阴天 A cloudy day
在这节课中 我们将讨论画一个阴天 In this lesson, we're gonna talk about painting a cloudy day.
看起来不多 It doesn't look like much,
但这是最难描绘的情况之一 but this is one of the hardest situations to paint
因为没有直射光 because there is no direct light,
这意味着没有硬阴影来描述体积 which means no hard shadows to describe the volume.
让我们看看它是如何工作的 Let's see how it works.
我想画一个完全阴天的阴天 I want to paint a cloudy day with completely overcast lighting.
从这个版本开始我需要做的就是 All I need to do starting from this version...
让我把这个保存为多云 Let me save this as Cloudy.
我只需要用直射光删除图层 I just have to delete the layer with direct light.
那我就去这里 Then I'm gonna go here
并去除所有反弹的痕迹 所有的温暖 and remove all traces of the bounce lights, all the warmth.
我要把它擦掉 恢复到正常的天空颜色 I'm gonna erase that and go back to normal sky color.
也许我们可以加上更多的阴影 And maybe we can add just a bit more shadows in general,
因为这个场景中的光线会更低 because the level of light in this scene is gonna be lower.
让我用一种真正的灰色色调来代替这个背景 Let me replace this background with a really grey tone.
我们在这里清除了所有温暖反弹光的痕迹 We remove all traces of warm bounce light here,
所以我们只有来自天空的光 so we have just the light from the sky.
然后我们要去饱和一点 Then we're gonna desaturate it a little bit,
因为我们没有从顶部得到太多的蓝光 because we're not getting so much of a blue light from the top,
它更像是一种普通的白光 it's more of a generally white light.
还是会有点冷 It's still gonna be kind of cold,
这意味着阴影仍然是温暖的 which means the shadows will still be kind of warm,
但它肯定没有那么蓝 but it's definitely not as blue
当我们有一个晴朗的天和蓝天的时候 as it is when we have a sunny day with a blue sky.
在这里 让我们做同样的事情 只是去除一些饱和度 Here let's do the same, just remove some of that saturation.
我需要在这里画一些乌云 I need to paint a few dark clouds here.
污迹对于创建一些云非常有用 The Smudge is very useful to create some clouds,
一些软过渡 some soft transitions.
如果我们真的想推动这种感觉 也许我们可以在上面加一层 If we really want to push this feeling, maybe we could add a layer on top
然后用这样的大喷枪 and go in with a big airbrush like this
加一点雾 and put a little bit of fog
所以感觉今天雾很大 so it feels like it's a very foggy day.
我正在添加更强的阴影 I'm adding stronger shadows.
当然 还是很软 Still very soft, of course,
但要强调场景中光线不多的感觉 but to emphasize the feeling that there is not much light in the scene.
这就是你应该考虑的 场景中的光量是多少 That's what you should think about, what's the amount of light in the scene.
这里很低 很明显 因为没有阳光 Here it's quite low, obviously, because there's no sunlight,
所以没有直接光源 so there's no direct light source
一般来说 阴影会变得更暗 and the shadows in general are gonna get much darker.
就这样 And that's it.
就像那样 你可以得到一个阴天 Just like that you can get a cloudy day.
只是为了给人一种透视的印象 Just to give an impression of perspective
我在这里添加这些形状 I'm adding these shapes here.
别忘了我们的山 And let's not forget about our mountains.
实际上 在这里 我想如果我打开关卡 Actually, here, I think if I open up the Levels...
图像 调整 水平 Image, Adjustments, Levels,
我可以让阴影变得更强烈 I could make the shadows stronger.
当然 我们需要一个非常柔和的阴影在他下面 And of course, we're gonna need a very soft shadow under him
因为他还在阻止光线到达这里 because he's still preventing the light from getting here.
但是你可以看到它是一个非常非常柔和的阴影 But you can see it's a very, very soft shadow.
任何更强的东西看起来都像是直射光 Anything stronger will look like it's a direct light coming in.
这就是多云的天气 That's it for the cloudy day.
像这样绘制漫反射灯光一开始可能会非常困难 Painting a diffuse lighting like this can be quite overwhelming at first
因为它违背了我们对光的所有先入之见 because it goes against all the preconceptions we have about light.
没有定义阴影侧或灯光侧 There is no defined shadow side or light side,
我们必须依靠极少量的黑暗 and we have to rely on very small amounts of darkness
描述形式 to describe the form.
记住要经常练习 Remember to practice this a lot
每次在阴天外出时都要观察 and to observe every time you're out on a cloudy day.
观察你周围的世界 Observe the world around you,
试着弄清楚它是如何为你自己工作的 try to figure out how it works for yourself,
这将极大地帮助你在绘制这种照明时 and that will help you tremendously when painting this kind of lighting.
在下一课中 我们将在晚上画我们的角色 In the next lesson, we're gonna paint our character at night
被灯笼和月光照亮 illuminated by a lantern and moonlight.
