This image expresses the passage of time, as the roofs of these old houses and a single puffy cloud flow across the frame. The composition of the picture helps us accomplish this. Composing this image involved two critical decisions – where to stand, and when to release the shutter. I selected my vantage point first, because that determines what is in and what is out of my frame. I chose a camera position that includes four chimneys and one dormer window, carrying the eye from the upper left hand corner across the frame to just below the middle of the right hand edge. I also kept the spacing around the chimneys at the edges of the frame as consistent as possible, creating tension to energize the image. The mid-day sun creates high key lighting contrast along these roofs. I used this contrasting interplay of light and shadow to build a series of four repeating diagonal thrusts between the tiled roofs. The cloud is also an important element of the composition. It explodes across the right hand side of the frame, carrying the eye out of the picture. I had to wait a few minutes for that cloud to get where I wanted it to go, and only then did I squeeze the shutter release.
