It is cold, wet , misty, turning to sleet. The East wind is coming in from the North Sea. A good day to leave your camera – and yourself – at home. But that is life – the inhabitants of the lovely old city of Edinburgh have to put up with it anyway. So B&W film comes into its own. The “soot and whitewash” effect reflects the conditions. Granite buildings may look their best – but don’t look themselves – in bright sunshine. Stone-flagged pavements become mirrors in rain.
