The incredible life of coral captured on film
April 2014: Coral as you have never seen before. Film maker Daniel Stoupin has produced a stunning film that captures the secret life of corals, sponges and other marine life in minute, microscopic, detail. filmed under high magnification ‘Slow Life’ illustrates their magical colourful world and transforms your perception.
For far from being the motionless creatures perceived by many, the film actually reveals them as live, graceful, blossoming, sea creatures that operate in a very different timescale to our own.
“‘Slow’ marine life is particularly mysterious. As colorful, bizarre-looking, and environmentally important as we know corals and sponges are, their simple day-to-day life is hidden. Time lapse cinematography reveals a whole different world full of hypnotic motion and my idea was to make coral reef life more spectacular and thus closer to our awareness,” says Daniel in the text that accompanies the film. “I had a bigger picture in my mind for my clip. But after many months of processing hundreds of thousands of photos and trying to capture various elements of coral and sponge behaviour I realized that I have to take it one step at a time. For now, the clip just focuses on beauty of microscopic reef ‘landscapes.'”
