The fascinating video “Slow Life” uses time-lapse macro photography to reveal the surprisingly mobility of corals and sponges. The video’s creator, marine biology researcher and photographer Daniel Stoupin, composited multiple photos for each frame to enhance the depth of field, in an arduous process known as focus stacking. According to Stoupin he shot 150,000 photos during the process of creating the video. He provides some scientific background on the corals and sponges pictured in the video on his blog.
