The Photographic Society of America defines a travel photo as an image that expresses the feeling of a time and place, portrays a land, its people, or a culture in its natural state, and has no geographical limitations.
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.
As travel has become more accessible, more and more, the genre is opening up to amateurs and professionals alike.
Traditionally travel photographers earned money through Stock photography, magazine assignments, and commercial projects.
Nowadays, the stock photography market has collapsed and more and more photographers are using more innovative methods of earning a living such as through blogging, public speaking, commercial projects, and teaching.
