The challenge at the anything-but-wit’s end called for high key photography. I remembered that I’d struggled with an image I wanted to capture in China, the one you see above. The brightly lit stone was interesting in itself, as an example of Chinese aesthetics. Notice the subtle breaking of symmetry; asymmetry is highly valued in Chinese art. But above the artist’s vision, nature had imposed its own: the little touches of colour in the random fall of leaves and seeds over the surface of the stone. I struggled, but eventually came away with something not too far from what I’d wanted.
