John Hess deserves some kind of an award for his articulate, accurate and very long description of a very complex set of terms and concepts without messing up. Very impressive!

I'm an electrical engineer (and a photographer) and I enjoyed this throughly. It's not often I see the phrase "P-N Junction Diode" outside of my work. Thank you for a job well done.

Very talented speaker. I can't even explain how to make an omelette this clearly.

I was pleasantly surprised by how good this vid was. I’m an electronic engineer who has made digital cameras. Apart some a few insignificant details this was bang on and very informative!

Totally professional, articulate and erudite. What a tour-de-force. This is the bench mark for anybody intending to record an explanatory video on any subject whatsoever, especially a difficult one like this. I'm not sure whether he was reading a prepared text or improvising as he went along, but either way his faultless delivery without ums and ers, together with the injection of contrast and variation in tone, made this a joy to listen to instead of the usual boring trials imposed upon us by the vast majority of public speakers. Bravo. And sincere thanks.

You just explained basic p-n junctions and camera sensors better than any professor I had in engineering school. Good job.

This channel is and always has been amazing.. I wish you would get overexposed just as much as my photos do.

Great stuff as always John. Really points out the science and engineering that go into this technology, which I think is under appreciated. Thanks for what you do here on this channel!

LITERALLY ONE OF THE BEST VIDEOS EVER ON KZread.

i enjoy how you dont really say any obvious misinformation in your videos. you do your fact checking well!

Man I know all these transistor and diode stuff but the way you explained it is better than most of the tutorials online. That was really great.

OMG. This is one of the best videos I've seen. I'm 54 years old and you make me want to enroll in a chemistry and physics class. I'll be rewatching this video because I really would like a better understanding of camera sensors. Thank you for your intelligent and articulate explanation!

That little speech at the very end gave me the chills!! Thank you for this great video.

This is one of the best explanations on camera sensors. It accurately got to the core functions of each technology without going too deep or shallow. As an engineer with a physics background I enjoyed it, and anyone who has an interest in understanding the technology of devices they use everyday can understand it. It is such an accessible explanation of camera sensors it enhances the magic of the technology rather than diminish it.

I just want to say to John Hess that I really appreciate all his work on this series and it has been a great help to me and my film making. I think it is the best film making series on KZread. Thanks John!!

I have taught this material for many years at an undergraduate photography program in Israel. This video is great, visualising and simplifying a complex subject. Great work John! Thanks.

I've watched many videos to try to grasp the concept but nothing was as clear, articulate, well explained as this. Sir, thank you from the bottom of my heart !

Science, magic, and inspiration? As a studying new photographer/film-maker who only came across this video for (and only expecting) technical info, I say, Yes please and thank you so much!

This is one of the most Comprehensive and best videos i've EVER seen! You basically explained everything we need to know about this sensor WITHOUT over complicating things!

I adore these explainers. They are at the exact technical level I am seeking.
