Flower Stalk, originally uploaded by Kelson.
An unintended, but interesting effect. It was late afternoon, probably close to sunset but hard to tell since it was overcast, and had just started to rain. I saw this spindly tree with a tuft of flowers at the top and tried to take a picture, but it was too dim. So I stepped back, turned on the flash, and zoomed in. It made the flowers a lot brighter, and the sky a lot darker, than they looked in person.
You can actually see some of the raindrops caught in the flash.
