In this episode, we explore the basics of how a camera works by looking at the Camera Obscura - a model dating back to the 4th Century in Greece. View more at aop.thepublicbr...
Thank you for a clear, and concise, explanation - it was the answer to a "Jeopardy" clue and I had never heard of it, and now thanks to you I know and understand the term.
Whoa! Great explanation and sweet illustrative example. Thanks for the upload. I'm just getting into photography right now and the history/science of this is fascinating.
Its a fig newton of your imagination,,,,these optical delusions. The first pin hole camera gave way to the first pin head photographer. I'm sorry. What was the insuation I didn't make?
The earliest known written record of the camera obscura is to be found in Chinese writings called Mozi and dated to the 4th century BC, traditionally ascribed to and named for Mozi (470 BC - 391 BC), a Han Chinese philosopher and the founder of Mohist School of Logic. And there are a LOT of other people who wrote A LOT of other things about the "camera obscura" well before 1021 AD. Theres a possibility that even friggin CAVEMEN in the Stone Age knew what a camera obscura was and how to make one.
@@dildonius Ancients such as Mozi had misconceptions and theories about how to see in antiquity such as the theory of emission supported by thinkers such as Euclid and Ptolemy, which postulates that vision is based on light rays emitted from the eye. The second theory is the penetration theory supported by Aristotle and his followers, which assumes that light enters the eye through physical images. Ibn al-Haytham opposed the fact that the process of vision occurs through the rays emitted from the eye, or the entry of light into the eye through physical images, and he reasoned that the ray cannot be emitted from the eyes and reach the distant stars in an instant as soon as we open our eyes. He also opposed the popular belief that the eye may be injured if we look at a very bright light, and instead developed a very successful theory that explains the process of vision that it occurs as a result of the exit of light rays to the eye from every point in the object, which he proved through experiments.
Dude, dont waste time with the obscura, go make a career in a radio! :) Haha, but seriously, you have got a great "radio" voice. You definitely could be making some voice overs i think.
No, that is incorrect. The first surviving mention of the principles behind the pinhole camera or camera obscura belongs to Mozi (Mo-Ti) (470 to 390 BCE), a Chinese philosopher and the founder of Mohism. That predates Abū ʿAlī al-Ḥasan ibn al-Ḥasan ibn al-Haytham by at least 1355 years.
@@ramzichouk4080 On the contrary, his words are true that ancients such as Mozi had wrong concepts and theories about how to see in antiquity, such as the theory of emission supported by thinkers such as Euclid and Ptolemy, which postulates that vision is based on light rays emitted from the eye.

I watched like 10 videos about the history of Camera Obscura and everyone was dodging the fact “Ibn Al Haythem” Arab Muslim doctor, philosopher anf a scientist He invented the whole science of Optics, people used to think light come from the eyes but He corrected that and wrote a book علم البصريات The word camera itself come from the arabic word قمرة spelled Komra in latin Give the man his credit and right of recognition
credit should be given to anyone developing science this is the scientific integrity. it is true the Mozi mentioned it, and he deserves to mentioned too. but when you write a complete book about optics and transfer knowledge through experiments and observations and explain them in detail, develop the camera obscura concept to use lenses and demonstrate it to the public then you deserve an honorable mention. credit is due to masters before students. science is about passing your knowledge to humanity and this is what the Greeks and scientist in the golden ages of Islamic rule did. they transferred knowledge to humanity. and giving credit to them shows your integrity in research.
MrZaZa3استاذ_زازع alhaytham was an muslim arab not persian second where did you get that from and how do you know the writer of the comment is arab and what the arabs did to you
first of all, just mentioning the word "camera" gives credit to the arabs... camera is taken from the arabic word : "qomra " which means " the little sealed room. second if you want to transfer knowledge in a book , you are going to need these: ABCDEF.... which are a syrian invention.... third if you want to do maths, for sure you are going to need these: 0123456789... +-*/ which are a moorish invention....
If you really go to see, the first 'photography' thought should be accredited to the person who understood reflection and made mirrors. Might not be the same person. Once we started seeing ourselves, we wanted to keep ourselves preserved.
Three ways to manipulate light: 1) reflection, 2) refraction and 3) projection. But what is the difference between refraction and projection? A lens and a hole does the same: project an image. So, 3) is somehow embedded into 2). Can anyone comment on this? Or explain? Much appreciated. :)
@@TONE11111 Thank you. In the meantime I thought more about it. What you write makes sense. For a larger pinhole diameter the projected image becomes more and more blurred. So to speak the 1:1 point mapping (object plane --> focal plane) is destroyed for larger entrance diameters of the pinhole. The lens (refraction) restores the 1:1 mapping and sharpens the image.
So how do i take the physical picture then. I have seen Pictures of Rooms with pictures upside down in a room. So i wanted to try and do this. Please help!
"Camera Obscura" was a short story by Basil Copper. It was part of several short stories compiled in one book and presented by Alfred Hitchcock--"Stories That Scared Even Me." I read this story long ago as a kid and it was quite scary, about a doomed and damned soul. Be Warned! Be Careful, when using this device! Are you a good guy? For YOU could be trapped for all eternity inside the Box of the Damned!
As in, what grade do I have? I'm in segment 2 now, I saved it for summer and I started in July... and I'm still dragging it out... I'm in 11th grade, though tee hee
@whenak: Why would it matter what religion (if any) an inventor subscribed to?! Particularly when the technology they have invented has nothing to do with their beliefs. i.e. Do you know the inventor of the grilled cheese sandwich was a Baptist? Get over yourself.
I'm halfway done with module 2. Hey, when you're done with the photography assignment, send me a link to all your photos :D (good site= imgur dot com, as long as each pic is not bigger than 5mb I think) :P I'll do the same for my set of photos the next time :D I'm also taking Drivers Ed btw
@nickpartyka Yeah, I got it when I was 16. I'm 26 now. I would've been 15 when I wrote this comment. I actually never did drive for the longest time. I was terrified of driving. I tried and crashed in 2018, and I was again too terrified to drive for a while, but around May of last year I contacted my original Drivers Ed teacher and he helped me regain confidence. Now I can drive confidently! I'm still working up my courage for highways but I'm getting there :3
@@nickpartyka And I'm judging by this video I was taking Creative Photography? I actually have an Unsplash profile now. I barely use it, but I have one photo with over 7 million views :D
Optical Illusion: "something that deceives the eye by appearing to be other than it is." I mean unless you believe a mirror is a separate universe I'm pretty sure you get what you're looking at is a reflection. I guess it's subjective, but most people I know understand a mirror/a reflection and there usually isn't anyone trying to convince them that their twin self is on the other side peering out at them from an alternate dimension :).
McD Yeah, that’s what an optical illusion is, but they just are that way, nobody is specifically making them (not always) to deceive you, like if you put a pencil in water and look at it at an angle, nobody intends that to happen, that’s just how it works.
This secret needs to be shared 💯 people now who quit art because they couldn't match up with so called professional artist like davinci, dali. Etc this is basically cheating and not real art
I am not a photographer, just have late night thoughts lol. This is by far THE BEST and most comprehensive explanation I have seen. Thanks !
You really explain things very well, although I am a bit stoned right now I still completely understand what you are saying!
MrLetrap im getting high now nd though this niceee
i was thinking the exact same thing while high
Hahahaha same 😂
exactly what i was looking for- thanks for the good video 15 years later!
Thank you for a clear, and concise, explanation - it was the answer to a "Jeopardy" clue and I had never heard of it, and now thanks to you I know and understand the term.
thank you so much i’ve started to read the history of cinema and that really helped me
All the very best👍
there is a huge camera obscura at Ocean Beach in San Francisco. Very cool!
Whoa! Great explanation and sweet illustrative example. Thanks for the upload. I'm just getting into photography right now and the history/science of this is fascinating.
Extremely informative, and instructed at a great pace. Thanks for the vid!
Thank you so much! I’ve been having trouble grasping the concept of this and you helped me tremendously 😊
Dec 2008 omg! I didn't even have a computer back then, and I had my mother's Kodak film camera.
The consistency in quality is unbelievable.
Mozi (470 to 390 BCE), a Chinese philosopher, was the first person to document the principles of the pinhole camera.
searching for camera obscura through google and I stumbled on this video :D it's really refreshing to watch one of your early video :)
thanks for all the great work you have done. im going to watch all of the series. great info on the camera obscura.
Haha, loving the subtitles! Eg. He says: It's the opposite through the pin hole. Subtitle says: See office into the panel...
Awesome video, you make my day.
Keep creating vid, need more like you.
Great video. I will watch the rest of the serie :)
I get it now! Thank you for the helpful explanation.
"Optical aleutian"! These subtitles are gold!
Its a fig newton of your imagination,,,,these optical delusions. The first pin hole camera gave way to the first pin head photographer. I'm sorry. What was the insuation I didn't make?
well said thanks for the simple and clear instruction
Thanks I was wondering how it was working,I will make one for the next eclipse!
Love this..!
Helpfull video! Thanks

do not forget ibno alhaytham first inventor
this should be called The GOD Of Photography!
Great explanation of the camera obscura. But I had to laugh at some of the subtitles: "...being able to record an image onto animals."

You look so young in this!

Yes, they hide the truth because they are fools

wow, uploaded in '08
Anyone else in FLVS Creative Photography and has to watch it? :D
So how do you go about getting a clear bulb?
Thank you!
I feel like Rachel Green: "I don't see it!!"
I've been procrastinating. Just finished Module 3. lol
what up with the cc?
Where did you get that light? It is so unique!
I just started the second module :P
Holy sh*t! Ted had hair!
Can this beat ghost?
He didn't give Al Haytham credit.
No credit due. See Mozi.

a movable refracting lens allows different focal lengths to sharpen or reduce blurring.

nope, I'm not XD
its 2019 already.,., ^^ hahaha.,.,. super late.,.,
(Ibn-Al-Hytham) is the guy of invented the camera obscure in the golden history of islam. history is important
So no mention of IBN Haitham!?
Also don't forget the Egyptians when they images of the pyramid upside down from holes in the pyramid or something of that nature
So how do i take the physical picture then. I have seen Pictures of Rooms with pictures upside down in a room. So i wanted to try and do this. Please help!
Put photo paper in it and wait a while
why do i come here when im high
the intro music is what Liza Koshi uses
I still don't get it.

A mirror is not an optical illusion because there is no intent to make you think that there is a world in there.
What you're actually seeing, a reflection of light, is what is there.
McD That’s not how an optical illusion works
