The buildup of thunderheads during Zambia’s rains often last into the late evening and produces sunsets like this one. A surreal touch to what often can be a surreal place. Every evening, while on our game drives, we stopped for refreshments at sunset and often saw spectacular skies such as this one. This image was composed twice, once by nature and then again in the camera’s frame. With the whole sky as a potential palette, I looked for repetitive shapes and colors, and found the billowing back-lighted clouds at right echoing the painterly swirls behind them.
