1590s, "act of appointing," from Latin destinationem (nominative destinatio) "purpose, design," from past participle stem of destinare "determine, appoint, choose, make firm or fast," from de- "completely, formally" (see de-) + -stinare, related to stare "to stand," from PIE root *sta- "to stand" (see stet). Modern sense (1787) is from place of destination, where one is "destined" to go.
If you are a top notch, worldwide known photographer, it is very likely that customers from all over the world will want to use your services (for fashion, events, sports, architecture, products etc.). But as we are focusing on travel photography, commercial organizations that deal with traveling and tourism are more likely to hire you. Notable examples are hotels, tour companies, airlines and so on.
When you really love photographing a certain subject, it shows in your work. If you've built a cohesive collection of images around a particular people or place, consider hanging it in a gallery or selling prints or photo books online. Share your work with artist's galleries in and around relevant locales until you find someone who bites. Southwestern USA photographer Brett Edge took it a step further and opened his own gorgeous fine art gallery in Moab, Utah. Photographer Vivienne Gucwa published a coffee table book featuring her New York City photography. Just getting started? Share your work online for exposure, and upload it to print-on-demand websites for effortless print sales.
Stock photography: Shooting for stock photography is a subject for a different article (or five of them) but you can see stock agencies as the middle man between provider (the photographer) and buyer (magazines and websites). In order for news agencies or image bank websites to send you on assignment, you’re required to be a contract photographer. Each organization has its own contract and demands. But some photo agencies will be willing to pay for your independent travel images if they are sellable. Do not expect large amounts. But hey, it’s better than nothing.
These two portraits are of elderly actors; the type that the cinematic world calls' "character actors" (these are generally defined as supporting actors who play unusual, interesting, or eccentric characters). I found these actors to be much more visually interesting than the glamorous divas; not because of their rugged and wrinkled physiognomies but because they had presence...and must've been part of these troupes for as long as they could remember.
