often look pretty dire when viewed later,
you can edit the tones artificially in Photoshop, but the
way colors come through underwater is not uniform (which is why the
aforementioned Photoshop doctoring isn’t accurate), rather, the distance from
the lens and the reflectivity of the captured object determines how its colors
appear,
but all is not lost,
two
researchers at the University of Haifa have developed Sea-Thru, an algorithmic
method for color-correcting underwater images,
the tool allows scientists—and laypeople—to understand and contextualize the “true” colors of aquatic phenomena like fish, coral, and anemones,
Sea-Thru was developed by Derya Akkaynak and Tali Treibitz in
the paper’s abstract, the duo explain that the way sand appears is
differently modulated by the water than, say the scales on a fish passing above
the sand,
Sea-Thru uses an algorithm to accurately and efficiently adjust images taken underwater,
and the results look pretty spectacular,
you can see the algorithm in action in the video above from Scientific American, and read Akkaynak and Treibitz’s full paper here, I wonder how the program will be offered to aquatic photographers?
