This would be great for nature documentaries because a lot of animals come out at night.
Hikvision also makes them, and they do work well. you get models that have built in storage in the camera, and, while needing a battery and enclosure for outdoor use, they do work well.and start at roughly $50 for the 0.1lux versions.
There is a colour night vision documentary I just can’t remember the name of it but it exists possibly an Attenborough or on Netflix I will google it and update thee
Just like human beings

This camera just stack multiple frames for long exposure. Downside is ghosting for moving objects
Yes and you can stack pixels in a sliding window to get movement and it also helps reduce the noise allowing you to use higher gains. This is not a new technique. Really advanced stuff uses monochrome stacking for higher resolution detail whilst using frame averaging for colour information at a reduced resolution and merges the two.
@@dr_jaymz
I am working on a solution that takes still color data at a 3-5 second rate from a wide-angle camera and a separate monochromatic video feed at 6-12 FPS to achieve the same. Some multi-cam Android phones allow you to fine-tune the shutter speed and other parameters of each camera separately, so this is quite accessible in terms of technology required.
As you've already guessed, the fairly "low quality" input is then fed to a series of algorithms and models that denoise and auto-balance, then increase the framerate and infer colors from the 3-5 second wide-angle color references.
The wide angle also helps immensely with colour accuracy in moving shots as it captures stuff that are off-view for the motion camera.
Quality will be comparable to this in the end product and it will be able run on a mid-range device with up to 24FPS.
@@vladislavdonchev1271 Wathing the video I was wondering if something simmilar to what you described can be done. That sounds amazing. Will it be avaiable to public? If so, can you tell how to find it?
Yeah, very much looks like computational photography.
This is what actionlab should have told us
I thought Tom Scott came back lol
Same here
I think the red shirt is his trademark, or he had signed an exclusivity contract with Target or something like that 😂
I had the excactly same feelingen from the thumbnail ;)
Dude same that red shirt got me
Fr, me too 😭
I, and roughly 1% of males, have protanomalous trichromatic vision. That means my "long wavelength cones" are actually duplicate medium wavelength cones that are shifted longer but not completely to red like normal L-cones. Under moonlight for roughly 1/3 of the lunar month I can see roughly 20% better than normal human vision. That's because for only 1/3 of the lunar month is the moon bright enough to allow my enhanced cone cells to see more under the spectrum of light that moonlight produces (a reflection of sunlight with valleys in 2 specific wavelengths). I have night vision as far as humans are genetically capable.
meanwhile, the rest of us guys are shlubbing around, unable to tell the different between dark blues, dark purples, and blacks. thanks for making us *look* bad! :-D
By chance do you also have light colored (blue/grey/green) eyes? Those that do have slightly better night vision than those that don't, due to a lack of melanin in their eyes absorbing light before reaching the photo receptor cells.
An even higher % of the population suffers night blindness. Best guess estimate is somewhere around 4% or so.
While not confirmed, my assumption has been for a while that I also have what you have as I have often noticed that I have better night vision than others.
@@ThePhysicalReaction Not him but I have ancestry from hose more northern latitudes, lighter eyes, and a similar experience at night. On a typical moonless semi-rural night away from artificial lighting my night vision is about maybe half the intensity of what’s shown in the color “night vision” at the start, with a modest amount of color, but more washed out. An interesting factoid is that most animals seem to not be able to see things that are standing still or have little relative motion. The tapetum and large iris size gives them excellent sensitivity, but they likely suffer from poor visual acuity. It’s resulted in some sphincter-puckering moments such as my dog and a skunk “booping snoots” in the dark when I wasn’t paying attention since they were walking directly towards each other. However if there is relative motion such as a rabbit taking off the dog can easily see it even when it’s completely pitch black to me. But, it does show why deer stand still at night. I can make them out, but the dog can’t, and I suspect it might be similar for wolves,
@@herzogsbuick That's why I have a wife!
If you are trying to look at faint stars it's easier to see them if you look slightly to the side of them because your peripheral vision is more sensitive to light than the center of your vision
Yep. There is a biological advantage of this trait!
@@westonding8953what advantage would that be?
@@matin563noticing predators or target prey through your peripheral sight.
@@westonding8953 Yes, but I mean the advantage of having worse vision at the center than at the peripherals.
What you said is a clear advantage of having good peripheral vision but it doesn't explain its difference with the center.
You can also notice 60Hz flicker much more easily, especially on CRT monitors back in the day when you looked off axis.
So... nothing really. High ISO + bigger sensor + bigger lenses.
It's the camera equivalent to the Owl!
I didn't get what makes the Argus better at this compared to the DSLR that he was holding at 0:20? Typically DSLRs have a large aperture and sensor. Seems likely to me that the footage from the Argus had gone through (software) post-processing where the DSLR footage had not?
@@Spocoyes. Also, settings in his mirrorless camera must have been set to exaggerate the effect in order to make the reolink camera result better. That Sony is quite known to see in the dark...
Yeah thats what I was left with ! I thought 'Hold on how does it work again ?' and then realized its exactly what you describe !!
@@AlessandroTischer if it's a kit lens, it going to be slow, a faster f1.8 lens is going to be bigger and costlier
Apple has a documentary on Apple TV of animals in the wild with special cameras similar to this. It’s looks so wild so nocturnal animals at night in color
Wifi 7 is actually the most recent iteration. Wifi 6e is the one being mostly integrated and used at the moment though because of how new wifi 7 is.

This is definitely one of your best videos, you explained the science so perfectly without overcomplicating it
It's weird how I didn't really understand "f-stop" even though I've seen many videos explaining it in depth and yet, even though I'm horrible at math, seeing the formula solidified my understanding somehow; MAGIC!
f-stop is a water fountain button, took much and its going up your nose. not enough your mouth is on the nozzle...i hope that cleared it up for you.😀
I noticed that, in the graph of retinal cell activation, the curve for rods is a bell curve. Does that mean that even in the dark, some colours of light stand out more than others, even if we can’t tell them apart by ‘colour’?
That IS what the curve tells us, yes.
Yes, green is the first colour you will be able to tell apart from dark, because that green cone is the most sensitive.
Can be seen in underwater filming, there are videos explaining color light saturation
All darkness is not created equally. Moonlight is sunlight reflected with some filtration. Darkness in a house could be lit by random LEDs coming from your electronic devices.
yes that's exactly right!

You are the world's best physics teacher - and salesman! What a great product, and it can only improve!
4:30 Shows partly how this works with a kind of persistence of vision.I have reolink cameras. The model I have shows a very clear 4k image at night even in low light. It seems to use a slight image delay to process each frame and build up light information for each frame by using data from previous frames (he mentioned you cant have longer exposure than the frame rate, well it seems to get round it by a kind of "persistence of vision"). You can see this in the timestamp above. There is a weird delay (similar to motion blur) when his hand, camera and trees move.
This is great for things that are still or slow moving, it shows number plates and people clearly, however when they move the effect is lost somewhat as the frames dont then have enough data in that spot to use. It still works much better than my old security camera.
The crikets when you show what your camera is filming 😂
Pulls out flashlight.
Yah, I get yah.
I just saw the thumbnail with a red shirt - I thaught It was Tom Scott first. We miss you!
A lot of it is just extremely strong temporal noise reduction. Notice the intense smearing in moving objects - you might as well be using a very slow shutter speed
I wonder if this camera can see musou black as our "regular" black
I'm also curious what the pinkest pink looks like under this camera
ok i'm at 1:41 i'll try to guess how it works, since the Infrared is not a very specific frequency but it's itself a spectrum, the camera emits different frequencies of IR light and then when the camera catches the different frequencies reflected off the the subjects in the field of view a computer on the camera associates the different frequencies of IR light to differnet frequencies of visible light
ok, it was much simpler than that.
WOW, Impressive amount of knowledge perfectly presented in about six minutes. Thank you for making that interesting and fun to learn.
Some of my Wyze cameras have color night vision. It’s pretty cool.
This is definitely cool tech, but you completely lost me at "wifi camera". A security system isn't very secure if someone is even remotely able to hack into/connect to it externally, I'd much prefer my home security be completely closed circuit.
It's pretty much impossible to hack into wifi if the system uses a decent long password and isn't running a totally outdated encryption system like WEP.
@@cube2fox nothing's truly "impossible to hack". New exploits are being discovered constantly, sometimes in things that seem to be well tested and robust.
Besides, with something like a WiFi connected security camera, you, as an attacker, might only really want to prevent it from working, not gain access to it. And doing so is fairly trivial, since WiFi isn't exactly hard to jam.
@@cube2fox Wrong. Done it plenty of times. You're referring to the bruteforce method. There are plenty of ways to get closer to ground truth before starting your search.
A long password is useful, but it's still a literally naive approach - that is to say, no matter how many times a client tries, once they get it right, they're in. Even if you implemented fail2ban on a mac address basis, they could (and commonly do) spoof their mac address.
WPA2-Enterprise is pretty much the minimum to achieve nigh-unhackability, and then you need long, memorable, unguessable passwords. At that point, your domain controller can impede intruders on a user account basis. But if you go that route, *no IoT for you*
IoT devices are also always the easiest way to get the wifi password.
@@LokiScarletWasHere Then you have far worse problems if you are using wifi on your phone or your laptop.
@@cube2fox I have wifi, I just don't have IoT because I use big boi authentication.

You gave yourself away.
The cameras they use at work have colored night vision. It looks just as good as daylight
not as good, still suffers from motion ghosting
I assume what really does all the heavy lifting is the software. They are very likely combining frames. If you watch the first clip and look at his arms while they move, they get blurry and noisy. A simple program could raise the exposure value (EV) of each frame and average out the newest ones (combining them). This would make still objects look bright, colorful, decently sharp, and not super noisy, but this method leaves moving objects noisy and blurry like his arms at the beginning. If not, they might be using some sort of "ai night mode" feature that the latest phones have where some sort of ai algorithm mysteriously turns pitch black footage into something usable. They could be using one or both? Perhaps they are one in the same?
I don't know whether cameras use AI (= a machine learning model) for night mode or not, but I'm sure it works similar to "HDR mode" pictures, where the camera takes pictures at different exposure levels an combines them. Of course a handheld smartphone camera moves a little bit in-between, so the combination process is non-trivial. It has to somehow intelligently combine the pictures while avoiding blur. Simply layering them on top of each other won't work. But for a stationary security camera a "dumb" algorithm would work for stationary parts of the video, because the camera itself is perfectly still. Moving objects will get blurry though unless they do something smarter in the software (e.g. lower exposure for changing pixels etc).
As a rule of tumb (only the last four helps with nights vison and how bright your video and images are and get)
sensor size determines fov and the amount of pixels it can have
Pixel size determines the amount of light collected per pixel and how many pixels you will have
Quantum efficiency determines how many of those photons are converted into a electrical signal
Cooling a camera reduces dark current and thus noise but read noise remains the same higher iso also increase noise the best iso universaly is 800iso
Aperature determines how much light you collect per second bigger aperature means more light
Love my Reolink Duo 2's, but the stitching is not seamless at all. In fact, if your camera covers both a near and far distance, like the length of your driveway, you need to choose if stitching will be close or far. You'll end up with double image ghosting where you don't choose it. In the end, for the features and price, Reolink is amazing.
I Have Reolink PTZ Cellular and Solar Cameras At My House Out Of Town!!! Not A Bit Of Electricity On The Property But I Can See 24/7 If Someone Comes On The Property!!!
Excellent Investment!!! Has Stopped Several "Prowlers" So Far!!!
This sounds hella amazing, i thought it was impossible
Interesting as always. I didn’t know about those color night vision cams. I have myself an older Reolink cam which serves me well but at night only in black and white.
This is the way to advertise a product: making a video about a property it has.
I think most other sponsorships bring a negative reputation to the company because RUclipsrs obviously lie, like "I had to use this VPN service to make this video because a webpage was not accessible from the weird country I travelled to".
It's the first time in a while that I've gotten to one of your videos this early!
Of course it is. Color doesn't go away just because the sun goes down. The stars produce mostly white light, all you need is enough sensitivity in a full color sensor and you're good to go. My Chinese cheapie IMX327 starlight cams give me great visibility with very little light in full color for my front and backyard and I dedicated one to a skycam for meteor spotting, sats, misc unidentifiables. They do smear motion a bit but not near as badly as you might think. Under even modest moonlight you'd swear the view was daytime. Just waiting on advances in tech to get yet better results.
Also, as far as "Can't see in color" goes, that's not the sensor, not the camera really. It's a setting you can usually turn off in order to keep color at ALL times, regardless of light level. That's how mine are set up. I use an additional setting that divides the framerate down to get longer exposure times. I keep mine at 1/2 for a max of 15fps in low light, thus double the light gain at night. Front yard one has the IR blocking filter in place for true color at all times, but the backyard and skycam have no IR filter, so I get visible + IR for almost twice the light gain. Thus nearly 4x normal sensitivity. Also I'm using fast lenses to maximize the available light. I do NOT use IR illumination for my security cams because that's for sissies.
checking Reolink now. Thanks mate! Argus 4 maybe my go to?
This is going to help me take way better pictures.
Hikvision has been making them for years, they are called hikvision colorvu.
I deffinetely love your content, and now i love it more, i have some big anxiety due living in a freaking dangerous place (Literally robbery and even murder has been seen in my neighbourhood) So this is something that gives me hope
The greyscale imaging is not a foreign concept to those of us who are old enough to remember watching TV either broadcast or because we only had black and white TV's.
In the old Moody Blues song "Nights in White Satin" near the end he says, with reference to low light perception "red is grey and yellow white". In low light conditions red light is the first to go.
One interesting fact about the moon is that it only reflects around 3%-13% of the sunlight that hits it. Once way back in college I actually held a bit of moon rock in my own hands. It looked just like crushed charcoal.
Every night vision camera or even binocular or monocular always shoots out a beam of light in the infra-red and/or ultraviolet.
Lately I've been working on seeing, with only my own eyes, everything from microwaves to radio waves. Progress isn't coming as quickly as I'd hoped, unfortunately. 😉
I was very disappointed in those auroras. I live in Alaska where we get them all the time, but they're mostly just shades of green until you get into the -20F or lower range. Well, the ENTIRE DURATION of these ones we have total cloud coverage in my area and we never saw any of them.
Yes. Majority of CCTV manufacturers already have this and have had it for a while now……
What I'd really like to have explained: People agree that we can see little to no color in moonlight, yet it varies significantly how much color we are able to see when viewing the same aurora - which most people are unaware of because we just assume it looks the same to those next to us. Personally I cannot see any color in the aurora except when it is really bright, but I know many others can.
Pretty impressive for such a small inexpensive camera. I think it was only about ten years ago when big expensive digital cinema cameras really started surpassing the human eye in low light.
YES. As exemplified by the sony camera, commercially withdrawn within the 90's because it could see through clothing. Saved you a click.
Is that wavelength curve for rod cell responsiveness accurate? If so, it looks like you effectively have four detectable color bands, not just three. So why couldn't your brain use it for additional color information? Or are the rods all just completely maxed out in daylight giving no effective visual information?
The rod and cone signals are not sent to the brain separately, there are cells behind the retina, that mix them into three signals: red+green-blue, red-green and red+green+blue+rods therefore only three degrees of freedom are left for the brain to decode.
I understand why they are doing his virtually and it honestly makes sense. The security and everything they have to do to bring him in would cause too major a disruption. It was hard enough them to do the court case this would have been worse.
For the good of the probabtion system and to keep everything running smoothly for everyone this is the best option. 😊
I think the US had this technique at the mexican border since several years, but they were way more expensive. They also have incredible zoom where you could watch people from 4k in high detail. The only limit is air movement and heat, that would make the image flicker.
And I did hear rumours about thermal imaging where you could literally see a car's engine's parts move, but I'm not sure how this should work.
It's kind of terrifying that nowadays you can hardly hide from any drones with the right set of cameras.
Drone terrorism is just waiting around the corner... fingers crossed for peace.
3:00 The Aroura Australis was also visible. Trust Americans to not be aware of anything outside their own country
Not as visible to the naked eye, all the photography shared in the media was long exposure
Sony cameras have auto slow shutter option - can go slower than frame rate. Also the Sony FX3/A7S3/ZV-E1 sensor can go to iso409,600.... pretty sweet.
Plese make video about vacuum tubes and vacuum tube amplifier
If you know how FETs (field effect transistors) work, you are already most of the way to understanding vacuum tubes. But the electrons move much faster in vacuum tubes because they're in vacuum instead of a material. There is even a hybrid thing called a Vacuum Channel FET, and they are really amazing, but are barely known outside of laboratories. The very first batch of vacfets made by one laboratory ran 400 gigahertz!
Cold hearted orb that rules the night,
Removes the colours from our sight.
Red is grey and yellow white.
But we decide which is right.
And which is an illusion.
Military night vision scope the color is green.Beyond the range of infrared illuminator is dark black,or if there is no white,colored object in the surrounding appear black which able to camouflaged black object. 😊
Military NVIS use photomultipliers. IR illuminators would make you look like a christmas tree to the enemy
NODS like that would be sick. Its only a matter of time
It's possible. The question is: "Is it possible for consumer priced products?" cause the military might spend $150,000 on a color night vision camera but chances are the average Joe won't.
More like the "advertisement action lab".
Yeah... Sucks man
more like the advertisement lab
Thinks to myself: oh this thing looks great, I’ll have to keep that in mind for when I eventually buy a hou…….oh wait.
as the NZ RMA guy for these cameras, this makes me oddly proud
Using software post-processing, even a regular camera should be able to provide colorful night vision while maintaining it's normal frame rate, especially if it is fixed, by adding up pixels which haven't changed (where there is no motion). Moving elements won't be as bright or colorful, but if they stay in the same spot for one or two seconds, that should be enough to obtain the colors.
It looks like the Reolink camera is doing something like that.
I used CHDK with a Canon digital camera and took a 7 minute and 30 second exposure of my room with the lights off and it was like night vision...a bright glow from the windows at night and the LEDs from the gadgets looks like daytime...If you tried it with a film camera you get reciprocity failure and it takes longer than one night to take a picture...
Yes color night vision is possible. I can see colors at night with my eyes.
Try the Hikvision ColorVU cameras. They are colour night cameras just the same or better

When you were talking about ways to get more light in a frame my first thought was just to multiply the amount of cameras
Do they use this technology in (some) telescopes?
No, telescopes just use a massive imager, and then a really big mirror to catch light, plus exposures that can be measured in hours. Hubble, because it is in orbit, can have exposures measured in weeks for certain orientations, where you do not have any sunlight near the end of the telescope, or close the cover during those parts of the orbit.
@@SeanBZA Can you explain....
How can we focus on a certain object that's lightyears away?
What I mean is, with it being so far away, how is a telescope able to focus on like one galaxy (or a couple) without the light from the distant object being washed out by light from much closer objects?!
I've always been confused about that.
@@ericchin739 Black paint in the optics, and a set of gyro units that allow the telescope to be pointed with great accuracy at a particular point, and keep it there. Focus is simple, as the incoming light is pretty much parallel so can be focussed easily enough, as the telescope was calibrated using an infinity source originally, and it has been checked that it is keeping focus during use.
@@ericchin739 A galaxy takes up only a tiny spec of the sky from our (and Hubble's) point of view. So narrowing the image to that spec prevents other light from washing it out. Galaxies are so far away from us that they either look like single stars in our galaxy, or they're not visible at all. In other words a telescope like hubble can focus on a literally black part of the sky and after exposing that section of sky for long enough, objects will become visible.
As for how they focus, the telescope has star trackers and gyroscopes that keep it it pointed at the exact same location in the sky as it orbits the earth.
@@somecsguy9824
"In other words a telescope like hubble can focus on a literally black part of the sky and after exposing that section of sky for long enough, objects will become visible."
Aye, same with a regulare camera. Just increase the exposure for a few seconds, and you will see far more stars than with the naked eye. But don't increase it too much or you will also catch the movement of the stars / movement through the rotation of earth :D
4:45 F-stop seems to have been redefined at some point - I'm old school and would always insist on saying f/4 instead of f4, for example. To my mind it's obvious that f/4 on a 28mm lens has an aperture of 7mm, quarter the focal length not four times it.
It is possible have a Shutter speed longer then the frame rate. You just have to copy the frame, shift it over by a frame and stack them. Works best if you already film with 360 degree Shutter aka a Shutter speed where it is never closed in each frame.
4:47 it's focal ratio, photography terms are weird.
More aperture more light, lower focal ratio with the same aperture is also effectively more light
night time doesnt look black and white to me IDK what youre on about
This is a super well done video! I thought that the sponsorship was well done and engaging. I loved that you were able to tell the story using the sponsorship as a tool in the story! Great job!
the army has had these for the past 5 years, finally we're getting to play with this tech
Try using this in a musou black painted room!
Canon came out with a security type camera with an extremely high ISO years ago. I think they were pitching it to TV studios who did reality shows like Survivor. So they could film in almost pitch blackness abd still have color video. But that came our almost 10 years ago.
Wyze cams have been doing this for over a year
That's what I use.
Can't be compared, the wyze cams have smaller sensors and the feed is heavily compressed
Wyze are great and they can pick off license plate at 30 feet. Best $26 you will ever spend for a 2.5k QHD!
I dont follow or watch Linus (LMG) any more, but 1 thing that I agree with him is these home automation and home security devices are not good for general public.There are many other channels that share the same concern.
The problem with most of these devices is that, the companies (producing these devices) want to save your private data on their cloud. This is bad in many ways, this gives these companies control over your device's and their service and they can extort a monthly subscription fee, when this is just a hardware device that should save your data locally. You should also not need to connect to the internet to be able to see the feed.
Tomorrow they can change their terms of service, or they can be hacked and your personal videos gets leaked to dark web. Its not like this is hypothetical, since these things have happened with Wyze and with Ring cameras.
In Northern Norway you can experiece sunlight at 2am during summertime
I actually tried to figure out what he was going to say, and i came up with something completely different.
What if you made a digital video camera that took both IR video AND low frame rate/high color video at the same time, and then used AI to combine the images?
Get all the motion and detail info from IR, then use a color image taken maybe once a second, or once every 5 seconds, whatever was enough to capture color, and use the color images to colorize the IR video in real time.
Using cameras like in this video you probably could get a fairly sharp almost daylight quality video image at a full frame rate of 24 fps.
Back in MY day(Actually my day was like the mid 90s)with film cameras, film also has a speed called ISO, the higher the ISO the more sensitive to light the film is, so another trick you could use with film cameras besides F. Stop was to fool the camera into thinking it had higher speed film in it to get that shot that might normally be too dark.
You can use aluminium foil tape and a labelmaker to print out the DX codes and tell the camera that you had the wrong speed film in it...works wonders for making positive film...Tell the camera that you have 50 speed when it's actually 400 speed loaded, then develop as dense as you can go without darkening the part of the film where no light reached..
NO, color night vision is only possible with the presence of light. However, they could use digital color through memory, ai, or some type of computational means.
Why are ghost videos/pics never this clear at night? Every ghost hunter need this camera 📸
Reolink also plays nice with Home Assistant and has a simple json api if you want to write your own scripts.
Bro. Flir, lorex, and sionyx, just to name a few, have had color night vision for WELL over a decade.
You have it backwards, shutter speed can be arbitrarily faster than the frame rate. If the frame rate is 24 fps then the shutter can be anything faster than 1/24 s (it must actually be slightly faster because of the time needed to read the sensor or advance the film)
The video quality of the camera in low light is remarkably bad when there's any motion, with lots of pixellation and very low frame rate, but it nonetheless seems like this camera could be an excellent addition used alongside an IR camera, to get that color information that could help identify people or vehicles.
I love this channel ❤❤
Awesome content. Watched many of you videos running experiments with the vacuum chamber. I thought it might be interesting to see an experiment in miniature of a rocket propulsion system (powder sugar and baking soda propellant?) and if it acts any different in a simulated vacuum of space. I know that Newton's 3rd law of thermodynamics explains what will happen but still might be a good video?
Thanks for all the cool content you generate.
Cheers!
Digital amplification will never be as good as analog amplification, it’s like walking around looking through a screen with latency vs walking around with just regular glasses on
So, this is an infomercial. Still cool.
Best sponsored video.
I wanna talk about that fact that criminals have become so emboldened they don’t even care if they are on camera anymore.
Few days ago i read article about "metamaterial" (or whatever it was), that can literally transform frequency of IR to visible range. Passively. Imagine lightweight nightvision glasses that costs 30$
Best sponsored video I've ever watched. You really know how to make mundane things interesting!
The Amazon ratings for the product is trash. Waste of time
i would be so scared that someone steals my security camera
No way!! I never thought it would be possible!! 😱😱😱😱
All this looks like to me is high iso with the longest exposure time it can manage with a stretch in software. Do the same thing with a normal DSLR or mirrorless with the right lens qnd you get similar results.
security cameras still have an edge on the post processing, they can do HDR, WDR, BLC/WLC, temporal NR, etc.
That's a pretty amazing camera! I wonder if it could be used to see better in the ocean where light is poor.
Funny how we film at 24 fps and everything is fine but dropping under 40 fps while gaming is horrendous.
I’m thinking more on the lines of colored night vision for combat..
I like how you see the interesting physics in your everyday life. Nice video.
I thought they did a nature documentary with this
I remember when we were on a plane, people thought they could see aurora. It was rather faint, so it looked grey. To be sure, I took my camera and took a picture of it. If it had been aurora, the image should have shown green, but it was grey. So, it was no aurora, but just a cloud.
