i have a hypotheses for how the black and white with the purpleish picture works. I think the reason why it looks like it has color, is because as you stare at the picture your cones become 'saturated'; creating a sort of afterimage . after seeing this illusion I opened a image editing program and removed one of the channels from a black and white image("green" in my case) stared at it long, and then it turned the channel on. It looked greenish. It is kinda cool
D-Mic 年 前
The bright colors leave an imprint or afterimage in your eyes that overlays with the black and white image, as long as you don't take your sight off the image. This afterimage overlay gives it the appearance of a real image.

I also love how he doesn't know what it is, and he says," Oh, my wife loves me." BUt sometimes, he gets the bad one and says, "MY wife does not love me anymore!!!" It just makes it all the more worthwhile and entertaining. Love you Ian!!!

I'm pretty sure the Sydney opera House illusion is quite well known. It can be seen when viewing most things through a window. Since your range of vision is getting smaller, the building takes up a larger proportion of it, making it look as though it's getting bigger.

I don't understand how Changi Airport's artwork that is titled kinetic rain (the bronze raindrop thing in the video) is considered an illusion. I've seen it a bunch of times, being a Singaporean and having gone to Changi Airport quite a few times alr.

Not going to lie.. the black and white picture that turned to color, blew my mind.. I did it a few times and could feel the moments where my eyes started to focus! The colors started pulsing before he changed it to black and white! That was simply amazing!

All of the ones that guy did was based on negative feedback! When our brain perceives excessive sensory information (colors, movement inward, etc.), when it is taken away, it will project/create the opposite. Pretty cool!!

(3:16) It's simple. Your brain is seeing the opposite of what it saw before all the color was removed from the image, causing the image to look real. Basically, the purple the trees were is the exact opposite of the natural green you 'hallucinate' after he makes the image black and white.
INGIE32 年 前
4:28 This has nothing to do with hallucinations, it has everything to do with your eye's color receptors essentially becoming "exhausted". This means that if the image switches from inverted colors to grayscale, only the non-exhausted color receptors will pick up color form the white/gray light, meaning you see normal colors.

Hey! Fun fact. Half of these aren't optical illusions. It's the equivalent of looking at the sun and then looking away. You can still see where the sun was in your vision. That's what happens with half of these.

Tek 年 前
7:33 its probably because of the darkness because green is a darker color and the pink is more of a light color so the down circle is dark and the circle up is less darker making your brain think they switched spots just based on the darkenss because your eye catches the darkness of green and then as it turns gray but dark your brain thinks that green is down and pink is up. Its all based on darkness i think.

It’s because the colors have negative values of each other. Same with the buildings and trees.

MrMcYeety 年 前
for the pink and blue dots, when he made them grey he made the bottom one a darker grey than the top one and since we saw that the pink was the lighter colour, our brains put it on the top. (btw I'm just guessing by what I saw)

I GET HOW 4:26 WORKS! it's tiring out your color receptors, he's showing you the negative of the picture, that way when it turns black and white the color receptors that are strained to see that color get a break and it turns color

the ceiling one isn't an optical illusion this sort of thing happens when you stare at a lite, what I'm wondering is how its not changing colors like it usually does for me

This is how the hallucinations work in the Optical Illusions. They have vibrant colours. making blood conecentrate in a certain area making it as if the colours stay. when you blink that is removed bc the blood is moved aside. thats why they go from coloured. tro grey.

Not a green screen. The Sydney Opera House video was accomplished by a combination of walking backwards and zooming in. This is called a dolly zoom which is traditionally accomplished with a dolly pan system
Einferno84 年 前
For the illusion at 3:47 you are not hallucinating but because you are staring at the dot, you brain fills in the colors around it

The one you said that used a greenscreen was like actually real. Because at the condo balcony, everytime i get farther from it, the view gets bigger. When i go nearer from it, it gets smaller.

4:20 It happens because your eyes have been staring at black so much that they don't want to see black anymore and it fills in the color with memory. ( I think)
