Thank you Marc. Much appreciated.
Thanks a lot for sharing such excellent technical information. I have just gone back to my college days learning about 2d animation drawing classes when i am with Perspectives 🙂 but it just helped me again to recollect those very important points to keep in mind.
THANK YOU THANK YOU THANK YOU
Since the sites.google.com site seems to have some bandwidth limits and the lectures are here on youtube as well, maybe add links to youtube on that page so people can find them more easily when the maximum has been reached?
Thanks man, you rock!
Thank you for being so generous.
You remind me so much of my favorite teachers. Knowledgeable, enthusiastic, and inspiring 😀edit – And you have way better slides!
Completely useless to anyone like myself who has a hearing loss and requires captioning. Seriously, Mr. Levoy, professor at Stanford and now at Google, and you don't understand the importance accessibility? Fail.
Auto captioning is not captioning, as anyone who depends on captioning can tell you. I appreciate the intent but the reality is that there are millions of people in the US and worldwide who can't hear, and many of them are presumably into photography and could have benefited from this information.
I cannot express how grateful I am that you have shared these lectures. Finally having the the "Why" behind the "How" after decades of studying photography is exciting. Your series should be subtitled "The Missing Lectures" since you provide the science, formulas, and explanations unavailable from every other source I have ever found. I am eager to pour over each installment in your entire series. Thank you, Marc Levoy!
I'm sorry for sounding upset, but I honestly feel that someone with your obvious talents, intellect and experience would have thought of accessibility right away. You must certainly have had students with hearing loss in your classes over the years?
There is currently NO available form of captioning on any of these videos, automatic or otherwise.
I applaud your not charging people for content – but if people can't understand it, then it's still useless to them. I was looking forward to learning from you and disappointed that I can't do so.
Mabuhay! Thank you Sir, this is very helpful, i'm new to photography and this lectures will be a big help. From Manila, Philippines.
58:00 Leaf shutters is slow? You mean old type leaf shutters I guess? I thought leaf shutters is fast. For example, Fujifilm can freeze flash photography up to 1/4000s with leaf shutter on a modern camera, without need of "High Speed Sync". 1:09 Just adding info. If you lock mirror up, it becomes a full electronical shutter on dSLR in most cases.
Mr. Levoy, will a cropped sensor camera like nikon d3100 affect the aperture just like focal length? I mean, do we multiply like say f4 by 1.5 to get the real aperture ?
This is fantastic. Mr Meeker would be proud.
Thank you for sharing this !!!Regards from France.
The sound is sometimes muted sometimes loud.
Thanks for sharing. May I ask where can I find the slides for the lecture?
Many thanks ~
(2:45) I am Batman!!
Hey Marc, I have a minolta srt 101. Do you like it?
This is great!! Thank you for sharing <3 !!
Update on September 7, 2016: the video for lecture #5 has been edited to remove copyrighted content (a short snippet of Alfred Hitchcock's The Birds), and re-uploaded. If people have created playlists of these lectures, they should update them accordingly.
Here is a playlist of all 18 lectures, in order: https://www.youtube.com/playlist?list=PL7ddpXYvFXspUN0N-gObF1GXoCA-DA-7i
Thank you so much for this wonderful service Professor Levoy
Thank you for this contribution to society, it is very much appreciated!
Thanks a lot Professor !! I was not aware of perspective view before. Architecture knowledge can aid in photography :). Thanks for sharing the knowledge for free . Appreciate it very much.
Subject looks to be good. The drawings and and voice have to be improved a lot. Normal ear phones are not good enough for this audio. Thanks professor. As a disability activist, I hope u include accessibility features too.
Well, I guess you dont know the answer to my question Mr. Levoy. And I thought you are an expert on these things. Anyways, thanks.
Thank you. These lectures are great.
All I can say is, thank you!
Hello how it goes. I would like to see the videos, but I can not be in English. You can enable automatic translation of youtube to get an idea of what you're saying? I appreciate it a lot.
I have a question about the focal lengths of lenses for micro 4/3rds that you mention in an answer at ~54.11 minute mark. You mention that the micro 4/3rd lens is 14-45mm. And that this needs to be multiplied by 2 which gets the 28-90mm.
My understanding based on what I have read up online before is that focal length of a lens doesn't change irrespective of the sensor size since it is the actual distance between the sensor and the lens. What changes instead is the equivalent field of view. So the 14-45mm lens on the micro 4/3rd sensor has the equivalent field of view as a 28-90mm lens on a full frame 35mm sensor.
I apologize if you have addressed this issue either later in this lecture or one of the following lectures.
Having been into photography for a few years now, I am really enjoying the technical side of this lecture and am having a lot of "Ahaa.. Now that totally makes sense now!" moments.
My only gripe is with regards to the low audio in certain sections as mentioned by a few of the other folks as well.
sub español please!
Where is the PDF? For some reason I can't locate it.
Hello, could someone tell me how to translate it to Spanish ? … Appreciate it because I am very interested to learn about photography direction through these classes. Thank you 🙂
I think the gentleman asking about the nikon electronic shutter is referring to global shutter. Both rolling and global shutters are electronic. The mechanical shutter is just there to ensure the part of the sensor that has been activated electronically is exposed only and no other light diffractions are there. At least that's how I think it works. The reason global shutters have not picked up fast is the sheer data that needs to be written to cards (16-bit RGB RAW) when all data comes at once. The buffer size of cameras are picking up steadily so I expect this to change.
Thanks heaps for these.
Thank you for sharing so much knowledge! great lectures, still on the first one and already i fell in love with this course. This coming from someone who already has profesional experience as a cinematographer/photographer. Again thank you for sharing this with the world.
What is the question asked in 1:04:20 ??
Quiero subtitulos en español, por favor. Me interesa mucho.
Shame the sound quality is so poor.
I don't own a Camera but kinda passionate in photography. Is it worth watching for me without having a cameras???
Hi Marc! Thank you so very much for this course. You have no idea what this mean for a guy like me who's always wanted to attend a course like this one. Much love brother!
Thank you very much for the wonderful lectures, and more so the upload!
Thank Professor from Benin (Afrika ) !
You rock professor Levoy !
I love you… you are awesome.
I have enjoyed the video I've watched so far, and look forward to the rest of the series. As others have noted, it is often hard to hear the speaker. I think this is because, when he is speaking towards his right, he is facing away from the mic, which is on the left side of his open shirt. This could in principle be solved by making a transcript, an amount of work that is not likely to be done! The other issue is hearing the audience questions; this could easily be solved if the speaker repeats the question. I'd like to suggest that, if these are ever taped again, the questions be repeated and that he takes care to speak directly into the mic.
Thanks for what looks like a very informative series!
thank you for sharing it with the world. Greetings from France
Thanks you from France
hello profesor, can i ask something? what program are using to do your recording
Inconsistent and low audio levels a real drag. (:-(
thanks ,very useful
struggling here but thank you for sharing – greetings from Jakarta Indonesia
Thank you very much Marc for sharing your knowledge with the world. The content is very instructive and inspiring. Greetings from the Grand Duchy of Luxembourg. Jerry.
Hello, Mr. Levoy. Would you also recommend the 9th or 8th editions of Photography book by London, Stone and Upton? The newer versions seem overpriced. Thank you.
Im only about 50min into this lecture but I just want to thank you, Marc, for uploading this. I definitely have a new appreciation and totally different perspective of the camera and photography. Again, thanks a bunch for these lectures
At 1:05:38 you mentioned by counting the number of blur pixel on her finger (which you mentioned it is 5 pixel here), we can figure out the requited shatter speed. My question is, how we can count the number of blur pixel?? 🙂
What were the books?
That Nexus product placement tho 😀still very good and interesting lecture!
I've watched all the videos in this great series. One aspect I really enjoyed, being a scientist myself, is Marc's open-minded attitude and willingness to be corrected and informed by others in the audience, as contrasted by the all-too-common stance of "I'm the expert here, trust me". It exemplifies one of the many pleasures of being in science.
Thank you for sharing. Precious.
First thanks for the videos. However, for a teacher it is so annoying to hear you saying in 1 hr over 100 times…ah.! ah.! and the moving back and forth with no good audio on your phone that I quit listening to your videos on photography. you need a class on public speaking.
Seriously, who could dislike these videos? It's awesome.. thanks a lot for sharing!
Hey @Marc Levoy. Would this lecture be worth it for a student of filmmaking? This would primarily be as a study in technical cinematography and not as still images. I would think it would be applicable since lenses and cameras are the same.
I'm so thankful for your plethora of knowledge and willingness to share.
MAAAAAAAAAAAAN !! where were those courses before ?? Thank you so much
The sound technician should be fired. Impossible to hear the lecture!
As a computer vision practitioner and photography enthusiast, I must say this course has just the optimal balance of content. I watched all the lectures as if they were a TV show, always trying to imagine how the next topic would be presented. Thank you so much, Prof. Marc Levoy! Very inspiring work.
so good ! thanks a lot !
Thank you for sharing such high quality courses. I learned a lot. I found many answers here and some contents may be difficult if impossible to find elsewhere. I shared the link to the 18 lectures on facebook.
In Spanish? 😔
At an hour in Mr. Levoy talks about the 1912 picture "Grand Prix" by Jacques-Henry Lartigue. There's a nice little piece about the picture with a video of how the shutter worked for anyone interested: http://www.gobelluno.it/2014/12/02/la-velocita-nel-1912-grand-prix-de-la-c-f/
Perfect i want to say thanks more than 1000 times for ur videos Thanks a lot 😍😊😉
He had me at geometry.
Love the series, thank you! Just one comment on this lecture at 51:10 the caption over the portraits mentions Effect of focal length on portraits. But it is really showing the effect of distance. If the wide angle lens was backed up to the same distance as the telephoto the perspective (facial features) would be the same. Of course the face would be much smaller in the frame, so that isn't practical or image quality. But it is the distance from camera to subject that is causing the effect on the size of the nose, not the focal length of the lens.
Thanks, Marc! Would you mind adding the book titles and authors to your description?
1000 times thank you
What are the names of the book he mentioned at the beginning?
Thank you Sir ! Olivier from France
I feel like a student again. Thank you! 🙂
Can someone tell me if i can find this videos with subtitles in spanish somewhere?
I'm only in my second year of high school but I'm very happy you've uploaded these because I aspire to be a photographer and this allows me to understand the whole 'science' behind it and how different angles and all that will affect my pictures. I'm only about 45 min. in and I've been taking notes throughout the whole thing. My school doesn't have a photography class so this should work for me. I of course don't understand everything said but I plan on doing more research outside of these lecture videos. Thank you once again!
Oh my god. Everything makes sense now. Thank you!
Seems a very interesting presentation, but because of the very bad sound it is impossible to keep attention. Too bad.
Appreciated that you haven't put an ad in the whole video
I have just watched 30 mins and I already realised this is gold! I just wanted to know a little bit more about photography (though it's not my field, but it's related), but everything he says is so interesting. Thank you!
Who else went out and bought a Nexus 6p in 2019 because of this course?
Thank you so so much!
tried falling asleep to this but a student coughed in my left ear and scared the crap out of me
really good course, finding it a bit hard to keep up with the formulas and technical stuff, my mind doesn't seem to work that way. lets see if its bit above me or not.
¡Muchas gracias por los subtítulos en español!
I found this after watching the Pixel 4 event.
