw him sing the song You Don't Know How Lucky You Are, which was amazing and haunting" Photograph: Antonio Olmos for the Observer

"Henson has an amazing face, which photographers love, but he is incredibly shy and he never looked into the camera when I took the pictures" Photograph: Antonio Olmos for the Observer

"Henson suggested we go outside to the roof terrance next to his bedroom window. We did some pics in the drizzly rain and I saw his windowsill full of cigarette butts..." Photograph: Antonio Olmos for the Observer

"...and I mean a lot of cigarette butts. It made a nice photo and it suggested what he had told me earlier, which was that he locked himself away in his flat when he wrote songs" Photograph: Antonio Olmos for the Observer

"The whole session was great and I found him extremely gentle, intelligent, and completely befuddled by the whole publicity game that all artists like him must play at times. I am sure he will have a long career in music" Photograph: Antonio Olmos for the Observer
