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.
When you arrive at your destination, be open and try to take note of the first impressions—write them down if you have to. (A notebook is an essential accessory for a travel photographer.) When you see a place for the first time from the plane window, or when you drive around a bend and there it is, or as the ship nears some distant island—how do you feel? Where do your eyes go first? What do you notice about the place right away? A smell? The heat or cold? Blistering sunlight? Mysterious fog? A particular building or vista? The way people move? Their dress? Whatever it is, remember it. First impressions are invaluable sparks to creative interpretation, and by definition are not repeatable. You've seen the place in pictures, you've read about it. Now you're there, and all your senses can partake.
