What a beautiful hack by nature. I wonder if you could create a lens with a similarly shaped pupil/iris and see the chromatic aberration in a black and white camera correctly focused on the output. Would make for a fun weekend project :)

The black and white film is still only going to record black and white images ... The "may be able to judge color" part of the theory requires "processing". You might however be able to digitize your black and white photo and "colorized" it.

It would be interesting to develop software that can colorize an image based on multiple images with different focus.

Maybe possible to use this technique on space probes to capture true colors in a single channel, saving on data transfer

  This was brilliant to me at first blush. After thinking about it, though, wouldn't the image have to be a higher resolution to compensate for the blurring of the chromatic aberration? When you process out the blur to extract the color information, you'll have less resolution left over. I'm guessing that would offset the gains on using a single channel. Ultimately for "full color", at a specific resolution, you need a specific number of bits of information, regardless if it's encoded in three color channels, or a single channel.

    Yea just throwing it out there. I think you're right it would most likely require more data

      Kudos for the idea ... getting people thinking about the possible engineering applications is awesome!

      It might still be good for other reasons, though. Like if the colour filters used in space probes degrade over time (I don't know, do they?) then it would allow more consistent colour recording. Also it might be usable on very small probes that primarily take black and white images but can capture colour (at expense of resolution) if required.

  Actually, the opposite, this is the same principle as a hyperspectral sensor. These line scan sensors (kind of like the pupil photos in the article) create "data cubes" (i.e. an 2D image with a 3rd spectral dimension for every spatial pixel) which are huge compared to red, green, & blue images. The article actually talks about how computationally intensive it is to handle and how that made squid so smart.
