A rainbow is a beautiful thing to see anywhere. But when you see one coming out of a storm cloud over a curving road with a magnificent range of sun-splashed hills in the background, it can define grandeur. Such is the case here. Fortunately, the sun was not shining where I was standing, which allows me to shoot from the shadows into the sunny background. Another piece of good fortune was the effect of the rain clouds themselves – hints of color are scattered above and below the rainbow, part of the same optical phenomenon. To increase the panoramic sweep of the setting, I used a 24mm wideangle lens, and found a vantage point that drew the curving lines on the highway directly into the curve of the rainbow itself. And finally, I waited for a car to round the corner, adding a touch of scale incongruity to scene and telling us just how big a landscape we are looking at here.
