Bob Krist is of course an acclaimed photographer, author, educator and writer, who works regularly on assignment for magazines such as National Geographic Traveler, Smithsonian, and Islands. He won the title of "Travel Photographer of the Year" from the Society of American Travel Writers in 1994, 2007, and again this year at the 2008 convention.
Not only does he have an interesting (and highly educational) blog, but Matt Brandon of The Digital Trekker interviewed Bob over the phone, and has this engaging conversation for download on his Depth Of Field post. Two professionals speaking with each other is always a treat...this one in particular.
