Travel photography includes a pretty broad range of topics and subjects. I think of it as a way to document the places that you travel to, as well as the journey getting there. It’s less about photographing beautiful landscapes or various wildlife, although you may do that as well, and more about capturing the emotions you feel and the experiences you have while exploring new territory.
Traveling
Travel photography, by definition, requires traveling. Whether by air, sea, land, or some combination, you need to get somewhere different than where you normally are.

Hiking
Big cities can be time consuming to get around, so will likely require a bit of walking to find the best spots for photography.

Photo and Other Gear
Depending on where you are traveling to, and how you will be traveling, you will need to decide what equipment and supplies that you will need to take with you.

Eating
You gotta eat! Let’s do it right. But again, when travelling you food choices may be limited. So take advantage of those that present themselves, like from a local street vendor.

Other Travel Photographers
Today the Internet is chock full of travel photographers and they proliferate the web with their travel blogs and Instagram pages. But some early practitioners of Travel Photography include people like Francis Bedford, George Bridges, Maxime Du Camp, Solomon Nunes Carvalho, Francis Frith and James Ricalton. Search out some of their work to discover where it all came from.
