Knowing how to use your camera is essential to success as a travel photographer because more often than not, it’s those spur of the moment shots that generate the goods. If you can quickly adapt to the surroundings and know what settings to change in a split-second in order to capture a moment, you’re in with a pretty good shot of becoming a professional photographer.
As with all types of photography, smart business sense is key. There are many ways to make a living with travel photography, and much of it extends well beyond your photo gear into social media marketing, content development, negotiation and sales. But the first step is to get out into the world and shoot. Start with anyplace you've been dreaming of traveling, and go! Plan ahead, do some research, and don't shoot like a tourist. Can't afford to travel? Search for opportunities in your nearest city to begin building your portfolio.
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.
