Camera Obscura I Science in the City I Exploratorium

On the cliffs above San Francisco's Ocean Beach perches a landmark observatory-a giant camera obscura. Step inside with Robert Tacchetto and see how this centuries-old technology creates enchanting images of the outside world.

Amazing, and such a beautiful and captivating scene to capture.

You couldn’t pay me to leave if I lived near this masterpiece of an attraction.

[@onedim23]

This was beautiful, and insightful. Thank you for taking the time in posting the video, and all of the information!

The beach is so cold and windy. We would park on the beach with a bottle of wine, cheese, fruit, and of course sour dough bread and picnic in the car.

Oh my god! I love this!

Decades ago l watched a “Night Gallery “ episode titled “Camera Obscura” which had a camera obscura like the one shown in this video. I thought all camera obscures were like that.

I remember the amusement park on the beach and the roller rink. I see the laughing fat lady with the freckles and the pigtails was preserved. I wish people could see how the camera works and how realistic it looks, like you could grab the seagulls or touch the people walking on the beach. So sorry to hear that the cliff house restaurant was closed in 2020!

How large is the “pinhole” in inches?

[@coolguypravara]

Magnificent 👏.But how the image is getting projected ? Using a lens?

[@redfightblue]

Yes, the diagram at 1:13 shows the light entering horizontally at the top (the pinhole). It is reflected 90 degrees straight down. Then it passes through two glass lenses and down to the table.

[@coolguypravara]

Yaa... I got it now. There is a mirror on top at Pinhole and the light getting reflected on to the lenses. Great 👍. Thank you 🙏 for your explanation and the help to understand the technique behind Camera Obscura 🙂

Damn thought this was gonna be a song lmao

Long before technology appeared, one could conduct surveillance of the surroundings.

[@camazotzz]

Bay area Native Americans had a telecommunications system, all around the bay they built giant shell mounds, from San Jose, SF Oakland and Marin. People would stand up there and using fire and a blanket they would flash a sort of morse code to each other, the message would be conveyed all around the bay so everyone knew what was going on.

illuminati again

Research Leonardo da Vinci lady with an ermine, click on ermine after reading about the art and youll find out that people have been around forever pretty much with technology to remove trees and genetically modify species. Also leonardo da vinci and other artist used the camera obscura (probably a real camera with color and everything) try to find who made clothes for people like queen victoria and before and look at the clothes the kings and queens were wearing. Look at how queen victoria aged over the years. How did people really know where to go and how long it took them with stagecoaches and boats no gps. Who built those roads. Look at adam weishapt death mask and compare it with george washington on the dollar bill. He was going to colleges in the new world but who built those colleges ("minorities" including native americans) and how'd they get so far with the transportation they had. When they stole america 90% of native americans died of diseases spread by the WASP but the whites didnt die of them (biological warfare) or they really just shot them all. They've been lying about everything the United kingdom rules the world including the US. Look up WASP and Harriet tubman story you should realize it's fabricated no one would quote a slave and if she did "cross the line" after the underground railroad she for sure isn't coming back for 70 slaves whether it's all at once or not. She probably was snitching on slaves planning to escape. Who celebrates a slave escaping and look how they treat immigrants today. They were immigrants they stole this. People got the illuminati wrong I think

Jesus Christ, you guys really need to stop smoking all that meth and binging on hair-brained conspiracy blogs.
