Classroom Geometry, originally uploaded by marc silber.

I took this shot 44 years ago, it was published a few years ago in a photo-essay I did for Gentry Magazine, so I guess you could say it is now my first professional photo.

Henri Cartier-Bresson talked about how photography relies on geometry. I agree. I see in images that I admire a sense of geometry—the placement of lines and objects. Contrasting proper placement can be things out of place or unexpected as in this shot.

So many times we’re limited to holding the camera in the landscape or portrait position, but what happens when you change the horizon as I did above.

Your thoughts?
