Vertical frames are a hallmark of your style, Tim. You make good use of verticality here to press the vertical thrusts of the fence together, creating energy that draws the eye up and out into the slash of light on the tree in the background. Horizontal frames are characteristic of my style. I choose to shoot this same fence as a horizontal to emphasize the play of light and shadow moving across the face of the same fence.
