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.
I was eagerly planning to revisit some of the neighborhoods with lòngtáng on my forthcoming trip to Shanghai and add to my inventory of candid photography, but was disappointed to read that large areas of Laoximen; one of the most well known of these neighborhoods, are being demolished by the city's government in the name of modernizing the area and raising living standards.
Photographers for National Geographic spend a lot of time doing research. This helps us figure out what's there—what the place is about and what subjects we need to cover. Read brochures and travel books. Go to libraries, bookstores, or onto the Web. Talk to friends who have been there. Pick up travel information at the country's embassy. Find whatever you can that is relevant, and devour it.
