14 Lesson 3 - Perfect Color and Light, Each Time Part 3 - Artifitial Ligh P14 - 00:01人造光。?

Nowadays, even at night, nothing is ever fully dark. We have computer screens and desk lamps and street lights and car lights.?晚上很少有漆黑不見五指了，我們有臺燈?屏幕燈?車燈，We have these fake suns just about everywhere.?到處有人造小太陽光源。And just like how our sunlight can completely drown a scene to give it a time of day and also a mood.?如同太陽光不同時(shí)間段渲染一個(gè)場景，給到一個(gè)時(shí)間段，給到一段心情。Artificial lights are the exact same.?人造光源也是同樣的道理。?

P14 - 00:23舉例子。?

Now let's hop into some of the most common sources and understand what kind of impact it can make on the scene. The first is probably the very first source of artificial light in history of like ever, which is candlelight and fires.史上第一個(gè)人造光源是蠟燭和火焰。?Now I'm hoping everyone has seen a fire at least once in their life.?希望各位至少人生中至少見過一次篝火。But it's usually warm and red. Nowadays, though, I guess we can also see blue fires in pink fires and green fires.?篝火溫暖紅色的，現(xiàn)在可以看到藍(lán)色的火苗?綠色的?粉色的。But those are anomalies,?那些都是少見的。unlike with sunlight, where it completely based everything In this light.?并不像陽光可以普照萬物的。All sources of artificial light have a radial effect instead,?所有人造光源都有光源散射的效果。which means. They only affect a certain area rather than drawing the entire scene.你可以看到燭光影響到局部場景，?And our brightest, the closer you are to the source.?離著光源近的明亮，比如嬰兒面龐離著燭光近，母親面龐離著燭光遠(yuǎn)，嬰兒面龐被光照的比媽媽面龐照的更亮。So as you can see, the baby's face is being lit pretty strongly by the candle light. But the mom's face whose face is farther away from the candle light Is little less.希望這常識對你并不陌生，這些都提供可信度。?Hopefully this isn't new to you. But be aware that this is what creates believability. ?

P14 - 01:24主導(dǎo)光源。?

If you have a fire in a completely closed room is light effect will touch everything.?足夠近的光源會照射的附近的物體，最近的面部亮的，遠(yuǎn)離光源的面部暗的。But as soon as you introduce any source of natural light like a sun or a moon, then a fire, an artificial light, will be drowned out by the natural light.?但是人造光源會被自然光湮滅。So make sure you understand which is the more dominating light source each time.?每次需要確認(rèn)哪一個(gè)才是主導(dǎo)光源，是人造光還是自然光。Therefore as you can see here, the light from the window is much more powerful than the light that's coming off the lamp.?本案例中透過窗戶的自然光主導(dǎo)，地面上燈光人造光源次要的。Or in this case, that would be the artificial light source, whereas the window is a natural light source. ime Part 3 - Artifitial Ligh P14 - 01:52勢均力敵的光源。??

P14 - 01:52勢均力敵的光源。?

接下來對普通生活中光，比如臺燈或街燈的處理。The next tackle would be your average light, like a desk lamp or a street lamp. You will notice that these lights obviously have a bit of glow from their source. And the way the light is made creates a light shape. For example, you'll see here that there is an actual umbrella like structure that the light is creating.?你可以看到臺燈做出弧線形，兩個(gè)方向。And it creates a direction going this way. And this way.太陽光源是不會這樣走向的。只有人造光源會是這種走形。?you won't really see this one sunlight ever. But you only see this with artificial lighting.?為了讓人看起來是人造光源，你的作品需要加入光的形狀。To make it believable. You have to make sure that you add this kind of shape inside your painting. ?

P14 - 02:26太陽光強(qiáng)度高。?

窗戶投過來的自然光遠(yuǎn)遠(yuǎn)強(qiáng)過人造光，你可以看到人造光只能點(diǎn)亮自己，對周邊的物體沒有影響。Sun lights will be stronger than others. You can see that here these lights barely affect anything other than themselves. And again, the light from the windows, the natural light is much more powerful than the artificial light which are these lamps here.很難有人造光強(qiáng)度勝過太陽光源的。?It's hard to make any light to feed the sun and natural light is almost always the winner. So that's why there's a stronger emphasis on it above all else, artificial lighting can also go into the hyper crazy category such as in the cyberpunk twenty seventy seven.?人造光源可以無限循環(huán)復(fù)制，比如影視《賽博朋克2077》。?

P14 - 02:56賽博朋克。?

or the cyberpunk genre as a whole really, they love their neon lights which base everything on their strange funky pinks and blues.賽博朋克霓虹燈基于粉色和藍(lán)色。?basically Sci-Fi loves artificial lighting. This is like such as blade runner Godzilla versus call Pacific Rim.?比如科幻小說里的人造光，《銀翼殺手》《哥斯拉》《環(huán)太平洋》。It gives off that super futuristic tech field.?散發(fā)未來高科技的感覺。Also, don't forget,?

P14 - 03:16充滿魔幻色彩的燈。?

magic is also artificial light. Don't think I did forget about magic. The reason is because it just like a lamp or fire only affects things in a radio area. It doesn't really bath things unless you have a sun made out of magic, which is only like could be a thing. But regardless in most cases, magic is also a source of artificial light.別忘記魔幻色也是人造光燈一種，也是局部范圍內(nèi)的發(fā)射光。?

P14 - 03:38人造光不如太陽光穩(wěn)定。?

One thing to realize is that both artificial and natural light can give off say like a green light or blue light, but they will still feel very different. We can change the color of our desk lamp very easily, but we cannot change the color of our sun.?如果人造光和太陽光可能都是藍(lán)綠色。我們很容易變化人造光，但是不容易改變太陽光。If you can do that, please call me. I need to know your ways. But our sun stays a mostly yellow, white or orange red kind of light. So when we see a green scene out in the wild, the light on the characters or the light that is picking out is always a bright yellow or a white light.太陽光打在自然界的顏色是明亮黃色或者白色。?

P14 - 04:15街燈打在人身上的效果。?

so yellow light is hitting the streets here and is hitting these characters here. It's like a yellow, white kind of light. It will always colour the local value towards a yellow or warm tint.所以自然光把樹葉角色局部涂上了黃色暖光。?Therefore it's very different from actually using a green light which bathes the entire thing in green.?再比如綠光燈一切都染成綠色。?

P14 - 04:42繪畫常見的錯(cuò)誤。?

Therefore a common mistake I see people doing well be that they would try to color something. So for example, let's say that you have this super cute photo of a dog and you want to paint it to be brighter.?比如我們把狗涂上亮色。Sometimes what people would like to do, if they want to incorporate sunlight into this painting, all they wanna do is just make something brighter by adding white, which really isn't the way to go. So if you just add white, you kind of just get a brighter picture.?如果你想給照片加入太陽光，你加入白色但是得不到發(fā)亮效果。You don't really feel like there's a warmth or sunlight, but rather not going back to original. If you wanted to add some light into it. Or have a some kind of warm artificial light. And you should add a warm color tint like this. in that way. It will feel a lot more as the sunlight was streaming through the windows. And it feels a lot more of lit overall.?我們可以染上黃色暖光的色調(diào)，如同陽光透光窗戶的光束給畫面染上的色彩。?

P14 - 05:30再舉例子，孩子畫的草地是綠的。?

Think about when a little kid draws grass. Why does it look so fake? When kids draw process green and the sky is blue? Because grass, at least when you look at it in real life, it's not actually green. So if you're just going to colour the sky blue and make the grass green, and something looks really off, the grass actually needs to be a little bit more yellow than that, because when you look at an actual photo of grass, you can see that the sky gives off this warm yellow light and thus the grass should also be a bit more yellow lit. I literally just took the colors out from the image to be able to create this grass that definitely looks so much more believable than what was originally there,?日光下的草不是綠色，是黃色。?

P14 - 06:20夜光下的草是什么色？?

the same thing occurs for the night time. A normal little kid would paint the sky to be looked like a dark blue, and then paint the grass to be a green. But as you can clearly see, something that looks really off about this image. The reason is because the grass really shouldn't be that shade of green. as we talked about before, because it's night time. Our eyes can't really sense super vibrant colors. So everything kind of turns to dark and monotone blue. Therefore our grass actually needs to be colored essentially black.晚上因?yàn)橐曈X難以分辨顏色，所以單一色調(diào)的藍(lán)黑色，所以草是黑色的，淺綠色是燈光打下來的顏色。?And you can see that I have little pockets of slight blue green that pop out every once in a while to make it feel as if being lit. And this grass feels so much more natural than whatever the heck that we did for this one.?

?P14 - 07:11總結(jié)下。?

Which I reiterate, please. By all means use reference in your paintings. If there's a scene or time of day that you don't really know how to paint, just look at mother nature and just look at the photographs. So really keep that in mind. It will make your color and light more believable,?借鑒下大自然的上色風(fēng)格，讓你繪制的充滿可信性。?

P14 - 07:29舉例子如何參考大自然的光。?

such as are you in strong sunlight? Then you should make your blacks warmer, make them more brown. See how the artist Kim English here is making the blacks of this lady just stretch more towards brown,你可以看到Kim English藝術(shù)家繪制夏天陰影棕色的。?or are you in a cool light and the shadows? Then you should make your whites turn into blues, really let it drown in that blue color.?再比如天藍(lán)色襯托陰影里的涼爽。This makes your piece so much more believable. It makes the light believable. And it gives you a piece of vibrancy and beauty.這樣給你的色彩?燈光變得可信度高。?Because to be honest, a neutral lighting setup is actually a bit rare in the picture making world.?真實(shí)世界人造光源覆蓋的圖畫很少見，所以人造光源20分鐘講完了，只剩下燈光如何影響顏色。Now, this was a much shorter lecture to make up for the 20 minute one that you had to wash regarding daylight scenarios. Because artificial light is a lot more simple to explain and comprehend. And at this point, we're not even talking about artificial light anymore. We're just talking about how light it really affects color.?

P14 - 08:15燈光如何影響顏色。?

I totally get it that it can be really difficult to choose colors and know what is what and what is where and what color to put for this what could put for that.? But now that you know all of what I just taught you, take your pieces color and break it down. Ask yourself what is my primary light source? Is it the sun? If so, what's the time of day? And then go ahead and find reference images that correlate to that time of day. Or if your primary light source is an artificial light, think to yourself, how strong is that light? How far is it going to affect the colors of my piece??我了解常常畫畫為了上什么顏色煩惱，如果可以分解步驟問自己，選擇人造光源還是太陽光，如果是太陽光，什么時(shí)間段的，什么強(qiáng)度的，想好后，拿出參考圖來繪制。接下來我舉自己影視場景繪制的例子。As an example. I’ll pull up the pieces I did for the playstation magazine cover for cyberpunk 2077.?

P14 - 08:55自己的案例。?

when I was sketching and deciding what to do for the peace, I asked myself. Number one, what's my main light source? Well, I told myself I wanted to be the sun, I want to come out from behind the character and back like them. okay. Got it?比如我想繪制夕陽西下，從角色背后投射出來。 Then what's the color going to be? Well, I want this piece to be a really warm and kind of paint because cyberpunk is so famous for its pink hues. Since my main light source of the sun. And I want a pink sky and it's gonna be either sunset or sunrise, because the city and cyberpunk is called night city. I will make it sunset. cool. 接下來光的顏色，日升日落時(shí)候，粉色的，因?yàn)橘惒┡罂孙L(fēng)格高飽和度的，And so then I looked for reference images of sunsets, which are right here. 找到夕陽西下的指南，做出夕陽西下的色調(diào)。Then as I take the piece to a finish, I also bumped along small artificial lights on the way, like these holograms and advertisements, here here, here, here, here, here, here, basically everywhere, like these small little artificial lights. 接下來做了幾處全息影像和廣告燈光。So I asked myself, how strong are these lights? And I know that no matter what, they can't be stronger than my main light source or the sun. So i'll just have them affect a little portion of the piece. 人造光強(qiáng)度比不過落日余暉，所以我設(shè)計(jì)的零星小點(diǎn)。So. As you can see, these small lights don't give off too much of the light, and they just affect a little bit of the surrounding area. But the main light is coming right here to my character. And with that, my artificial lights are done. 你看小光源覆蓋的區(qū)域面積不大。主光源來自角色身后的落日余暉。The entire scene is bathed in this semi pink light from a sunset like scene. 整個(gè)圖片場景沐浴在落日余暉后粉色的斜陽。And by breaking the color down to these simple steps and questions,?

P14 - 10:40借鑒光源。?

I have a very solid piece that does not look like a nineties cheap advertisement website. Even though I have a lot of color that's going around and you can do the exact same thing. Don't be afraid to use reference. Mother nature will never sue you. I promise. If she does, I will personally be your lawyer, but that's it. 不用害怕借鑒參考圖，尤其是來自大自然的參考圖。Color is just that as light and colour coming together to wash over your painting in a filter like a manner.如何運(yùn)用好光和色彩如同濾鏡效果一樣。 Now let's take you through a demo to further demonstrate this and show you how you can do it easily yourself.
