This is a place to share greentexts and witness the confounding life of Anon. If you're new to the Greentext community, think of it as a sort of zoo with Anon as the main attraction.

Be warned:

If you find yourself getting angry (or god forbid, agreeing) with something Anon has said, you might be doing it wrong.

Explain, don't just antagonize. I bet you don't understand the basic physics either. I'm open to learn new things. What is the eye's shutter speed? sustain your claim with sources.

I put "shutter speed" in quotes for a reason. To gather the required amount of light, the sensor must be exposed to it for a specific amount of time. When it's dark, the time increases. It doesn't matter if it's a camera or your eye.

That's sensitivity, not shutter speed. Eye's do not require time for exposure, but a quanta or intensity of light. This sensitivity is variable, but not in a time dilated way. Notice that you don't see blurrier in darker conditions, unlike a camera. You do see in duller colors, as a result of higher engagement of rods instead of cones. The first are more sensitive but less dense in the fovea, and not sensitive to color. While a camera remains as colorful but more prone to motion blur. This is because the brain does not take individual frames of time to process a single still and particular image. The brain analyses the signals from the eye continuously, dynamically and in parallel from each individual sensor, cone or rod.

In other words, eye's still don't have, even a figurative, shutter speed. Because eyes don't work exactly like a camera.

You do see blurrier in the dark, it's just your brain filters it out. You can trick it though by looking at a small bright and moving object in the darkness, like a watch. You will notice that the image outside of bright watch moves with a delay and is blurred.

Also camera images are not that colourful in the darkness, unless you're talking about computational photography tricks used in mobile phones. All optical systems follow the exact same laws of physics and they produce the same results. What's different is post processing by a brain or your CPU in Lightroom.

Are we going philosophical now? If your brain filters it out from consciousness, are you really seeing it? If you are aware that the brain filtered it, did it really filtered it?

Anyways. No, the brain is not a computer, stop.
