Water, particularly the ocean, has always fascinated me because of the extraordinary effects of changing light and movement. Sydney has phenomenally beautiful beaches with clear water (except after heavy rains). The ocean has varied moods, from quiet calm to playful waves to huge storms. The colours are often astonishing, and the light in the water changes with the seasons, so brilliant in the summer sun that it seems lit from within. But the light and colours also change continuously with the constant movement of the waves and angles of the sun.
