My primary interest is photography, particularly of the landscape. My books "Volcano" and "Stones and Marks" are the outcome of many camera explorations of volcanoes (and their surroundings) and ancient monuments. "The Windmill Collection" came about by the discovery of a vast collection of photographs taken by two women early in the 20th century in southern Australia. Recent work is of people and landscape along the coast of Sydney, Australia, resulting in a book of photographs "The Eastern Edge".
