How do you get work at Travel Channel, National Geographic as a travel photographer? Or as anything?

Photographers for National Geographic are at the top of their field. Don't expect to get an offer right out of photography school. Look for a job that pays the rent first. Having discouraged you, let me say that there is hope. I attended one of their seminars, which was an excellent orientation to the field. Here is the link to the schedule: a href="http://ngtravelerseminars.com/." rel="nofollow"http://ngtravelerseminars.com/./a In the one I attended, there was a section for pitching ideas. If they heard something that sounded interesting then they pursued it. They seek the kind of imagery that tells a story. It's not the stuff you can buy in a postcard store. So travel and bring your camera. Look for the unique, rare, or surprising and which conveys an emotion or evokes one in the viewer. Build up your experience. Hone your skills. Be self-critical. A good photographer can get a winning shot with a 3 megapixel camera, while a hack will still get junk from an $8,000 DSLR.
