A camera can be a useful assistant to a writer. Photographs of people can help when creating characters; scenes can help with backgrounds and so on. They can help recall, so that what may have faded in the mind can be brought back in lively detail. Many years ago I visited Arctic Norway and Spitsbergen. Fortunately I had wonderful weather and my camera worked overtime.
Such photographs as these recalled the scenery and atmosphere of the Arctic when I was using such settings in several of my novels: The Red Shawl, A Distant Harbour, Secrets of the Sea, The Restless Heart, Secrets of a Whitby Girl.
