My wife and I visited Victoria Falls in the dry season during a drought. The water flow was very low, exposing many of the cliff faces that are hidden behind water at other times of the year. Later one afternoon I went looking for a view of part of the falls backlit by the setting sun, with rock ridges silhouetted by the back light. I took a series of exposures from this vantage point, but was not satisfied with the results. So I returned the next afternoon to shoot from a slightly different viewpoint with a faster shutter speed to freeze the plunging water and spray backlit by the setting sun. Since most of the scene was monochrome, I converted the original color image to black and white.
