These raindrops were on the back window of a friend’s car, after the rain (appropriately). This was as close as I could get with my 50mm lens; I put the focus right in the center, so it fades out toward the edges. I liking how the reflections of light and clouds in the background turned out. You can see an outline of each drop on the underside of the window below, which is also interesting.
The blue colors were largely fabricated. I darkened the photo and added contrast for effect.
