Simply destroy all the cameras in the Amazon level. These are also listed in the collectible guide and it can be found here. An odd thing happened to me on this one so I think I'll share just in case someone runs into the same problem. On my first playthrough, I searched everywhere and made the guide while I played. When I finished the level I did not get the achievement and figured I missed one. I finished the rest of the game and went back to try and find the missing camera. The achievement popped when I picked up the first one in my guide again. Something to keep in mind if you have trouble too.
