National Geographic photographers are pretty much the cream of the crop when it comes to travel and adventure photography. And now you can get their advice for free with this pdf download of the “National Geographic Guide to Photography.”

The 15-page handbook includes beautiful images as well as succinct information on capturing great shots during your next adventure. And once you download the 11MB file you can upload it to the Cloud so you have it available wherever your travels take you.

The folks at National Geographic have forgotten more about photography than I will ever know.
