alt Hacker NewsI think it's important to remember that we're not perceiving some fundamental aspect of light. We're perceiving how the photosensitive portions of our retina convert light to stimulus, and how our brains construct a meaningful image from that stimulus in our mind.
Like film photography doesn't happen in the lens or the world. It happens in that photosensitive chemical reaction, and the decision of the photographer.

It reminds me of how vinyl records are fairly lossy, but they provide a superior experience in some cases because those limitations have been accounted for during the mastering process.
It's an entire pipeline from photomultiplier to recording medium to the inverse process and everything is optimized not for any particular mathematical truth but for the subjective experience.
> how our brain construct
is the only part i.e., we perceive what brain predicts no more no less. Optical illusions demonstrate it well.
Sometimes that prediction (our perception) correlates with the light reaching the retina. But it is a mistake to think that we can perceive it directly. For example, we do not see the black hole in our field of vision where there are no receptors (due to our eyes construction).
Another example that makes the point clearer: there are no "wetness" receptors at all but we perceive wetness just fine.
