Whenever you’re taking pictures of people or animals, it pays to wait for an interesting moment or action. If you’re photographing another person, for example, just a tiny gesture—a smile, a wink, a glance—is often enough to turn a snapshot into a very interesting photo. It's true of other subjects, too. In the case of this mute swan, for instance, I followed her through the lens for a long time one foggy morning, waiting for a little moment to happen; when she finally tucked her bill down to her chest and created that gentle heart shape, I shot. These key moments don’t have to be dramatic, they just have to be interesting enough to catch a viewer’s eye.
