Slow Life (Corals)

“Slow” marine animals show their secret life under high
magnification.  Corals and sponges build coral reefs and play crucial
roles in the biosphere, yet we know almost nothing about their daily
lives. These animals are actually very mobile creatures. However their
motion is only detectable at different time scales compared to ours and
requires time lapses to be seen.

Make sure you watch the video on a large screen. This clip is
displayed in Full HD, yet the source footage (or the whole clip), is
available in UltraHD 4k resolution for media productions.

The answer to a common question: yes, colors are “real” and not
exaggerated by digital enhancement. We have only applied basic white
balance correction. However, we used specialized lights to mimic the
underwater ambient spectrum. When photographers use white light
(artificial spectrum) on corals, they simply miss the vast majority of
colours. Corals have spectrum-sensitive colouration due to fluorescent
pigments.
