When we walk with a camera in hand, we tend to focus on what's in front of us, to the sides as we pass by, or up and down for the more observants among us. But rarely do we look back.

No matter which direction we’re walking, the light is always different behind us. Something we might have dismissed at first glance could reveal itself as extraordinary when viewed from the opposite angle.

Looking back isn’t an easy habit to develop, but it's one that will pay off.

You might be wondering if this will make our walks longer. Absolutely. Much longer. But that’s the point.
