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)

    They do. The eye doesn’t have “frames per second”, per se, because every neuron acts independently, instead of as a eye-wide “frame”. But the rod cells that your eye switches to for night vision have slower activation time than the cone cells, allowing them more time to capture photons, before telling the brain about what it saw. Just like how your camera switches to longer shutter times for night vision to capture more photons, before sending them to the SD card.

    Rod cells also respond more slowly to light than cones and the stimuli they receive are added over roughly 100 milliseconds. While this makes rods more sensitive to smaller amounts of light, it also means that their ability to sense temporal changes, such as quickly changing images, is less accurate than that of cones.

      Crazy! Thats it! Thanks a lot!

      So its not the brain composing the image differently, but the actual chemical method the cells use to capture light. Will be hard to modify haha
