We often travel with people we know—taking a family vacation, for example, or bicycling around Tuscany with a group of friends. We quite naturally want to come home with pictures of them as souvenirs of the trip. Be sure to get these, but don't forget that you can also use members of your family and your friends to make your other photographs more effective.
"Back when we started Wanderlust, we would invite photographers in with their portfolios. Nowadays, although we do commission some work, we increasingly use online stock libraries to find images for this website and for our magazines. On the one hand, they libraries have a wide range and make it very easy to search. On the other hand, we can find ourselves wading through pages of very average shots that don't offer anything different or fresh. And, so often we struggle to find what we need due to poor tagging by the photographers."
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.
