Changing the FPS would not change your exposure. Changing the shutter angle/speed would. So does changing the aperture. We don’t have shutter speed in our eyes, but we do have an iris! Your eyes actually change your iris aperture naturally when in the dark.
You can even trick your body to change the iris on only one eye. Cover one eye for a few minutes (at least 15-20min) in a brightly lit environment then move to a rack room (not pitch black but very minimal light) and open your covered eye. Your covered eye’s iris is already wide open and you can see well from it. The other one needs time to adjust.
This is why pirates were wearing eye patches, to be able to enter the hull of the ship and see immediately without lighting up a candle. Fire is not a good idea inside a wooden ship filled with black powder.
This is one theory for why pirates wore eyepatches. We haven't found any historical evidence to confirm it. Meanwhile, we have at least a few documented cases of pirates wearing eyepatches for protecting a damaged eye.
I discounted this theory the first time I heard it because it's too cool.
And what's the parrot for?
Pirates are often associated with tropical waters where parrots live. They probably took them as exotic pets, just like people today.
And: Rule of Cool.
Yeah, I know. I was jk. You're right tho. They're cool af.
Snack.
His snack or mine?
Yes.
Nice. After 6 years of wondering what those eyepatches pirates wear for in movies were for, I randomly learn it from a random Lemmy post.
Eye patches can also be used for eye injuries, in which case, removing your eye patch in the dark will not help you see better…
I meant the ones that pirates in movies wear.
Retina has mechanisms to flip different switches and go into high sensitivity mode. Changing the ISO, if you will. The pupils change consensually under normal physiological circumstances. Even with only one eye closed. If they don't, you might want to go see a doctor!
Well I certainly wouldn't want to change my pupils without their consent, that's for sure!
True! And our nightstand vision receptors don’t see colors as well. That’s why things look black and white at night. That’s also why you need to desaturate your image if you’re filming something that is supposed to take place T night because the camera keeps full saturation even in low light.
