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)

    we technically have a large blind spot right in the middle of the retina, and that’s why we’re more sensitive to movement in our side vision.

    You’re conflating the blind spot and the macula there.

    We do not have a blind spot in the middle of the retina. If that were the case it would be pretty problematic for vision. What we do have is what’s called the Macula, an area of high concentration of cones and low concentration of rods. Cone cells give us highly detailed color vision, while rod cells only give us overall brightness, but are much more sensitive to light. That’s why, as you mention, we’re more sensitive to movement in our peripheral vision, and also why the center of our vision performs way worse in very low light situations. (Ever seen a faint star that seems to vanish when you try to look right at it? That’s why)

    We do actually have a fully blind spot, but that one sits not at the center of the retina, but off to the side. It’s where the optic nerve enters the retina, and it doesn’t have anything to do with better/worse perception of movement, it’s just fully blind and always gets interpolated by the brain, it literally fills it up with what it thinks should be there. If you get a small object right into that spot for one eye and cover the other eye, it will just disappear.
