Seeing is a way of knowing, photography a way of thinking. To photograph mindfully is to look and think, to open a door between what can be seen directly and what is hidden and can only be imagined. The Eye Is a Door: Landscape, Photography, and the Art of Discovery is for all who want to use their eye and camera to think and discover: to look deeply at the surface of things and beyond to the stories landscapes tell, the processes that shape human lives and communities, the earth itself, and the universe.
