This is one of 18 videos representing lectures on digital photography, from a version of my Stanford course CS 178 that was recorded at Google in Spring 2016. Links to all 18 videos, my slides (in PDF form), and the course applets and assignments are on the Schedule page of the course web site: sites.google.com/site/marclevo...
For convenience, here is a playlist of all 18 lectures, in order: • Lectures on Digital Ph...
Note that the quality of the audio is poor in this lecture (#1) due to an inferior microphone; subsequent lectures have better audio.
Regarding captioning and translation, all of the lectures have auto-captioning enabled. This also enables auto-translation if you switch the captioning language. The quality of this captioning is uneven, and is probably poor in lecture #1 due to its inferior audio quality. People are welcome to help me by captioning these lectures - in English or whatever language they speak!

Finally, I apologize for being unable to field the many good technical questions these lectures are generating, including many that I am receiving through other channels. Given my day job at Google, I simply cannot afford the time. I am sorry!

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.

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'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.

I really appreciate this sharing! I'm a photog & HS science teacher with a geology major, and tons of interests regarding art composition. It's my goal someday in the small rural HS I teach in to eventually teach photography for HS credit. I have been reading so many technical manuals for years on this stuff. How wonderful to find it all wrapped up in a package like this!

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.

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.

@S3l3ct1ve 6 жыл бұрын

Well that or it could be the fact that when the distance is increased, the subjects fall more and more towards the center part of the frame which is out of distortion in all cases. That is why distortions on the person is reducing.

Thank you so much for sharing this!!! One question though - is there any chance it might get close-captioned? Especially the questions from the in person students are mostly inaudible. There's a point about an hour in where someone points out an error on the slide, and we could hear your reaction to it but not what the error was.

@marclevoy 8 жыл бұрын

If you can't hear questions from the in-person students, then neither I think would whoever we hired to add close captioning. Anyway, Googlers from remote offices pointed this problem out to me, and I tried to correct it in later lectures by repeating questions aloud. Sorry about that!

@wardsdotnet 8 жыл бұрын

Thanks... and I found the slides on your website which presumably have the correction that was mentioned. You can make out some of the questions by cranking up the volume but not all of them. Also there are auto-captions provided by KZfaq which pick up some of the semi audible questions.

@andreionisie168 7 жыл бұрын

The mistake on the slide is that it states: "shortest exposure is 1/f", when in fact it should state that the LONGEST exposure is 1/f. The smaller the fraction the longer the exposure. e.g: 1/4 of something is bigger than 1/20 of something.

Its more like conceptual stuff in here you know. I dont think you need a camera to grab this all. But a bit of knowledge about camera or having a phone camera which you can control manually would make it easy.

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.

Hi, does anyone know why multiplying the number of blurred pixels results in the required minimum shutter speed to freeze the moment?

@MrAndrejing 8 жыл бұрын

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 ?

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!

@sibin_peter 7 жыл бұрын

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.
