If you’ve seen how underwater time-lapse can show the secret life of a coral reef on this site, then you already know that brilliantly fluorescing corals and sponges have fascinating, unseen experiences. But you’ve never seen “slow” marine animals like this: Slow Life by University of Queensland PhD student Daniel Stoupin.
To make this little clip I took 150000 shots. Why so many? Because macro photography involves shallow depth of field. To extend it, I used focus stacking. Each frame of the video is actually a stack that consists of 3-12 shots where in-focus areas are merged. Just the intro and last scene are regular real-time footage. One frame required about 10 minutes of processing time (raw conversion + stacking). Unfortunately, the success rate was very low due to copious technical challenges and I spent almost 9 long months just to learn how to make these kinds of videos and understand how to work with these delicate creatures.
Make sure that you watch this full-screen, HD actual size. The detail is incredible.

On December 24, 1968, the Apollo 8 crew orbited the moon and discovered Earth. Astronauts James Lovell, command module pilot, William Anders, lunar module pilot, and Frank Borman, commander, were the first people to leave our planet to orbit another rocky body in space, and in this NASA video, we can travel with them to witness the moment they captured this iconic photo of home: Earthrise.
The 45th anniversary video uses data from NASA’s Lunar Reconnaissance Orbiter (LRO) spacecraft with audio recordings, data, and photographs from the orbiting lunar excursion module (LEM) to recreate this exhilarating and unanticipated moment of teamwork.
In the archives: more from the Lunar Reconnaissance Orbiter and oodles of amazing videos about Earth.

Watch a butterfly drink turtle tears from a Yellow-spotted Amazon River Turtle (Podocnemis unifilis). Wait, what?
It’s true: butterflies and bees will drink turtle tears as a source of sodium and minerals. In turn, the turtles get their eyes cleaned. The video above was filmed in Peru by Ryan M. Bolton, photographer/videographer and trained conservation biologist. Farther below, there’s a photo in Ecuador’s Yasuní National Park by conservation photographer Pete Oxford. Via LiveScience:
Turtle tears are not the only source of such salts for butterflies; the insects also readily get the salt from animal urine, muddy river banks, puddles, sweaty clothes and sweating people, said Geoff Gallice, a graduate student of entomology at the Florida Museum of Natural History, who has witnessed butterflies flocking to turtle tears in the western Amazon rain forest.
This region is lower in sodium than many places on Earth, because it is more than 1,000 miles (1,600 kilometers) from the Atlantic Ocean, a prime source of salt, and is cut off from windblown mineral particles to the west by the Andes Mountains. Dust and minerals make their way into the Amazon from the east, sometimes all the way from north Africa. But much of this material is removed from the air by rain before it reaches the western Amazon, Torres said.
