This was an Olympus-sponsored street walk with Rob Pugh. We were taking photographs in the Tate Modern and I saw this security guard. Being bold as I am with strangers in my street photography, I walked up the guy and started chatting to him. I explained my purpose and asked if I might take a photo. I chose a wide-angle lens and shot from below. I deliberately wanted the hands framing the face but I didn’t want them sharp to take attention away from his face.
