窗口遮罩Window Masking
学习目标LEARNING OBJECTIVES
学完你能走完"画窗口 → 验选区 → 羽化 → 对比"的完整遮罩流程，做出看不出痕迹的局部调整。
概念说明CONCEPTS
窗口遮罩（Window Masking）是用 Power Window 画形状、限制调整范围的完整工作流——二级调色中最基础的隔离方法；它的功夫不在"画出来"，而在"让人看不出来"。
- 画到画框外：控制点可以拖出画面边界；需要满宽或贴边时，先缩小检视器再拖。
- 数值比手稳：面板右侧的
Size、Rotate数值字段，比鼠标拖拽更适合精细对齐。 - Highlight 验选区：检视器左上角的
Highlight按钮给受保护区域盖灰，将被调整的区域保持原样。 - 羽化可以分边：矩形等形状的多个
Soft数值各管一条边——只柔化与邻区相接的那条边，其余保持利落。
操作步骤STEPS
- 新建串行节点并命名（如
FOREGROUND），在中部面板打开Window - 选择形状并摆位：需要超出画框时，先滚轮缩小检视器，再拖控制点出界
- 用面板右侧
Size、Rotate数值精修，让窗口边缘贴合目标区域 - 点检视器左上角
Highlight检查选区：灰色=受保护，正常显示=将被调整
- 关闭
Highlight，在该节点上做调色 - 拉大相接边的
Soft数值，把衔接处羽化到自然 Overlay选Off隐藏轮廓线，按Command-D/Ctrl-D对比调整前后
练习PRACTICE
- 找一个前景背景分明的镜头：用矩形窗口罩住前景并压暗，用
Highlight确认选区没有漏进背景。 - 只给相接的那条边加
Soft，切全屏（Command-F/Ctrl-F）检查还能不能看出边界。
常见问题FAQ
怎么确认遮罩到底罩住了哪里？
按检视器左上角 Highlight：盖灰的受保护，正常显示的是调整区；验完再按一下关闭。
窗口拖不出画面边缘怎么办？
先用鼠标滚轮（或 Command-减号/Ctrl-减号）缩小检视器，再把控制点拖到画框外。
窗口轮廓线不见了，是丢了吗？
不是。点检视器左下角 Overlay 选回 Power Window；切去别的面板也会隐藏轮廓，窗口本身还在。
形状太复杂，窗口画不出来怎么办？
两条路：换 Curve 钢笔徒手勾勒；或改用按颜色选择的限定器（见 限定器），再叠窗口做加减。

After this card you can run the full masking loop — draw, verify the selection, feather, compare — and make local adjustments nobody can spot.
Concepts概念说明
Window Masking is the complete workflow of drawing Power Window shapes to limit where an adjustment applies — the most fundamental isolation method in secondary grading. The craft is not drawing the shape; it is making the shape invisible.
- Draw beyond the frame: control points can go past the frame edge; zoom the viewer out first when a window must span or hug the edges.
- Numbers beat the mouse: the
SizeandRotatefields on the palette's right side are better for precise alignment than dragging. - Verify with Highlight: the
Highlightbutton (viewer's upper left) grays out protected areas while the area to be adjusted stays normal. - Feather edge by edge: shapes like the rectangle have several
Softvalues, one per edge — soften only the edge that meets its neighbor and keep the rest crisp.
Steps操作步骤
- Add a serial node and label it (e.g.
FOREGROUND), then openWindowin the center palettes - Pick a shape and position it; to go beyond the frame, zoom the viewer out with the scroll wheel first, then drag the control points out
- Refine with the
SizeandRotatefields on the palette's right until the window hugs the target area - Click
Highlightin the viewer's upper left: gray = protected, normal = will be adjusted - Turn
Highlightoff and grade on this node - Raise the
Softvalue of the joining edge until the blend looks natural - Set
OverlaytoOff, then pressCommand-D/Ctrl-Dto compare before and after
Practice练习
- Pick a shot with a clear foreground/background split: cover the foreground with a rectangular window, darken it, and use
Highlightto confirm nothing leaks into the background. - Feather only the joining edge with
Soft, then go full screen (Command-F/Ctrl-F) and check whether any boundary still shows.
FAQ常见问题
How do I confirm exactly what the mask covers?
Press Highlight in the viewer's upper left: gray is protected, normal display is the adjustment area; press again to turn it off.
The window won't drag past the frame edge?
Zoom the viewer out first (scroll wheel or Command-minus/Ctrl-minus), then drag the control points beyond the frame.
The window outline disappeared — did I lose it?
No. Click Overlay in the viewer's lower-left corner and choose Power Window; switching to another palette hides the outline too, but the window is still there.
The shape is too complex to draw with a window?
Two options: switch to the Curve pen for a freehand outline, or select by color with the qualifier (see Qualifier) and add a window on top.
