If only there was a 2x speed button for my classes when I was in college.

Dumbed down beautifully. I applaud you, sir.

I like the speed at which you speak. These ppl in the comments section are annoying. This video really helped me. Thank you for making this.

10:29 Poiinng....... :D
Man this guy speaks so slowly that I had to speed it up 1.25 or the video would have been unbearable
Danial Bass
Its cool to see how similar it is to how an eye operates

okay but how does it actually make an imitation of actual life? I don't get it. I get what you're saying about how life events are reflected in the camera, but how does it retrieve real life events...
Hriddha Nabi Prassad
thanks a lot... that was very helpful :D

Very nice. You've dumbed this down so anyone can understand. I commend you.

ok that's cool for a traditional camera, but how to does a modern digital camera work?
Huggy Bear
LOL ! l was watching how to make Paella, and it brought me here. Now, while digesting how a camera work, at the same time, l am also thinking should l add the the rice first or the broth ?

I've seen and watched many tutorials on photography in the last few years, but, without any doubt, this is one of the simplest and best tutorials on how a camera works. I'm also amazed at how detailed the final drawing was doing it live and that it shows a very good representation how digital photos are taken. Thank you for taking the time and demonstrating your talent to simplify such a complex subject.

Aperture science, we do what we must, because: we can.
thanks for the video man helped me get a B on my science project 
Thanks man, I love how you deliver your information!
Jorge Filipe Veiga
Again very good one! You just forget how to design the pentaprism! Anyway another good one!
Thanks Awesome Video
Ruhul Alam
Great explanation
if this video wasnt here i wouldnt, my HALF background info for my science project, so thx dude.
Emanuel Lucescu
Thanks for helping me understand how a camera works and a lot of other important things

Is it like Photosynthesis? Light absorb
Achilleas Labrou
No information about how focus works.
Wow! Great video! Definitely learned something new! :D
bill foley
This is the best video I have ever seen on how cameras work!!! I also love the low key teaching style!
Miguel D
Great video! I learned a lot of things!
Gurosama Bltch
And how did  they do to make a movie with a traditional old camera if that captured the light. Or did the film cameras work with digital thingies? And how did they find out about the digital sensors?
Excellent Job, just love the way you explain the complected things very simply.
Andrew Bruce
There are so many errors in this - do not waste your time watching

Is this CGP Grey???

So long. Make short
even at 1.25 speed the guy is slow lol
3:13 *softly breathes*

Where is aperture video?
salwa aboelmagd
That was really helpful
J. Francisco Arroba
maybe i elaborated the wrong question... this video explains everything except how the camera captures an image.

Cosmos: A Space Time Odyssey S1E4. Light brought me here at 3am to learn about photography. 😅
Barbara Lee
How does light put an image onto film?  I see light threw my window all the time but it does not copy an image it onto my walls or floors.
Saurabh Keswani
Informative😊 thanx
Bunny Gary
Wow! What a great video
Acid Shot
ok i know all of this but i am interesting for the phone cams when i take closer magnets to the phone they gonna stuck to the cam only why ??? is there electric coil or another magnet ???

He sounds like the guy from khan academy
bug a boo
Tomas Tamulis
BRAVO! Great video,on a gradient explains basics so you can understand
prince Parsa
Very helpful
William Gonzalez
Great video!
even though m a commerce student but i was kinda interested in this n the way u explained even i did not have any problem understanding this .. kudos to you! loved your simplistic approach!
Jim Williams
Extremely simple. Extremely well explained. Extremely informative. Thank you! :) I've got to check y'all out. (new sub)
I thought this was a documentary video or something, it's so long. I'll just go read about it instead. And btw, that sound you make with your mouth in between pauses is what makes this video annoyingly longer.
Great explanation, thanks for the video!
Try. Again.
You forget to write small mirror under main mirror, which direct amount of light to the PHASE detector sensor in the bottom side, amateur.
Nutty NooB
Ppl sayin it was to long but i was interested every second of it! Thank you!
Beris Forde
behind the filter is what matters!!!

Thank you
Your khan right
Ivy Tapales
It's amazing that you incorporated science into this course!
Jaspa Jesta Jensen
In this video you are basically just giving a description of the parts of a camera...and where they are located in the camera and their functions...but you aren't actually explaining how the parts function. What are the parts actually doing that result in capturing and materialising a copied image of what you are pointing the camera at? I get that the first part might be something to do with making a reflection thru the use of the lenses and mirror etc , but how is the reflection (image) actually being recorded/ copied onto the film or what have you? How is the image being perpetually kept? I understand its capturing the image by reflecting it like how you can reflect an image in water or like the reflection in a mirror...but how is the camera freezing that and putting the image onto something permanently?

This is fake

"A*hole". Haha, sorry that makes me laugh. Good video anyway.

have a more interesting voice when speaking to an audience

a hoes or a hole?
Harry Yeung
The focusing screen is missing....

Thanks for the video! Nice sound effects!

I only wanted to watch this one video. But you did such a fantastic and clear simple way of explaining that. I subscribed. Cause everyone needs help at times... Great job
Abdul-Hannan Ahmad
Incredibly simple, thank you
Sahnaz Akhtara
good job
Robert Lugg
can you explain how cameras work. do they capture pictures in frames and play them back all at once?????
vishal konde
Mike Leuluai
thanks mate...nice work...much appreciated :)
This is awesome. I've been wondering how a camera works for a long time. Thank you!
Bobby The Gamer
13:52 no it would burn the image into the film and then they would take the film and do this weird stuff and put it in develop liquid and it would dry the image into the paper. that is the main theme. but this is thing it just does not even need light.
is this ASMR?

great lecture! what about the videos that were deleted from the playlist?
Sweta Das
thanks for sharing this info about camera!
Husni Fareed
Very useful and clear video, really helpful! <(^_^<)
Simple and clear to understand
Bobby The Gamer
11:33 no you just look in the window and see the mirror and that hole was were you would have the image go into so you know what the picture would look like.
Appature science!
thank you that was helpful
very informative. thank you.
M Mn
So helpful! :) Thanks!
Jintao Chen
I like how you present it! Especially the logic behind the elements, thanks!
what is the program he uses
Tanuj Karnatak
i really loved this vedio but you speak little slow
Lilpuma Studios
Thank you
BL4Z Evolve
THX really wanted to know and nowi do
Lee Stevens
With digital cameras I think maybe there's a magnetized magnet, and it somehow records the image. Am I right?
Wow what a video you are amazing!
You only talk about oldschool SLR (digital or film) cameras and range finder cameras, but do not say anything about modern mirrorless cameras. This was uploaded in 2012, where mirrorless were already here.
Jacky Llerena
Is that you kahn academy? Anyways, thanks very helpful ^_^
Noora نورة
Wait how does a picture get onto the film> 4:50
Salvatore P
couldnt the mirror act as a shutter? and how does a video camera work? does the shutter just continue to open and close and they get a long sheet of film and run in through?
thomas crute
Thanks bro. You just helped me do my science assignment
