This video was on Daniel Stoupin’s Photography Blog (he made it), and gives us a nice biology break before today’s final Easter post, in which believers take the opportunity of this holiday to stomp on atheists. In the meantime, look at some wonderful marine animals in slow motion. Stroupin’s site has a nice long explanation of and rationale for his video; I’ve put an excerpt below.
“Slow” marine animals show their secret life under high magnification. Corals and sponges are very mobile creatures, but their motion is only detectable at different time scales compared to ours and requires time lapses to be seen. These animals build coral reefs and play crucial roles in the biosphere, yet we know almost nothing about their daily lives.
. . . 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.
