vision and light

top 10 total disconnects between light and vision

1. symmetric encoding of more versus less flux. actually, more neural response to darkness than brightness. neural silence is encoded as a neutral gray. so, a domain of natural numbers, i.e. numbers of photons, is mapped to a U-shaped function of neural response. no, not even a U-shaped function. see Whittle.

2. nonsensical encoding of the EM spectrum. the visible spectrum, continuous linear change in photon energy, wrapped around in a circle? red next to blue? clearly no idea.

3. color constancy and the Adelson illusion.

4. mach bands and phosphenes don't count. these are reasonable side-effects of having a system processing things. you can see the corners of the system, or you can bump it around. no harm here.

i am taking suggestions:::
