Sea-thru Brings Clarity to Underwater Photos

Post by Racer-X » November 13th 2019, 2:37pm

"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, has figured out a way to recover the colorful brilliance of the deep."

"Hi folks, this is Derya (the researcher in the movie above). Just a clarification: the method does NOT require the use of a color chart. That part was not clear in the video. All you need is multiple images of the scene under natural light, no color chart necessary. For those interested in the exact science."

Really only good for wide-angle situations with non-moving subjects. I notice it leaves halo effects/artifacts.

Generally I don't want to do a multi-photo survey of everything I photograph. I just take a light source with me to overcome the problem. Which also deals with the problem of low-light that her approach doesn't.

Seems to work for me :-)
