Been on this planet 47 years, countless hours in science classes... and in 21:04 i finally "get light" and how it relates to photography (which is a bonus)!!! I'm voting Tony Northrup in 2020

Keep bringing the science. We nerds salute you!

This is the reason why I love this channel. No other youtube channel really digs deep into the science of photography. Great stuff! Keep 'em coming.

Yeh, it gets real messy / interesting once you start digging deep ... the deeper you go, the more freaky things get. Thank you for the great video, keep doing nerdy stuff.

The nerd-videoes are the best. Also I now understand Moiré.

Best presentation on this subject EVER. and I have been a photographer for seventy years..

Pluto isn't a planet, purple doesn't exist... Life is ruthless! 😭

Vsauce: this is not yellow Oh wait, wrong channel

Haha love the big NERDY WARNING!! I enjoy these videos, looking deeper into the workings of our cameras. Thanks for all the effort and research put into these, it's appreciated ☺

What impressed me the most about this video was the fact that you were able to draw an X-Trans sensor array by heart. I've been a fuji geek for about three years now and I can't do that.

5:43 Blue has the highest frequency in the visible spectrum. I think Tony made a slip of the tongue there

Great video, Tony! Allow me to nerd back on one important area this pertains too, astrophotography. As an astrophotographer, I've seen this explanation many times, but it was neat to see it from a daylight shooter's perspective. The Bayer matrix and the reduced light gathering per photosite is the main reason why most astrophotographers switch to mono cameras eventually. At that point, we put red, green, and blue filters individually over the mono sensor to gather more light for each channel and combine them in post. Since our targets don't move quickly, this can allow for much greater resolution on the final image and less total imaging time. We're still blocking light when using those filters, so we also shoot luminance, which is mostly unfiltered, which is why I thought the RGBW matrix you described was really interesting. It essentially allows the color data to be mixed with straight luminance at higher sensitivity, which is what the best galaxy phototographers do now, but all at once! You still have the resolution loss, but you get a big light gathering/detail/noise reduction boost. I could see those sensors being the #1 choice of CMOS astrophotographers once they get built into an astro version with cooling and computer control.

Nicely done. I had seen representations of the Bayer charts before, but never understood why half of the photo-sites were green. Having provided this clear explanation of light, how we perceive it, and of the state of technology for the handling of light, you deserve a relaxing sit-down with something purple, cool and bubbly.

I enjoy your videos exponentially more when you become all scientific and dive to the core of the subject! Amazing video! Nice Job!

Truly love these Nerdy videos. Love geeking out to this type of stuff. Really great to learn more about the inter workings of a camera. I had no idea how the image/light was captured. Thanks Tony.

Thank you Tony, for making complex information understandable! Great video.

Amazing, well done Tony 👍 really enjoy when you break down the science

Thanks for a great CLEAR exposition.

You guys produce excellent videos...thanks as always for all of your content!

Very impressed by your art of teaching such technical subject ! Keep going.

Killer video! You do a damn good job at taking a complex subject and teaching it so everyone can understand. That’s a serious gift bud...Bravo and strong work! 👏🍻

I keep learning a lot from you both. Thanks for the good work!

Mega interesting stuff. Always fun to learn and dig deep into this. Thanks Tony!

I love your mindful decision to do this in a sit down chat/whiteboard format. It really connects. Keep it up T&C!

Another great detailed video Tony!

Fantastic Tony

God: how nerdy can you get??? Literally nobody: Tony: Yes

I love your nerdy videos the most. Amazing! So well explained, keep it up.

Mega good. Thanks Tony.

Loved the way you linked the concept of cones and rods in eyes processing colors to the way sensors capture colors.

This video was just incredible. As a biologist I am really proud to see you accurately using biological examples to illustrate the ability of the camera/us to see. Love it, please keep doing more of this!

If we had as many green cones, but increased the number of red and blue cones to be equal in number would we see roughly the same even if it might be wasteful as far as useful information is concerned?

I know this information is accessible in various places. But having you aggregate and present it in an easy to comprehend manner does the community a great service. An educated community elevates the field as whole.

Tony this was a fantastic video. You are a great educator and I for one would love to see more of these type of educational videos. I know they really don't help to pay the bills but they really are enjoyable to watch.

I love these technical videos! Please keep doing them Tony!

Some folks will be wowed by the end result > the what (the photo/video), some folks will be wowed by the how (the tech) and last some folks will be wowed by the why (the science/explanation behind the tech). It's great you create content that appeals to all three. Well done.

Great Video Tony !!! Thanks.

Great video Tony ... I love when things are explained down to the full extreme level !

Was that over 21 minutes?? I didn't even realize. So, glad i watched it.

I love your videos. You have a knack for taking topics that i have a mild interest in, but not enough to spend hours researching, and condensing it into a digestible, hugely educational 20min video.

As usual you guys provide great information. Thx.

This is the best kind of videos of your channel, please keep geeky Tony

These videos are great! Allows for a greater appreciation of complexity of the equipment we take for granted!

Very useful stuff! Thanks Tony

This is reallly good. I love this stuff. Thanks so much for including this type of content in your mix. I enjoy it all.

A fact that is relatively complex for non-physicists is explained well and simply. Congratulations.

Great video tony. Is interesting to see what goes behind the beautiful pictures.

it is really good explanation of frequencies of light! Thank you Tony!!!!

BLOODY INFORMATIVE video Thanks Tony...

loved this video, thank you so much for sharing

Very helpful. Thanks Tony.

Really enjoyed that Tony - well done! :)

Thanks Tony, very informative video!!

Great geek out! As a fellow science nerd, I appreciate the research you did to put this video together. Great job! It's funny how our entire world is really just in our head. We have no direct input from our senses. Holographic universe maybe? LOL

Absolutely love this, you’re fascinating when you get nerdy.

Love what you do Tony

Love this nerdy stuff! Keep more coming! I like you warning users that a video is nerdy so that those who have no interest in that content can opt to avoid it, while the nerds amongst us can dive in.

Wow I missed these videos and probably this is the best of the best. Thanks Geeky Tony

One of your best videos. This was excellent. Good work Tony

Great Video and Info Tony. Thanks

This was just great ! Would love more of these kinds of videos!

I love these type of videos. Thanks man 🤙

Love it! Pointing friends to this video. Thanks, Tony.

I just found Tony’s nerd videos and I am a fan! As a quick aside related to the beginning where he said the brain assigns colors to different wavelengths of light, it is interesting to note how language is extremely influential in shaping what colors our brain has at its disposal to which to assign wavelengths. For example, words like “blue” “green” and “teal” dictate at what wavelength a color stops being blue and starts being greenish. Most interestingly, brown is not even a color: it is just dark orange; but since it is so common and we have a separate word for it, we consider it a color and can tell the “difference” between brown and orange even though this is not the case for any other color e.g. dark blue is still blue etc.

That's a great job of explaining it all. Can't tell you how many people think each pixel is a single photosite, and your coverage of that point is superb...

Very interesting video. Thanks Tony!

Thanks Tony! Great, understandable explanation of a complex topic.

This was awesome. Probably some of my favorite content on youtube right now. Please do more

I dig this nerdy stuff deep, oceanic sima black hole crazy deep. Just can’t get enough. Keep them coming Tony

I’m and EE and I love the nerdy parts of photography. Given your clout with the industry I’d love to see an interview with one of the technical staff of any camera company. It’s refreshing to take a deep dive every once in a while. I hope you keep doing these vids! Thanks Tony and Chelsea!

Keep up the great work Tony.

Great video! Nice to have every sensor option summed up next to each other like that.

Very well explained !Cleared many doubts.Many thanks.🙏

Loving the book so far, loved the video. Thanks!

This was really great. Thank you. 👍

great stuff.. going to watch a several times to learn ..thanks.

Thank you!!! Great explanation!

Very good video, Tony !

Lovely refresher for me, you put it very well.

Thanks, love your tech videos.

I knew Tony could explain this how I could understand it. Thanks Tony.

Loved this video , thank you 🙏

I like these vídeos Tony. Keep them coming.

I really liked this! I learned more about the way sensors capture color, and why they are laid out that way, than I have from anywhere else. Thanks!

These nerdy videos are great. I knew some of the point but in this video it's nicely put together!

This was incredible! Exactly what I was looking for.

WOW, I love watching and listening to stuff like this. Your a definite nerd Tony.

Informative video, looking forward to the next one!

Useful. Such a good video

It's heavy but very useful. Thanks, Tony!

Best video in months !!

Excellent video!

This is so useful thank you!

Good video nicely delivered. Keep up the good work.

You get a pick, well thumbs up, excellent job explaining!

There were also triple-CCD videocameras with a prism. Each sensor captured a single RGB color. The color accuracy was excellent, but the technology was expensive and complicated so it never made its way to photography. As for now, manufacturers partly solved the bayer problem simply increasing the amount of pixels. Which kind of works - more cells, more data for approximation + you can get rid of aa filters simply because there are enough photo sites per square mm to forget about aliasing in most cases.

@@kilohotel6750 All manufacturers used to have CCD's in their cameras (Canon, Nikon, Sony). They had the same Bayer filter array in front of them. I was talking about triple-chip + prism , where each chip received only one color and no filters were required at all.

thank you for the training 🎉🎉👍🏾👍🏾

Gorgeous composition

Excellent video Tone!

Tony, sir, Hands down, a great video....

Brilliant explanations.
