A great photo is one that makes you see something in a way you’ve never seen it before, especially one that makes you pull a brain muscle trying to figure it out. Exhibit A: Roy‘s image of the platform at Takoma Metro station. When I first saw the image in thumbnail format, it looked like a modern sculpture of an eagle, or something related to Batman. When I opened up the full image, it took me a while to comprehend exactly what I was seeing.
