The July 1906 issue of National Geographic featured its first ever wildlife photographs. Editor Gil Grosvenor printed 74 photos snapped by U.S. Representative and early conservationist George Shiras, beginning a long tradition of featuring wildlife photos in the magazine.
These photos were all taken on a 4x5, using glass plate negatives, which makes them even more amazing. Do you know how hard it is to take a portrait with a 4x5??? Its really involved and this guy was making tip wire deer photos at the turn of the century.
Check out the national Geo website photo collection, it is truly amazing.
