I know this looks like one of those ‘colour selection’ photographs, where you select a single colour and leave the rest black and white. But this is actually how the scene looked as we lit our little trays of marigold blooms and set them on the the great river, the Mother Ganges, in Varanasi, India. It was a ghostly dusk, silent and mysterious. Downstream the lights of the burning ghats flickered. The river of life and death flowed silently.
