《01如何工作曲线图》 =====本中英双语字幕由CGSUB.com独家制作发布===== As you may recall, the luminescence of the pixels is its brightness, from black to white. 你可能记得，该像素的发光亮度，从黑到白的。
【更多中文字幕请访问CGSUB.COM】 In previous courses I showed you how to adjust luminescence using the very simple brightness-contrast and the more complicated levels. 在以前的课程，我向你展示了如何使用非常简单的亮度对比度和更复杂的水平调整发光。

As I did back in chapter 12 when I showed you levels. 我在12章时，我发现你的水平。
I'll stand in for the problem image. But this time, I'm too high contrast. 我会站在问题的图像。但这次，我太高对比度。
My shadows are filled in, my highlights are blown out. 我的影子了，我吹出集锦。
You can't fix this kind of problem with levels, but you can with curves. 你不能解决这类问题的水平，但你可以用曲线。
The Curves command takes the histogram, which is that bar graph of luminescence levels from black to white, and scales it to fit inside this square graph, which is pretty intimidating, I grant you. 曲线命令以直方图，条形图，这是从黑色到白色的发光水平和尺度，其能在这个方图，这是非常可怕的，我答应你。
But it means that you can map any luminescence level to another one, which is to say, you have complete control over the brightness and contrast of an image. 但这意味着你可以映射任何发光水平到另一个，也就是说，你在一个图像的亮度和对比度控制。
To simplify things, I'll go ahead and hide the histogram, and we'll focus on this diagonal line Which is the curve itself. 为了简便起见，我将继续隐藏直方图，我们会关注这个对角线是曲线本身。
I know, it doesn't look like a curve, but it will in a moment. 我知道，它不会看起来像一个曲线，但它会在一瞬间。
The current state of the image is the horizontal axis with black on the left and white on the right. 图像的当前状态与黑在左边和右边的白色水平轴。
The modified state of the image is the vertical axis with black at the bottom and white at the top. 图像的修饰状态的垂直轴与黑色的底部和顶部的白色。
So this straight diagonal line indicates no change, black is black and white is white, same goes for everything in-between. 所以这斜的直线表示没有变化，黑是黑，白是白，同样，一切都在两者之间。
Of course, you want to make a change, that's why you're here. 当然，你想做出改变，这就是为什么你在这里。
Which means you need to set a point on the curve and drag it to a new location. 这意味着你需要设置曲线上的点并拖动到新的位置。
Let's say, I want to brighten my mid-tones, I'd click to add a point to the center of the line, then I'd drag it upward, now we have a curve. 比如说，我想让我的中间色调，我点击添加一个点的中心线，然后我就往上拖，现在我们有一个曲线。
My medium grays become brighter but so do all the other luminescence levels in between except for black and white, which remain fixed. 我的中灰色变亮但这么做其他所有的发光水平之间，除了黑色和白色，这仍然是固定的。
But the mid tones really aren't my problem. 但中间色调，真的不是我的问题。
【本字中文幕由 ACELY 翻译制作】 【请认准唯一发布站www.CGSUB.com】 My problem are the shadows down here and the highlight up here. 我的问题是阴影这里的亮点在这里。
So I'll set a shadow point here and then I'll drag it up. 所以我会设置一个阴影点了再拖起来。
Notice that elevates the shadows. 注意，提高了阴影。
The mid-tones are protected by this point, and then the highlights bend down, but only slightly. 中间色调是通过这一点保护，然后集锦弯腰，但只有轻微的。
We need to darken the highlights more, so I'll set a point here, and then I'll drag it downward. 我们需要让更多的集锦，我会设置一个点，然后我会把它向下。
Now we have an inverted S curve, and look at my highlights and shadows, they're in way better shape. 现在我们有一个倒S曲线，看看我的集锦和阴影，他们在更好的形状。
