Travel photography as a genre is one of the most open in terms of the subjects it covers. Many travel photographers specialise in a particular aspect of photography such as travel portraits, landscape or documentary photography as well as shooting all aspects of travel. Much of today's Travel Photography style is derived from early work in Magazines such as National Geographic magazine from photographers such as Steve McCurry. This genre of photography entails shooting a wide variety of subjects under varied available conditions, e.g. low light photography indoors, available ambient light photography for exteriors of buildings and monuments, shooting on the streets where sometimes conditions may be hostile, capturing moments which rarely recur, capturing the magic of light while shooting landscapes, etc.
The image of Sapphire Kiu; a Hong Kong-based model (above), was made in early December 2018 on the famous (or infamous, depending on your point of view) Temple street, and will be part of a forthcoming audio slideshow (aka photo film) titled "The Songstress of Temple Street". It will tell the story of Qin Yi, a famous Shanghai singer in the 1930s, who "returns" to Hong Kong where she started her career. Some of the images were made in Temple's Street Canton Singing House and the Tin Hau Temple.
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?

I have found Alessandro Bergamini's China gallery to hit all the right notes in that regard. Most of his images were made in Guizhou; a province located in the southwestern part of the country, and well known for its traditional rural villages, inhabited by minority groups like the Miao and Dong. Other images in the gallery were made in Guangxi , another autonomous region bordering Vietnam, and home to the famous cormorant fishermen of Guilin. I haven't been but I read that even though the water is too polluted now for fishing to be sustainable, these fishermen are catnip for many photographers, and earn their living in that fashion.
