When I look at photographs by Ansel Adams, I sometimes find myself wondering if Adams is celebrating the natural beauty of creation or simply the beauty preserved in our great national wilderness parks. Are his photographs about life or about zoning laws? Of course one might accuse me of asking dreary questions - but I don't think so. The act of cropping a photograph, which is a fundamental act of photography, is at heart a moral decision. In our landscapes, have we cropped out the tourists and the garbage in order to suggest 19th century America (which is to say, nostalgia), or have we cropped out what is truly irrelevant to our intentions as an artist? What photographers leave out is just as important as what they leave in.
