Fire your exposure as the wave comes towards you, and as the camera is taking the long exposure you’ll then capture the bioluminescence at its best when the wave breaks.
What creates bioluminescence?
Bioluminescence occurs through a chemical reaction that produces light energy within an organism’s body. For a reaction to occur, a species must contain luciferin, a molecule that, when it reacts with oxygen, produces light. … They can even choose the intensity and color of the lights.
Why is red hard photography?
Vibrant red things often seem too vivid in photographs, especially when photographed as close-ups. This trouble has a lot to do with the sensor in digital cameras. … Since the human eye is most sensitive to green, there are twice as many green sensors. There are fewer blue sensors and even fewer reds.

Does bioluminescence produce heat?
Bioluminescence is a type of chemiluminescence, which is simply the term for a chemical reaction where light is produced. (Bioluminescence is chemiluminescence that takes place inside a living organism.) Bioluminescence is a “cold light.” Cold light means less than 20% of the light generates thermal radiation, or heat.
Can you swim in bioluminescent water?

Can bioluminescence make you sick?
The phenomenon, known as China’s “blue tears,” is actually caused by a bloom of tiny, bioluminescent creatures called dinoflagellates. … The blue tears phenomenon can poison sea life, from fish to sea turtles. The bloom can even make humans sick, Hu said.
