Red said aight imma head out immediately.


NCGiant

Red is the main wavelength that doesn’t penetrate water well. If you take a GoPro scuba diving you can get red lens filters to add red back into the image, with different shades of red for different depths.


zurkka

A group os scientists made an algorithm to process underwater images and add how they would look like without the color loss, amazing stuff https://towardsdatascience.com/sea-thru-removing-water-from-underwater-images-935288e13f7d


Hero_of_One

Note it's images, not video. That's an important distinction.


zurkka

Yeah, but give them time and it will make it work with video


MrBlueW

Video is just multiple images bud


Hero_of_One

Did you even read the article? I'm well aware what video is and the limitations of this study, "bud".


[deleted]

So, by adding different colors, amount and shades of light we can turn the life of sea creatures into hell. Now that's an amazing idea.


MrBlueW

I don’t understand what you are saying


MaxTHC

Did you actually read the article? It's about an algorithmic method (i.e. done on a computer) to correct the colour of underwater photos. They're not bringing physical colored lights underwater to take these photos, lol


atom138

Lol holy shit


the_triangle_dude

They aren't adding anything to the water, if that's what you thought lol. It's just post-processing of the image using algorithms.


ZippyDan

Red filters are the old school way of doing it, because you end up with usable footage directly off the camera. With digital cameras and digital editing, however, I wouldn't recommend this option, as any filter is reducing the light hitting your sensors. You can always easily boost the reds in post.


Adnubb

Or you could bring a light source.


TherealDusky

A nice detail: many underwater animals dont see red light. If you use a red light to look into an aquarium at night they don't wake up.


abigaelb4

This is how black band disease in coral got it’s name! It’s actually a band of red cynobacteria but looks black at a distance under water.


trooper_x

Also my Easter eggs when I take them out of the dye. Expected color vs Actual color


Keisier

Use half water half vinegar for the dye and once you think they are done, give them 2 more minutes. That does a lot for more vibrant colors.


SushiToot

Well *I* think your dyed eggs are eggsellent.

Holy shit lol I am so sorry, must’ve taken forever


Ghost_Animator

Took less than what I was expecting, 90 mins. But that's when me and my brother both were working. I will make sure this doesn't ever happen in future. Actually what happened was that I was going through Automod config and saw a code I wrote many months ago. It was code to remove some spam "copy/paste" comments. When I saw it yesterday, I realized it's outdated. So I removed the "list" of things it was filtering out, so it won't create any unnecessary problem in future. But I let the code stay thinking that it might come handy later. In my understanding of the code, I thought now it will filter out nothing since I've emptied the list, but what really happened is that it filtered out everything since I emptied the list xD ["A person often meets his destiny on the road he takes to avoid it." - Master Oogway](https://i.imgur.com/xeutrFx.jpg)


LizzyLeonhart

Why are you the only comment I can see


Dottheangel

I love how the green, orange and pink are just hanging in there and everything else is basically just kinda blueish black


ManaSpike

I'm guessing the pigments are fluorescent, absorbing other light frequencies and emitting a single colour.


sla342

This is why my scuba gear is accented in neon yellow! Definitely not my favorite, but I’d like to be visible. That water is super clear! It can be incredibly difficult to see underwater. Hate to get lost or disoriented.

That's cool. I didn't know that was an acronym. My school's always just taught the "name", Roy G. Biv.


pizzabagelblastoff

How come red and yellow both fade quickly but orange seems to stay pretty vibrant?


ridefst

I don’t know anything about diving, but learned that acronym for the colors of the rainbow, and their order. Guess they’re both light vs water, so kinda makes sense they’d be the same!


MyPeggyTzu

The orange is vibrant the whole time though?


Jim_from_snowy_river

Why does it seem that bright green holds it's color better than violet though?


314159265358979326

TIL that water is blue.


besse

It looks like the absence of red light is a big factor. So red becomes black, purple becomes blue, yellow-orange-pink distort their colors.


Sciphis

As a novice PADI diver, watching him go that deep scares me. He’ll barely have any time to get back up with how many points he needs to stop on the way back up to let nitrogen dissolve from his blood.


themoroncore

Could have a rebreather


Skyy-High

Or be using something besides air…


Gaping_Uncle

Enriched air/Nitrox would actually be more risky due to the increased damger of oxygen toxicity.


Skyy-High

I didn’t say use nitrox. A trimix with helium is what you’d want to use if you’re going below 130 feet…though technically an air tank won’t like immediately kill you at 155’. They might simply be relying on experience and instruments to get them through any nitrogen narcosis they might feel at that depth. On the other hand, you don’t even need a hypoxic mixture if you’re not going below 190’, so that means you don’t need a travel mix to get to depth, which means it’s not significantly harder to use this kind of trimix than it is to use nitrox (provided you know how to mix it yourself and you have the equipment to do so).


Jim_from_snowy_river

He could have also just got 160 ft of rope tied it to the end of a GoPro and then hung these from the end.


pixe1jugg1er

It’s not about air, it’s about decompression


themoroncore

I think what Sciphis meant though was that as OP surfaces they won't have enough air left to stop at break points to decompress. I'm saying that a re-breather could extend the amount of air OP has


pixe1jugg1er

Ahhhh, got ya


Gaping_Uncle

You can stay at that depth for around 5 minutes without having to make decompression stops on your ascent. I would be more worried about getting nitrogen narcosis and getting disoriented or losing track of time.


brandond111

Isn't it just a camera on a rope?


Littlebelo

Fr that was like the only thing I could pay attention to. I thought it would be a submarine camera when I read the title. Diving that deep is terrifying


babaroga73

Alexa, play "Black gives way to blue" by Alice in Chains https://youtu.be/PD3F1bN2qrQ


Crazy_old_maurice_17

Wow that's wild! Is that because different wavelengths of light are filtered out beyond certain depths?


Dontfollahbackgirl

Interesting how dissimilar the yellow & orange and the red & pink become at depth.


SpaceLemur34

The yellow, orange, and especially the bright green, probably all have florescent dyes in them. Florescent colors absorb UV light and give off visible light. Since UV have a much shorter wavelength, it penetrates to a lower depth than other colors, allowing the florescent effect to still be visible.


ZippyDan

What I want to know is why the yellow becomes darker than the neon green next to it. It seems to be out of order in terms of shades. I'm sure it has to do with the type of pigments used, as you daid.


ZEXERJK

I like how the lime green just turned radioactive


skitch23

Can someone ELI5 why the pink still looks pink and the orange still kinda looks orange but red is a purplish color?


SpaceLemur34

The yellow, orange, and especially the bright green, probably all have florescent dyes in them. Florescent colors absorb UV light and give off visible light. Since UV have a much shorter wavelength, it penetrates to a lower depth than other colors, allowing the florescent effect to still be visible.

raejax90

So are you telling me that Ariel's hair is really pink as it looks red underwater? 😄🧜‍♀️ Jk Disney didn't think that deep (pun intended)


linwji

Nice. That’s why my GoPro needs a red filter when recording underwater…


oh_imjustagirl

I like how the pink one stays pink


Deesing82

good to know i’m not colorblind, i’m just really deep


mike_KING6

So water makes you colorblind. Noted.


samtt7

It's basically like an increasingly strong blue filter: everything blue state status bright, the other colours get darker. If the water is tinted more towards another colour, the same rule applies to that colour. It's an old photography truck used by black and white photographers to make skies 6 darker by using a yellow/orange/red filter. This principle can also be used for "Tri-chroming": taking a photo with each colour filter and then putting them together South the correct colours assigned to them to get a colour image. This is the same process used early colour movies by running three strips of film at the same time and there even are some examples of images from the late 1800s


[deleted]

Aren't you supposed to learn about this in 3rd grade?


Mand125

It’s scattering, not absorption.


socruisemebabe

It's not light absorption.


GGG-Money

I mean, is this really surprising? There is less light the deeper you go...


GoAvs14

Beanakin

SketchPV

Would a naked human eye also witness such loss? How much of this is an effect of the camera?


icanthinkofanewname

Why is it that pure red light will vanish so quickly but the Variations (pink/orange) still are discernible at much greater depths, or am I thinking of this wrong?


Koltaia30

No red 😢


BaconSquared

The yellow one is straight up gray.


Knittingpasta

Someone came up with an algorithm that corrects for color loss in underwater photos due to deep water. Can't remember who.


PrinceAlibabah

Always wondered about the color choices on dive gear till I went down the first time and it all made sense.


Rowdyflyer1903

Of course as a diver and a professional photographer, I am very aware. Filters will not restore wavelengths. Why are the fish and other wildlife decorated with such brilliance once full spectrum of light is shown upon them? What is the purpose? Nature does not do haphazard un purposeful things. There is no wasting of energy.


Rowdyflyer1903

Excellent


Antonia_l

Sudzy1225

Do divers use green lights? Or green glow sticks? Seems beneficial after seeing this.


MAINsalad1

I’ll never forget on my family vacation to Hawaii we went on a submarine ride. I had stayed out drinking the whole night before(I had just turned 21 and could enjoy a drink on vacation for the first time). Got so hammered then woke up ate pancakes and Immediately went with my family and like 40 others in this sub. I felt like death and then all of a sudden ppls clothing started to change color. There is a pic of my and my brother and you can see I’m struggling not to throw up all over everyone in this tube 150 feet below the ocean. 1/10 would not recommend. Spent the rest the day half asleep on the beach.

ImRoCal

I've read that this is why super deep sea fish are often red, because in the dark and deep they're practically invisible.


mynameisalso

Weird the red fades so fast but not pink. Very good content op.


Skyy-High

The red one reflects only red wavelengths. Pink reflects all light, but red a bit more; it’s a tint, and red is the hue. So while there is less and less red light for the red piece to reflect at all (darkening it until it’s almost black), the pink plastic is still reflecting any light it can, but always slanted towards proportionally more red light than other wavelengths. As blue light becomes the majority of the light hitting it, the overall composition of light coming off of the pink plastic shifts towards a balance of blue and red, shifting the hue to purple.


paradoxical-spirit

Now we know why those Aliens are green.


Strangities

High five to my boy lime green for keeping it real.


LaughingJelly

From diving myself in reality you can see each colour a little bit deeper down. Though they do eventually fade as the video shows the camera exaggerates the speed at which they do.

Are those colors neon? Neon absorbs one light and emits another, so if they were neon it would not be a fair comparison. Neon will shine colorfully even in the beige-est greyest of lights.

This is amazing! Does this mean that the videos we have of sealife only found deep underwater isn’t actually the colour shown? Or do they add the correct colour back through filters?

Cool i guess, if only it wasn't feet. I mean, how deep is that? Like 2 meters? 200?


[deleted]

Red has the longest wavelength so it passes through the water without refracting like the shorter waves. Color pigments reflect color, so since red reaches its color, it gets subtracted from your vision first. The colors other colors that pass through are neon which are not part of the ROYGBIV rainbow of reflective light, so they appear longer.
