Photography is my way of celebrating the beauty of the natural world. I am a scientist by vocation and by profession, and I approach photography as a science. I want my photos to be as beautiful as possible, but also as faithful to the subject as possible, as we humans cannot improve on what has taken nature four and a half billion years to accomplish. We can only try to show in our photos what our minds and our hearts can see, but our cameras can't. Photography is simply a tool that allows us to accomplish this. When you look at my photographs I want you to see only the beauty of the world and to forget about the photo and about the photographer. These pages are my vision of Earth. Please join me in celebrating our world.
