Whether you're licensing photos through an agency or you're working with local businesses, destination photos sell. If you're just starting out, consider uploading your best work to sites like 500px, where you can offer your images for license quite easily. If you already have a strong portfolio of work, consider applying to Stocksy, the most reputable agency in the stock photo business. Interested in reportage? You can sign up for a Demotix account to get started in travel photojournalism.
In many tourist destinations, people may ask for money if you want to photograph them. Many of these places are desperately poor, and people have few ways of getting hold of cash. The money they ask for is usually not very much to us, but may represent quite a lot to them. How you deal with these situations is up to you, but remember that every time you buy a postcard, you are happy to spend the money for a picture somebody else took. Why not spend a little on your own?
The Yuen Po street Bird Garden in Hong Kong was built in the late 1990's after the former "Bird Street" at Hong Lok Street was demolished. It was built to preserve the spirit and popularity of the bird stalls that once were in Mongkok. The Chinese have traditionally liked to keep birds as pets, and this tradition is maintained in this small garden. Men (I've not seen a woman there except those selling birds, birdseed and live crickets) walk around; whistling at the caged birds, from delicate canaries to colorful parrots, admiring their plumage and a few walking their pets in cages.
This was a really informative article Hillary :) Just wish I found it sooner because just a week ago I went to the Grand Canyon to snap some photos. I didn't have this article to help, but I found a similarly useful article that provided some kind of checklist of things to do before traveling. If anyone's interested, here's what helped me out before I went to the canyon: http://www.adoramapix.com/blog/2016/10/16/photography-101-packing/#.WFH9...
