Water, particularly the ocean, has always fascinated me because of the extraordinary effects of changing light and movement. Sydney has phenomenally beautiful beaches with astonishingly clear water. The ocean has varied moods, from playful waves to huge storms and quiet calm. The colours are always 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 every continuously with the constant movement of the water.
