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.
You cannot always ask permission, of course. If you are shooting a street scene or a wide shot of a market, you can't run up to everyone and ask if it's OK. In general, people do not mind this sort of photography—it's only when they're singled out that they get uncomfortable. But not always. Be sensitive to the scene in your viewfinder. If people are getting nervous, ask permission or move on.
Honestly, I think this is the smallest source of income thus far in 2015. There just isn’t a lot of demand these days. Yes, I’ve had some works published in major media outlets. I had a two page spread from Iceland in The Guardian, for example. But the traditional journalism work isn’t something I chase anymore. It’s too much work. You spend 95% of your time pitching, and 5% of your time in the field. I really only do traditional journalism work these days if a newspaper or magazine approaches me. In 2015, I have made about $150 a month from traditional journalism.
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.
