Yesterday I was out and about in the centre of Melbourne (where I live) doing some people watching (with a coffee in hand) and I found myself particularly watching the many people with digital cameras (mainly tourists) taking pictures of each other. One of the things that I noticed most about them was the distance that they put between themselves and the people they were taking the shots of - it was almost always 5 meters or more - sometimes they even crossed streets to take photos!
While I understand that they wanted to put some of Melbourne's great buildings in the background of their shots I found myself wondering whether the results would be cluttered images with subjects that you could barely make out the features of.
Getting in close to your subject is not something you'll want to do with every shot you take, but it is a very worthwhile technique to learn to use.
