Five Muslims pray near Petra’s historic Treasury, carved out of sandstone two thousand years ago. The brilliant red/orange rock incongruously dwarfs the worshippers. They are totally immersed in prayer, and do not notice the scale incongruity that looms overhead. This photograph was very difficult to make – there were so many tourists swarming around the Treasury that I had to wait several minutes for a clear shot of these worshippers. Fortunately, my opportunity eventually came – just seconds before the prayer ended.
