Keen Vincentia photographer Corinne Le Gall last week spent three cold nights capturing Jervis Bay in all its glory, with bioluminescence on display.
The blue tide, as it is known, is the production and emission of light by a living organism.
It occurs widely in marine vertebrates and invertebrates, as well as in some fungi, microorganisms, including some bioluminescent bacteria and terrestrial invertebrates such as fireflies.
It provided a superb show for Mrs Le Gall last Tuesday, Wednesday and Thursday nights.
"2013 was the last time the bioluminescence gave us a great show," she said.
"The colour of the water on Wednesday night was the beautiful turquoise that I captured the last time, although later on, light punching through the denser cloud cover actually rendered the bio a bluer colour.
"This shot is straight out of the camera, without any alteration - not even straightening.
"I was chuffed to notice the nice starburst effect my camera captured on the house on the right."
She said while bioluminescence is not a rare occurrence, a lot of factors need to be in play at the same time like the tide, no moon, no light to make it happen.
"And you have to be willing to put in the time," she said.
"We were photographing around midnight and into the early morning.
"Luckily, I live five minutes away from where this photo was taken and wasn't afraid to get up at all hours to get the shot I wanted.
"You need to get out of your comfort zone wherever and whenever these beautiful subjects happen and have the determination to grab the moment."
