High vantage points often reveal leading lines that can draw the viewer’s eye into and through an image. I was shooting from an upper floor of a building overlooking cisterns built in the year 860 to provide Kairouan with water. Ironically, a 21st century woman in traditional Muslim dress carrying a plastic bottle of water proved more visually expressive than the vast cisterns. She was walking towards me along an overgrown sidewalk, following the curving line of a low curb that separated the sidewalk from the street. I created a frame, flanked by a band of greenery on the left and the curving sidewalk on the right. When the water bearer passed below me and entered that frame, I used the curving sidewalk to track her journey by placing her alongside the powerful leading line flowing from the bottom to the top of the image.
