“I only went out for a walk, and finally concluded to stay out till sundown, for going out, I found, was really going in.” John Muir. Sometimes I marvel how the things you need appear at the right time. I was really interested in Ansel Adams (image above), John Muir and other American environmental artists and writers when I was studying zoology. I visited Yosemite too. Now Muir’s words can guide me whilst researching for a film using material from Derriford. The out is Dartmoor, the in Derriford.
