用窗口遮罩区域Masking Areas with Windows

1. 打开 DaVinci Resolve 20（如尚未打开），然后打开一直在用的 Conservation Film Company 项目。Go to the color page and ensure that you are using the Conservation Filming timeline, which can be found from the menu at the top of the viewer.
2. 如果进度落后，请从 Lesson 05 文件夹导入 Conservation Primary.drt 文件。进入 Media Pool，在 Timelines bin 上右键选择 Timelines > Import > AAF / EDL…。无需导入则跳到第 3 步。Select thumbnail 08 in the timeline.
3. 切换到 Color page，确认使用 Conservation Filming 时间线，可从检视器顶部菜单选择。This is a panoramic shot of one of the subjects in the desert, but it lacks the punch you would expect from a shot like this. By working on the foreground separate from the desert background, we can enhance this beautiful shot to bring out more colors.

1. 在时间线中选择缩略图 08。On the first node, using the Offset master wheel, bring the level down to around 19.55 to ensure that you have no clipped highlights.

这是一个沙漠中主体的全景镜头，但缺少应有的视觉冲击力。把前景和沙漠背景分开调整，可以强化这个漂亮镜头中的色彩。In the Node Editor, right-click over node 01 and choose Add Node > Add Serial to add a second node.

1. 在第一个节点上，使用 Offset master wheel 将亮度降到约 19.55，确保高光没有 clipping。Right-click over node 02 and choose Node Label, and then name this node FOREGROUND.
2. 在 Node Editor 中，在节点 01 上右键选择 Add Node > Add Serial，添加第二个节点。In the toolbar center palettes, click the Windows icon.
3. 在节点 02 上右键选择 Node Label，将该节点命名为 FOREGROUND。Power windows, or windows for short, are probably the most heavily used features when trying to isolate an area for correction. They allow you to specify which area of the image you want to alter using a drawn shape. The shape can be standard ellipses, rectangles, polygons, or arbitrary Bézier shapes that you draw with a pen tool.
4. 在工具栏中央调色板中，点击 Windows 图标。In the list of windows, click the Rectangle button to activate it.

Power Windows（窗口）是做局部校色时最常用的功能。它让你通过绘制形状来指定画面中需要调整的区域，形状可以是标准的椭圆、矩形、多边形，也可以用钢笔工具绘制任意 Bézier 曲线。A rectangular window shape appears in the viewer. You can resize and reposition it so that it is only over the foreground in our picture.

1. 在窗口列表中，点击 Rectangle按钮将其激活。Drag within the center of the rectangle to move it down so the top sits level with the top of the shadow in the foreground.

Viewer 中出现一个矩形窗口。你可以调整它的大小和位置，让它只覆盖前景区域。Using the white control points on either side of the rectangle, drag to the edges of the frame until the rectangle covers the entire width of the picture.

1. 在矩形内部拖动，将其下移，使顶部与前景阴影的顶部对齐。Use the middle mouse wheel to zoom out in the viewer so that you can expand the rectangle outside the frame boundary.
2. 用矩形两侧的白色控制点拖动到画面边缘，让矩形覆盖整个画面宽度。The center handle inside the rectangle is used for rotation, but there are also transform controls for the window in the center palette. Sometimes, using the controls in the center palette is easier than dragging in the viewer.

矩形中心的控制手柄用于旋转，但中央调色板里也有窗口的 transform 控件。有时用中央调色板比在 Viewer 里拖动更方便。If you need to expand the rectangle after rotating it, use the Size number field to expand all sides of the rectangle.

1. 在窗口调色板右侧，将 Rotate 数值字段稍微向左拖到约 0.85，让 Viewer 中窗口顶部与前景阴影更好地对齐。Now that you have your window in place, any color adjustment you make with node 02 selected will be made only within the area covered by the window.

窗口就位后，只要选中 02 节点，所做的任何色彩调整都只作用于窗口覆盖的区域。Using the Gamma color wheel, drag the center toward blue to give the shadow a cooler feel.

1. 在主调色板中，降低 Offset master滑块，让前景阴影变得更暗，数值大约 10.85。The outline of the window can obscure the edges of the correction, so it can be helpful to hide them from time to time.
2. 在 Gamma 色轮上，把中心点拖向蓝色，让阴影区域偏冷一些。In the viewer’s lower left corner, click the onscreen Overlay button and choose Off from the dropdown menu that appears.

Power Window 的轮廓线会遮住调色边缘，所以时不时把它隐藏一下会方便观察效果。The top edge appears to match the shadow well, but the edge might be a little too hard. It needs some roll-off from the shadows into the highlights.

1. 在检视器左下角点击 onscreen Overlay按钮，在下拉菜单里选 Off。On the right side of the windows palette, drag the Soft 2 number field slightly to the right to expand the soft edge along the rectangle’s top. Aim for around 5.00.

窗口顶部和阴影区域衔接得不错，但边缘可能偏硬，需要在阴影到高光之间加一点过渡。In the viewer’s lower left corner, click the onscreen Overlay button and choose Power Window from the dropdown menu that appears to turn the window back on.

1. 在 Windows面板右侧，把 Soft 2 数值稍向右拖，让矩形顶部的柔边扩大一些，目标值大约 5.00。Clicking off the Window menu in the middle panel to any other tool, apart from the Tracker, will also hide the window in the viewer.
2. 在检视器左下角点击 onscreen Overlay按钮，在下拉菜单里选 Power Window，把窗口重新显示出来。To compare the change you made on node 02, press Command-D (macOS) or Ctrl-D (Windows) to disable the node’s adjustments, and then press the keyboard shortcut again to enable it.

1. 想对比 node 02 上的修改效果，按 Command-D（macOS）或 Ctrl-D（Windows）禁用该节点的调整，再按一次快捷键重新启用。想对比 node 02 上的修改效果，按 Command-D（macOS）或 Ctrl-D（Windows）禁用该节点的调整，再按一次快捷键重新启用。
