晴朗的一天 A sunny day
但是如果我们想让光线从前面射过来呢？ But what if we want to have the light coming from the front?
我们肯定不会这么做的 Surely we're not gonna just do this
因为一切都被夸大了 毫无意义 because then everything is overblown and it doesn't make any sense.
所以我们要做的是 So the way we're gonna do this...
让我把它另存为一个新文件 Let me just save this as a new file.
让我们删除两者中的阳光 Let's delete the sunlight in both.
现在我们该怎么办 Now what we're gonna do
就拿这个环境光层来说 倍增层 is take this ambient light layer, the Multiply layer,
我要清除所有反弹光和温暖的痕迹 I'm gonna remove all the traces of bounce light and warmth.
我要回到正常的阴影状态 没有灯光 I'm gonna go back to the normal shadow situation, no light.
我要按Command+U来选择色调/饱和度 I'm going to press Command + U for Hue/Saturation
让一切变得黑暗 and darken everything.
我们在这里做的是改变曝光 What we're doing here is changing the exposure.
如果阴影是如此黑暗 If the shadows are these dark,
也许天空也会更暗 probably the sky is gonna be much darker, as well.
像这样的 Something like this.
今天还是个阳光明媚的日子 It's still a sunny day,
但这一次我们实际上是在曝光 but this time we're actually exposing for light,
因此 我们在光明的领域看到了更多的信息 so we're seeing much more information in the bright areas.
让我们把一些蓝色的带到这里来 Let's bring some of that blue here.
我仍然在阴影中作画 但这次有很大的不同 I'm still painting in the shadow, but the big difference this time
不是为灯光创建一个新层 is that instead of creating a new layer for the light,
我们将使用相同的乘法层 we're gonna use the same Multiply layer.
让我们达到同样的水平 Let's get this to the same level.
像这样的 Something like this.
现在让我们选一个非常亮的黄色 And now let's pick a very bright yellow
几乎没有饱和 with almost no saturation.
现在我基本上可以去掉阴影了 Now I can just remove the shadow, basically.
如果在乘法层上使用绝对白色 If you take absolute whites on a Multiply layer,
它只是删除了该层 it just removes that layer.
当我打开和关闭它时 你会看到它 See it when I turn it on and off.
拿着这个亮黄色, By taking this bright yellow,
通过添加灯光 我们有效地消除了阴影 we're effectively removing the shadow by adding in the light.
这就是我们暴露在阳光下时发生的事情 This is what happens when we're exposing for light.
阴影变得非常强烈和黑暗 The shadows are becoming very strong and very dark
与光相比 compared to the light.
因为从这里到这里的转变是如此强烈 And because this transition is so strong between here and here,
我们需要一种过渡色 we're gonna need a transition color.
要做到这一点 我会得到一个温暖的颜色 因为我在画皮肤 To do this, I'm gonna get a warm color because I'm painting skin
从这两个领域的价值来看 尽量做到两者之间 and try to have that in between in terms of value from those two areas.
这将帮助我们在光和影之间有一个很好的过渡 This will help us have a nice transition between light and shadow.
你可以看到它不是一个很深的阴影 You can see that it's not a deep shadow,
所以我只是用过渡色作为阴影 so I'm just using that transition color as the shadow.
在这里 它可能像这样击中耳朵 Here it's probably hitting that ear like this.
你可以看到蓝色的影响实际上对红色影响不大 You can see that the blue influence really doesn't affect red much
因为在色轮中红色与蓝色相差甚远 because red is quite far from blue in the color wheel.
在这里 几乎所有的东西都亮了 Here, almost everything is in lights.
这个照明场景更难绘制 This lighting scenario is trickier to paint
因为光和影在同一层上 because the light and the shadow are on the same layers,
所以你需要更加小心你的绘画方式 so you need to be more careful with the way you paint.
我想你应该学会在一层上画所有的东西 I think you should learn to paint everything on one layer anyway,
学会控制颜色 learn to control the color
并控制你的画笔笔划 使事情看起来正确 and control your brush strokes to make things look right.
在这里 我们可能会从这只手上得到一个阴影 Here we would probably get a shadow from this hand.
你可以看到阴影中有更多的饱和度 And you can see there's much more saturation in the shadows, as well,
因为颜色更深 because they are darker.
当然 我们在后台也在做同样的事情 Of course, we're doing the same thing on the background here.
当然 顶面是完全明亮的 The top surfaces, of course, are completely in light.
当然 草地也完全是光照的 The grass, of course, is completely in light as well.
也许岩石下面有一些小影子 Maybe some tiny shadows under the rocks.
我们只看到到处都是硬阴影 We're only seeing hard shadows everywhere.
硬阴影 因为这是来自太阳的非常硬的光 Hard shadows because this is a very hard light coming from the sun.
别忘了你可以使用历史记录回到你以前的颜色 Don't forget you can use the History to go back to your previous color.
我在灯光颜色和阴影颜色之间切换 I'm switching between the light color and the shadow color.
然后我们可以在这里有一点反弹光 Then we can have a bit of bounce light here
用于下向表面 for the down-facing surfaces.
不要忘记移除阴影投射处的灯光 Let's not forget to remove the light where shadow is cast.
这家伙肯定是投下了阴影 This guy here is definitely casting a shadow,
甚至可能在墙上 maybe even onto the wall.
当然 让我们加上我们的小山 And, of course, let's add our little mountains.
就拿这个颜色 把它的值降低一点 Just take this color, lower it a bit in value,
稍微饱和一点 a bit more saturated,
我们得到了一个很好的山色背景 and we get a nice background mountain color.
这种颜色显然非常接近天空的颜色 This color is obviously very close to the sky color
因为我们看到了我们和群山之间的天空 because we're seeing the sky that's in between us and the mountains.
这就是所谓的大气透视图 This is what's called atmospheric perspective.
我想现在就可以了 I think that'll do for now.
如你所见 根据光线照射的位置 As you can see, depending on where the light was hitting,
我们不得不调整曝光量 we've had to adjust the exposure
向查看器显示最大数量的信息 to show the maximum amount of information to the viewer.
在下一课中 我们将在阴天使用漫射光 On the next lesson we'll be working with a diffused light on a cloudy day.
