Jorge,
I recently saw a program on the National Geographic channel (or was it PBS) where the commentator talked about the photography at National Geographic and how it changed the perceptions of people who read it since they always showed photographs of people from different cultures in exotic (to them) costumes and not of people going to work in a business suit(quite obviously).

You will be surprised how many times people here have asked me if elephants and snakes are common in India. My response has been - definitely, in zoos.
