iPhone photos of Marjah Offensive
When AP photographer David Guttenfelder followed US Marines during the Marjah offensive, he took along his iPhone in addition to his professional equipment. Using a Polaroid app, Guttenfelder documented the offensive with a gadget owned by most professionals. This shouldn't encourage everyone to become a photojournalist, but it shows that commonplace technologies are capable of delivering high-quality results in the right hands.
Denver Post has the photos.
