Hey friends,

Here is a brand new installment of the oft-requested 'CD /' series!

I enjoyed working on this one, but a few parts were real mind-benders to visualize.

Let me know what you think!

Thank you, as always, for your patience and support.

Finally! Another CD / episode! And what a topic!

Excellent as always Cap

Woah. Sooo much work!! Amazing job! (says a pro photographer)

Arto Rantala

This is wonderful. I felt like I learned a lot of new ways to, hm, "see" colour. Thank you! We love you Captain D!

Matt Sims

Great video. Really enjoy the CD/ eps

Oo really helpful. Awesome! The concepts are so easy to understand with your visualizations. I can imagine if I was enrolled on a course for this there would be like 3 hours of people talking at screen about this and drawing on whiteboards, this saves a lot of time and is interesting :)

The first Newton line made me laugh aloud. “This __________....”

Ami Yamato

Awesome, in the literal sense. I'm just in awe of the intricacies of the production. Brilliant.

Oh that ending - perfect!

Rex Schrader

Does anyone have a link to the "random colors" painter experiment describe around 6:00? I want to see the result behind the "spoiler" tag.

Gabe

This is one of your best! Really interesting and beautifully explained and fun.

Fantastic work, I really loved exploring a topic about which I know very little 👍

Cassandra Gelvin

I liked the "How convenient..." with the photo of Darwin.

Excellent video with a perfect ending! This is probably the best explanation on the concept of color that I’ve seen. And it’s quite fun to see how all the sounds fit in after watching the livestream. (Also lol at random German newspaper dissing pre-election Trump)

Great visualization of the luminance waveform! Awesome to see some of the creation of this last week. Way cool!

enjoyed the visualizations; worked in this field for many years and thought this was well done.

I have a question. I thought that human eyes were most sensitive to green light, however the graph with brightness balanced it seems to show green the least and the red and blue ends are much larger, why is this?

Jasper

Super minor correction: the modern hue circle described by Newton isn't actually the modern one (and there were plenty of artists and scientists who had similar theories based on paint mixing). Instead, our modern definitions of hue/saturation/lightness are based on turning the RGB cube on its side to make a diamond shape, turning the resulting midpoint square into a circle to make a double-ended cone, and then HSL/HSV are slices of that cone. Got some other super minor tiny things, but overall a great introduction to the whole topic :)

Kilrah

When you explained the 2 ways of making orange light I expected a "brown light" nod to the Technology Connections video :P

Gene Blalock

I lost it at 3:18! I love it when CD gets frustrated.

Jason Olshefsky

Color me pedantic: it bothers me so much when people (experts, even) don't understand the short/medium/long cones in the eye and claim that red+green == yellow when it only approximates it to humans. Fortunately, I don't have any pedantic issues with your video!

The graph is the how broad in frequency each cone is sensitive, but it does not take account how many rods/cone we have in our eye, and other parameters. Rods for exemple are not sensitive to red light, and are the most sensitive to blue light (hence the use of red light in low light condition to not get dazzled.

David Whitney

"How convenient!" This is actually super helpful as I've only recently started messing with color correction, and it's because of your videos I even knew that was a (major) thing. Night and day difference.

Issac is an actual chad.

Carl Fink

As a nitpicking science nerd, I am required to point out that James Clerk Maxwell, being a Nineteenth Century Englishman, pronounced his last name "Clark Maxwell". And if that's the biggest problem I can find with this video (and it is) you may take that as high praise.

YJ Choi

My jaw dropped when the visual aide of the black and white photo became distorted into a 3D graph while the narration explained that the brighter and darker parts of the image are being plotted and when you look at the graph head-on, that is the pattern produced by the instrument. What an amazingly efficient and effective visual to explain a concept!

You are incredible! Captain D is truly my hero

Great video! Have you talked much about HDR? It seems that 4K without HDR looks worse color-wise than HD with HDR

Dean Herbert

we love you captain D! i've spent hundreds of hours on photo editing, but when it comes to video that number would be much lower. all the while, have always wondered why photo editing software's colour metric displays differ in mechanics from video editing, and while this video doesn't really answer *that* question, i now understand how to read the displays better :)

Ruben Wikhaug

Is it just me or doesn't the i-card work on YouTube anymore, leaving the chroma subsampling effect not lead to anything? Or is it just for the unlisted videos?

James Dominguez

Awesome video as always (loved the Chris Nolan gag) but... *shuffles feet awkwardly* ...the plural of medium is media, not mediums. Sorry. *runs away under a hail of soiled surgical masks*

CaptainDisillusion

I disagree 😊 According to INTERNET, it can be mediums or media, depending on context, and in this context, either is acceptable. We already use “print media” to mean newspapers/magazines, so I felt it’s better to say “print mediums” to describe the various classes of surfaces that can have images printed on them. https://grammarist.com/usage/media-mediums/

Vision and colorimetry are certainly topics of inexhaustible complexity 😁 I read about so much more technical nuance and about the many artists/scholars who experimented with light and pigments... but at a certain point, I had to make generalizations and omit tons of info to make it work in a short, snappy video. But I suppose I could've tried to expand a bit on the modern color wheel, along the lines of what you said. Thx for the notes.

I feel like I don't have a right to pronounce it with a Scottish accent! (But then again, I didn't seem to have a problem Italianizing Marco Bucci's name toward the end 😅)

HOLY CRAP I'M IN THIS VIDEO

Photo people do seem to prefer histograms, which I didn't cover. I guess it's a matter of tradition. The videographers' scopes predate computers, so they prefer to continue to use their digital equivalents, whereas photographers have only been using these kinds of tools since the digital age. Y'all naturally embraced the newer, trendier kind of scope :)

Zach Hunter

The effect at :38 seconds where the color spectrum turns into a cloth simulation is the coolest! It would really be interesting to see a tutorial on how you go about implementing and blending 2D motion graphics type things with 3D renders like this particular effect! Like, how much of it is done in blender and how much is done in AE? Like when you "zoom into it" at the beginning, does that translation have to happen in both AE and Blender? Or just AE and then you sort of scale and match up the 2d image sequence of the 3d render to fit in that space? So many things to think about...

Super briliant visualization of the concepts! It might be more awesome if the LMS-CIEXYZ transformation could be visualized in a more explicit way to show how the "change of basis" is supported by standard observer experiment, and the chromaticity diagram can be plotted twice, once using CIEXYZ color match function, and once using cone response function. Such transformation will be better incorprated into the storyline before 01:59, such that the RGB vertices can be more suitable representation. It is a pity that this video did not touch on opponent process.

There are ridiculously many discussions on a Chinese Quora copycat website about color theory. One of the users even wrote a Mathematica package for numerical experiments (https://github.com/V7CN/Colorful) while writing a lot of articles about color and HDR things (https://zhuanlan.zhihu.com/c_1129083002797633536). For chroma subsampling, I also wrote a MATLAB script to reproduce RED cinema camera's example, available at https://juflt.sjhstone.cn/p/sub-chroma/

Billy

Great video as usual! I said "woh" out loud when you described how the waveform chart works, excellent explanation! Not really a fan of the kids saying "we love you" at the end tho.
