This is the texture or shader to be filtered.
这是要过滤的纹理或着色器。
Hue[0..360°]
Saturation[-100..100%]
色相[0.360 ° ]饱和度[-100. . 100% ]
These parameters affect the texture’s hue on the color wheel and the total saturation respectively.
这些参数分别影响色轮上纹理的色相和总饱和度。
亮度[-100. . 100% ]
The lightness of the color, from black (-100%) to white (100%).
颜色的明度，从黑色(- 100%)到白色(100%)。
着色
If this option is enabled, the texture will be converted to grayscale. You can then color the grayscale texture using the Hue and Saturation settings.
如果启用此选项，则纹理将转换为灰度。然后可以使用色相和饱和度设置为灰度纹理着色。
亮度[-100. . 100% ]
Adds the values of all color components.
添加所有颜色组件的值。
对比度[-100. . 100% ]
Regulates the overall contrast of the texture. A value greater than 0 raises the contrast, a value less than 0 lowers the contrast. A value of -100% produces a completely neutral gray. A value of 100% gives full contrast between complete saturation and no saturation.
控制纹理的整体对比度。大于0的值会提高对比度，小于0的值会降低对比度。值为 -100% 会产生完全中性的灰色。100% 的值在完全饱和和不饱和之间给出完全的对比。
伽马值[0.1. . 100]
Regulates the mid-tones. Lesser values darken the mid-tones, greater values brighten them up.
调节中间色调。较小的值会使中间色调变暗，较大的值会使中间色调变亮。

These parameters clip or cut colors on two borders. The fastest way to understand how the parameters work is simply to try them.
这些参数在两个边框上剪裁或裁剪颜色。了解这些参数如何工作的最快方法就是简单地尝试它们。
Gradation
Curves
渐变曲线
渐变曲线
The gradient curves can be used to brighten, darken
or color specific brightness regions. 渐变曲线可用于点亮、变暗或特定颜色亮度区域
The gradient curves can be used to precisely modify brightness and color regions of original image. For example, only the dark regions of an image can be brightened or brighter regions can be colored.
利用梯度曲线可以精确地修改原始图像的亮度和颜色区域。例如，只有图像的暗区域可以变亮或者亮区域可以着色。
This can also be done for individual color channels using the separate red, green and blue gradient curves.
这也可以做为个人的颜色通道使用单独的红色，绿色和蓝色渐变曲线。
In the Picture Viewer’s Filter settings you will find a Color Grading function that affects images interactively.
在图片查看器的过滤器设置中，您将发现一个颜色分级功能，交互影响图像。
启用
Use this option to activate or deactivate the graph in the window below.
使用此选项可激活或停用下面窗口中的图形。
强度[0. . 100% ]
Use this setting to define the strength of the Gradation Curve’s effect on the texture. A value of 0% will result in no effect, a value of 100% produces the maximum effect.
使用此设置来定义渐变曲线的强度对纹理的影响。0% 的值不会产生任何效果，100% 的值会产生最大效果。
三原色
Use this curve (in addition to the RGB curves) to define the overall brightness. How the Curve works is explained below.
使用这条曲线(除了 RGB 曲线)来定义整体亮度。下面将解释曲线的工作原理。
RG b
The gradient curve is applied to the linear
grayscale at the left. The result is shown on the right. 左边的线性灰度图应用了梯度曲线，结果如右图所示
A gradient curve defines where a new brightness value will be assigned along the X axis. This is easy to recognize in the image above. The Curve applies a brightness value of 0 to the first third, i.e., black. The second third has a linear gradient that assigns proportional brightness values to the region. The last third has a maximum value, which means it appears white.
梯度曲线定义了沿 x 轴分配一个新亮度值的位置。这在上面的图片中很容易识别。曲线将亮度值0应用于第一个三分之一，即，黑色。第二个第三有一个线性梯度，分配比例亮度值的区域。最后三分之一有一个最大值，这意味着它显示为白色。
This can also be done separately for each color channel, red, green, and blue. This makes it possible to color dark or bright regions only (the histogram in the Picture Viewer shows where which color dominates in the image):
这也可以分别为每个颜色通道，红色，绿色和蓝色。这使得只对黑色或亮色区域进行着色成为可能(图片查看器中的直方图显示了图像中占主导地位的颜色) :
Dark regions in the center were colored red and
bright regions at the right blue. 中间的黑色区域为红色，右边为明亮的蓝色区域
