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.
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.
