Pilgrims circumambulate via a series of courtyards and corridors the inner walls of the Jokhang temple, Lhasa. The courtyard was dark, light only entering from above, so exposure times for photographs were long. I noticed the same pilgrims came round again and again at 10 minute intervals, so I sat on the ground with my back against a pillar, my camera resting on my knees prefocused to the spot I knew the pilgrims would reappear. When they reached the spot I had only to press the cable release.

This woman was with a party of family members. There was a great sense of purpose and concentration about her, the rest of the family trying to keep up.
