Huw Alexander Ogilvie was flying over the Pacific Ocean in 2005 when he shot this peculiar photograph of a lone cloud dumping rain onto the world. After uploading it to Flickr, it quickly became his most popular photo and was even featured recently by NASA in a story about rainfall. You can view a larger version here.
Photographer Dallas Nagata White shot this ridiculously awesome photograph while visiting a Kilauea lava flow in Hawaii. She writes,
My husband and I, along with a tour guide and a group of friends, hiked up to what was formerly the Royal Gardens subdivision above Kalapana, Hawaii, where the last standing house was just recently taken over by the active lava flow. While waiting for the rain to pass, we started taking back-lit portraits of each other in front of the lava flow after I set up my camera on the tripod. For the last photo, my husband spontaneously dipped me in a kiss. It was a truly once-in-a-lifetime moment!
