My phone is normally worse for color gradients and contrasts than my eyes. Also, normally it has worse nightvision.

But when decreasing the shutter speed, for example in OpenCamera, I get crazy night pics.

I see that when its dark my FPS goes down, I see less frames automatically and totally cant control that.

Could this mechanism be altered, to have even less FPS but more photons in the soup to get brighter sight?

Yes, trying to hack my eyes here. “Getting used to darkness” is normally the pupils getting wider, there are quite some interesting plants to do that but I havent heard of anything altering the brains image processing.

Edit

I learned:

  • in Nightsight we use the rod cells, which take longer to send a signal. That way they capture more photons, but the “FPS” is lower
  • you can trick your iris naturally to stay open, like the Pirates did (some plants like nightshades also do this, applied locally)

    Feline vision has drawbacks, and some adaptations we don’t.

    For one, cats have reflective eyes, rather than absorb light, that misses any cones/rods, cats reflect it back out, passing the light that comes into their eyes through their retinas twice. This improves how much of the light actually hits the light sensitive cones and rods in their eyes.

    Second, cats have slitted pupils, this means they have a MASSIVELY larger range of light they can adjust to let into their eyes. Slitted pupils are able to close much tighter, and open much wider, than circular ones. If you’ve ever seen a cats eye in the dark, you know their pupils get HUGE. Several times that of humans.

    As for a drawback, cat eyes suck at focusing. All cats are far-sighted. At less than about 20 cm, cats cannot see. All they get is a blurry mess. Ever wondered why your cat seems completely clueless when you set down a treat right in front of it? That’s why.

    This is why cats have whiskers. Close up, they go 100% by smell, hearing and feel!
