Here is a film image from the days of slide film. Sunset on kokerboom trees in southern Namibia. The key to sunset images like this are a good, strong shapes in silhouette. These wondrous “kokerboom” or “quiver” trees (basically an overgrown type of aloe) are hard to beat for having a distinctive shape.
