Make use of people to give your images life and scale. If the facade of a particular building appeals to you, the picture may be that much better if you show people walking in front of it. They will give it scale and also let viewers know what sorts of people live there, how they dress, and the like. An outdoor café may be more interesting crowded with people than empty.
When you travel, saving money is often the exact same as earning. Quite often, exchanging a couple images with a hotel for a free room or a tour company for a free tour is totally worth it. In fact, when I was in Southern Africa, I did this a lot. Safaris are expensive, so I’d create a couple images for a company to use for their marketing purposes in exchange for a free safari. It really is win-win.
Travel photography is a genre of photography that may involve the documentation of an area's landscape, people, cultures, customs and history. 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.
