what i've heard is that whenever national geographic photgraphers go out on assignment, the take about 10,000 rolls of film (if you're not using digital) and usually those articles in national gepgraphic have about 10 photos...
wtf man^? anyways NG probably doesnt use film, they use memory cards that can go up to 1GB. but they still use SLR cameras, only digital. we saw the video 'National Geographer Photographers' in photo class btw.
