photo by Ilda Licon, via submission

A very nice photo of the Gold Line crossing the 101 freeway in downtown Los Angeles taken by Ilda, who is an administrative analyst for Metro. The photo neatly follows the “rule of thirds” — meaning no part of the image dominates the middle of the frame.

Or, as Wikipedia puts it:

The rule states that an image should be imagined as divided into nine equal parts by two equally-spaced horizontal lines and two equally-spaced vertical lines, and that important compositional elements should be placed along these lines or their intersections

It works and you can see evidence of that in Ilda’s photo: the train is on the left side, the cars in the bottom third of the frame and the buildings in the background dominate the upper third of the frame. To my eye, it feels like a properly balanced image and it helps that it’s in black-and-white. Many different shades of gray are in the frame.
