I think deep down I knew this but not actively enough to understand its implications. Tysm!

i love you so much. i love how passionate you are when explaining this stuff. ❣

Love your channel learning so much! Thank you! 🙏🏻

Not discrediting anything you say here but just to say: 3:00 one caveat there, that should not be underestimated, is, that we (the YT viewers) are looking at this through a recording via a camera which - doesn't *natively* see the exact same way we do (the sensors have different spectral sensitivities) - must therefore make choices for how to render images in a way that's reasonable to us and, importantly, - those choices are largely artistic in nature: There is no One Good Way to do this mapping All that said, even without a camera (say, if you repeat this experiment at home looking into a mirror or something - though beware the mirror bounces back light and so will change the outcome subtly), the patterns will still be there. They just won't be the exact same. The reason light goes more saturated and potentially shifts in hue as it gets closer to the shadow zone comes in two parts: The physics: 1. light comes in spectra 2. peakier spectra are higher saturation 3. non-uniform (i.e. not "perfectly grey") absorption and reflection will unevenly filter spectra 4. if you repeatedly filter a spectrum in more or less the same way, you 4.a. lose light, so it'll be darker over time (it's absorbed away) 4.b. increase saturation, because peaks will grow more pronounced over time 5. This can also account for hue shifts as the spectral peaks may also shift their location through that repeat filtering 6. As an optional possibility, absorbed light may be re-emitted in a different color. That's Fluorescence or Phosphorescence. This will also cause a, possibly more dramatic, hue shift. (In most cases this is a very minor effect as usually re-emission happens in the infrared where we can't see it.) The geometry: 1. Surfaces have a roughness to it. Little bumps and holes 2. light bounces on those surface in loads of ways. Locally it's always reflection and refraction but from far away it'll look diffuse or like scattering 3. every time light bounces, that imprints the optical spectral properties of the material it interacted with, shaping the spectrum of the remaining light 4. because of the roughness, it's possible that light bounces off the same material multiple times - it's briefly stuck in a little hole. So the spectrum gets applied multiple times. 5. Light more parallel with the surface has a higher chance getting trapped in this way so it will on average bounce more often, causing more saturation overall: It's more likely to bounce *because of roughness* than *because it hit the surface,* as, if it follows the surface (disregarding roughness) "perfectly", it will not bounce at all. It has to encounter a sudden unexpected "mountain" that makes it change direction, right? Additionally, to that surface description, you of course also get *volumetric* scattering with quite similar outcomes. Both scattering and absorption are dependent on the material properties, so you can get pretty intense colors that way (the sky is blue due to this dependent scattering, filtering the sunlight. It also explains why it goes red near the sunset; the scattering through our skin also involves a lot of absorption through our blood and the like) But the long and short of it is, that, what you say is true: Light gets darker, more saturated, and optionally (though usually) hue shifted. One thing that's *not* actually a thing (and also not something you say in this video, to be clear) is that bright lights "turn white". I mean we certainly auto-white-balance. But light of significant brightness may remain highly saturated. Like laser light. Cameras don't by default detect this "turning white" either, afaik. I mean there can be *some* cross talk, but it's not there "by default". - The whitening is ultimately one of those artistic considerations I mentioned at the start. We just like our images better that way.

Great video as always. Learning 3D Rendering/Lighting taught me a ton regarding light and shadows for painting.

Brilliant, thank you.

I'm so glad to be alive to see this video! Thank you for making it, brilliant and very helpful! <3

It was helpful!

Another genuinely insightful and helpful lesson! Thank you!!!

an interior designer told me something similar once. she said that the same paint or finish would look different in a room with light coming from different cardinal directions and depending on what objects were outside the window. a big tree or a lawn would cast in a lot of green colour, and that might look cooler in a room with north facing windows during the day versus in a room with west facing windows in the evening, and then adding in multiple windows or doorways, etc. great video thanks!

This is a very precious, enlightening video. Thanks so much!

cool theory, very cool if you make vidio for practice painting this theory. i hope you make it🔥 btw thank you

You are a legend bro.... Sometimes I see myself in you... I don't know why...

Perfect explanation. I was always fascinated by sky blue shadows in the snow

Legendary channel

The ‘there is no color in the shadow but the secondary light‘ things really enlightens me

I spent 5 ears of my life in an art school, but none of classes there were nearly as interesting as yours! Thank you so much! I hope we get to see more of your color theory/painting/etc videos🥺

Excellent tutorial!!! Covered so much as efficiently as possible. I want to know what lighting system you’re using!?!? Incredible demonstrations 👏

Whata awesome video! I MUST marathon your channel

I am a mostly self taught artist looking to find my own path into my desired profession. My dream is to someday make movies and influence people and things through art. I’ve spent a lot of time studying outdoors, the different ways to use colors and how it affects the piece as a whole. When I graduated high school I wasn’t completely sure what it was that I wanted to do but I have found through your videos that this is what I love! Colors and light fascinate me endlessly and I completely admire the way you can use it to set vastly different atmospheres. You’re an amazing teacher! Thank you so much for the effort you put into these videos! I would love to take a course someday but I just haven’t had the time, hopefully one day I can make it happen but until then I am a lifetime subscriber to your channel! <3

Jeremy, you look like you're skipping on your health & fitness activities lately.

Another banger

dang. The blue sky being secondary light source blew my mind a little bit. This was filmed really well and it greatly aided in my understanding of what you were talking about. Having you on screen as the presenter while the lights changed color and you changed environment was a really good choice even though it probably took forever to film. thanks for going the extra mile it really helps.

Would you consider breaking down the lighting technique for korean webcomics? They have to be produced incredibly fast but many times the color and light comes out looking gorgeous and ive been struggling to understand what exactly theyre doing. I can tell theres some sort of baseline method but never exactly whats happening and why

Of course you're from Pixar, seems like that place encourages being open and helpful. I'm almost done with Ed Catmull's book and it is loaded with great advice and information. I've mostly been reading it while rendering, since when I'm doing CG I'm often reminded of him as his name is there every time I subdivide something.

I think I have to watch this video each month so that I don't stop practicing..😒😂

I love Washington state, gorgeous painting!

Apparently the circle of fifths reflects frequency relationships within the colour wheel.

Mix colors in a traditional way and you won't have this problem. Color picker makes you pick the wrong colors.

i just had to click when i saw Dorian in the thumbnail, you guys defo get along for a mutual love for eggs :)

Thank you so much for making this video, I was struggling with this in my new project!

Thank you Jeremy for the content, I appreciate your time and knowledge 😊

What brush is he using?

5:29 RDR2 Flat iron Lake near Rhodes around DuskDown

2:19 help I have this night light-☝️🤓

Geeze, I’m trying to follow along with you, but I find that I struggle so much with the texture of everything. I think this is because I use a flat brush, which I love the flat brush. But, it’s time to try a different one 😅

Cool video, I'll give this a watch later, you got a new sub! 😊

Very helpful Thankyou

This is why my idea of ideal color palette will be like a color wheel but gradually become grey as going toward the center and there's separate handle that control the center value all the way to the black from white.

great video, thanks. Personal feedback: the repeating tune is a bit annoying personally, my only little nitpick

Holy... PURE MAGIC Thank you for this video!

In LLL, we called it 'lovingly lifting' lines.

We learned about color change in art school, but I never understood the extent to which I could use it on my canvas. Thanks!

you changed my life, this was an amazing video

This is amazing

I'm having difficulty applying this to scenes with highly saturated backgrounds. Does anyone know why?

I’ve learned a lot from your videos. Thank you so much

like yur vids but as I have bad hearing trying to hear what your saying, music sets of my tintiness. vocals-no anoying music. what your SAYing is IMportant, your music choices suck....

Casually mentioning that he made ratatouille

I rarely ever write a comment down on KZbin but Wow I must thank you for this video. I truly needed this kind of lecture. I was struggling so much in understanding lighting and making a scene that has story, mood and depth for the last couple of years in my self taught art life... I am very thankful to have known you and your videos.
