“Photography is a medium of formidable contradictions. It is both ridiculously easy and almost impossibly difficult. It is easy because its technical rudiments can readily be mastered by anyone with a few simple instructions. It is difficult because, while the artist working in any other medium begins with a blank surface and gradually brings his conception into being, the photographer is the only imagemaker who begins with the picture completed. His emotions, his knowledge, and his native talent are brought into focus and fixed beyond recall the moment the shutter of his camera has closed.” Edward Steichen
