How long ago was this? Sensor technology has progressed significantly within the last 15 or so years. There’s a docuseries on Netflix that captured night scenes, including algae glow.

2016. I've watched videos in the past that showed bioluminescence blooms. The equipment was highly specialized (low lux, large 2" CCDs). You're not going to find that type of camera fro <$1000 in your typically electronics store.

Thanks! I am somewhat wishful that I’d be able to capture unique lighting phenomena, but appreciate being brought back down to Earth that some things remain ephemeral and unable to be captured.

In the case of deep-sea predators, there appears to be less bigger consumptive biomass than consumable biomass at present. Currently, it is probably more advantageous for some luminous predators there than the risk of being eaten. The optical perception organs are probably reaching an evolutionary dead end down there. Better eyesight isn't an option. But everything is in flux, it just depends on the time frame. Magne…

You might find electrolocation in fish interesting :) https://en.wikipedia.org/wiki/Electroreception

Thanks for the hint.

I see, the midnight zone is much more diverse then I thought.

It's surprising to me how many creatures have eyes, yet how few can create light. Creating light isn't awfully hard biologically - there are lots of reactions that can create (mostly monochromatic) light. Even humans make tiny yet detectable amounts of light as a side effect of some cellular level chemical reactions. It does use quite a lot of energy, but illumination to levels similar to moonlight is still tiny comp…

Regarding humans making light, is this what you're talking about? https://www.livescience.com/7799-strange-humans-glow-visible...

If you got a chance, Mosquito Bay on the island of Vieques, Puerto Rico, is full of bioluminescent microorganisms. There are canoe tours that let you experience it up close.

I hear they don't let you do it anymore, but when I went in 2007 and 2009, they let you swim in there and it was amazing. Every movement of your arm and legs left a glowing trail of light.

(They stopped allowing swimmers because that body of water is a shark nursery, and one took a bite from the leg of an unfortunate swimmer in 2011.)

Not as warm but it is also very visble at times in the straight of juan de fuca and some places in the puget sound of washington state.

Latest and greatest definitely not but if you just want to dabble and have a camera with amazing low light sensitivity get an older model full frame camera. Camera depreciation is super accelerated and older model pro cameras can be had for super cheap. Ax7 is $650 new currently at amazon, 5d mark ii while a decade old are still amazing and can be had for $100+. Cheap prime lenses are amazing and pro cameras are usually only bought by pros that invest a lot of money in their gear and usually take really good care of their equipment, I mean sure its rolling the dice but isn't every purchase?

Regardless, the world of photography really opens up when you have the pro features, its fun and fun to nerd out on and probably most enjoyable like any new activity (for me at least) is witnessing your thinking change once you start carrying a camera which regardless of the activity (photography in this case) is something I always find deeply satisfying… idk I guess i’m still chasing the high from learning something like physics for the first time but I digress.

That southern sea off the coast of java has always been know for the supernatural legends for generations. Curiously, the locals usually warn visitors to not wear green clothing while visiting that sea because that was supposedly the favorite color of the supernatural southern sea rulers. Curiously, the article mentioned the bio-luminescence glow was blueish-green. Maybe these events have been occurring a lot of times in the past and the locals pass them on as supernatural stories.

I guess most living things put more energy into not being seen so they're not eaten
