Dew Droplet Refraction
ISO100, f/8, 1/60, no flash used
Before you ask, this was post-processed for color, sharpness, etc, just like every other photo on flickr, but the refraction in the dew drop was not altered, it's completely natural. That's a refraction of the world behind it, upside down and backwards, not a reflection coming from the foreground, which is why you don't see me in it.
What you do see is my neighbor's house upside down, with the morning sun rising and beaming through the droplet.
