I am in Patagonia now leading a photography tour to this beautiful region of southern Argentina and Chile. This is the Perito Moreno Glacier, one of only three glaciers in the world that are advancing rather than retreating. This is a 7-frame panorama of a portion of the three mile face of this massive ice field. The overcast lighting conditions were ideal because this is when the intense blue color of the compressed ice shows best. I used a 24-105mm lens to take the individual vertical frames that made up the shot, and my settings were 1/1600, f/4.5, and 800 ISO. I could use a large aperture without concern for depth of field because when the elements in a scene are at 'optical infinity' -- i.e. far enough away that the lens is focused on the infinity mark -- everything will be sharp at any lens aperture.
