    Why do all the pictures you take underwater look blandly blue-green? The answer has to do with how light travels through water. Derya Akkaynak, an oceangoing engineer from the University of Haifa, has figured out a way to recover the colorful brilliance of the deep.

All you need is a kodak CC30r filter and it will take out all the blues and greens out of your pics and videos.no need for a complicated computer program.

Instagram has this "algorithm" built in already since long ago, but they named it "filters" rather than "see through" 😂

Nice. If you can create a training set of a couple thousand images we can train a neural network to do a very passable job on images without the colorchecker in the image.

The most weird thing about this is, that this actually only came up now. In 2019. O.o How the hell didn't adobe invest in this kind of thing. Seems so easy. Of course, considering you know what you are doing. Amazing idea. Hope she will get paid for this enough and not being bought by adobe or others.

What the hell. I can't believe this has many negative comments. She has done an amazing job. She had created this for researchers and scientists who do research on underwater life and not for those losers who can't even grasp the importance of this

I’m confused why a special algorithm would be needed... Id think a normal color chart and custom white balancing would correct for underwater color cast

So, the chart with known color values is put in frame to provide the algorithm with the info needed to "back out" the effects of diffusion. It's (in effect) the same as using a sheet of clean white paper to reset the white balance on a DSLR before a photo shoot... just using more colors to finely tune the adjustment. Bravo! Sometimes the best inventions aren't totally new, just a new take or application of an existing idea!

It is called “white balance”, If you are an underwater photographer you should know this. I don’t see anything new

This honestly just looks like setting the white balance properly. I've got photos from aquariums that look just like the before and after just by doing that.

This is just color correction, that chart is actually a color checker and is used in filmaking, the computer knows the colors of that chart so when you upload the image to the program, it kind of automatically matches the colors of the image to the colors of the chart, thats why the images is corrected that way.

@gracefool The video is not clear in many aspects, which leads to simplistic interpretations. And the actual scientific paper on the method is too complex for most people. I don't understand half of it, but I'm pretty sure it's not even close to anything we do with Photoshop or Lightroom :)

@KK Foto good point, it uses distance too. If she's really just using the color palette for checking, then cool - it doesn't seem clear from the video.

All them silly scientists are no match for you guys. The method uses photogrammetry to implement a pixel by pixel distance dependent correction that includes scattering parameters and color attenuation. The color chart plays no role in the process. It is used only to check the results.

@strider yeah you're right. All she does is place a color reference in the shot.
