There are certain natural phenomena that most photographers would love to capture. Aurora, eclipses, meteors, rainbows, eruptions, lightning and tornados all present challenges to the photographer, not least of which is (with the exception of eclipses) having a camera pointed the right way when they happen. Bioluminescent algae is no different in this regard. Like all the most incredible natural spectacles it is hard to predict and tricky to capture.
