Removing colour changes what a photograph is about. Shape, texture and contrast become the story. Look for strong light and clear subjects, and try shooting with a monochrome preview to train your eye. Black and white is less a filter and more a way of seeing.
Great landscape photographs rarely happen by chance. Study maps, check the weather and learn when the light is at its best. Pack layers, spare batteries and a headlamp for early starts. Leave room in the schedule for bad weather, which often brings the most dramatic skies. Above all, be patient and enjoy being outdoors.
