My daughter immigrated to the USA in 2002. We made this image at her celebration dinner on 2014-09-25.
Our brain makes up most of what we see. It needs to change what-it-made-up, when we look at something new, but we rarely notice it doing that. This optical illusion (above) forces us to see that happen, by accelerating the rate of change. How much does our brains make up?
- Each of our eyes have a blind spot in the middle where the optic nerve enters.
- Our nose adds another blind spot.
- Only 2% of our field-of-vision is sharp, even for people with the best eyesight. Our cheapest camera lenses beat that. Why don't we notice this? In part because our eyes are usually moving, and we see a new 2% every time that they move.
- We can only think about a small part of what's in our field of vision at any moment.
Do we have better dynamic-range than our cameras?
- I can take a photo in the dark, and make it look like daytime after processing. My eyes can't do that.
- I can take a photo of the sun, even though my eyes can't look at it. (Don't follow my bad example. It can damage your sensor.)
- Claims about cameras dynamic-range are for one aperture. Our iris changes size; claims about our eyes' dynamic range are for all iris sizes (apertures).
- We lose color information in the dark, cameras don't.
- Our retina is behind an array of blood vessels. These blood vessels impede our vision. (Not all animals have this problem.)
I am always reminded of the above, when I read that cameras will never work as well as the human eye.
"Fast lane from L.A. to Tokyo"? There is more than one meaning to those words, and all of them are wrong.
Joan Baez, "Light years" is a measurement of distance, not time. Please fix your song, and while you are at it, call up Rob Halford, because he sings "Diamonds and Rust" too.
Neal Schon, Downtown is on the Detroit River, and south of that is Windsor Ontario. Instead of "Born and raised in South Detroit", how about, "There's no such place as South Detroit"? How about a map?
Chris Cornell, "The grass is always greener where the dogs are [shedding]" No it's not. Dog poo kills grass.
