This simple shot is all about framing and mood. It’s clearly depicting a walkway on a bridge or overpass. We can see hints of passive fall protection systems in place to protect pedestrians, behind the railings, that ground us back to reality but don’t overwhelm the scene by any stretch. What makes the photograph so effective is the tunnel effect it has produced, and the sapphire sky overhead. It’s almost dream-like, but familiar. We’ve all walked through a walkway like this, and this is every walkway we’ve ever walked. Very nice, and much thanks to photographer Sean McGrath for publishing it under Creative Commons!
