学习目标LEARNING OBJECTIVES

学完你能按"定黑白场 → 判偏色 → 加互补色 → 示波器验证"的固定流程，把一个偏色镜头校正回中性。

概念说明CONCEPTS

互补色校正（Complementary Color Correction）是把互补色原理落成固定流程的去偏色方法：先定明暗，再判偏色，朝互补方向轻拖，最后让示波器确认。原理见 互补色平衡，这里只讲怎么落地。

  • 先明暗后颜色：先用 Master Wheel 卡好黑场白场——曝光不对时，人眼判偏色一定不准。
  • 一次只对一个区：偏色常只待在某个亮度区（比如只有高光偏蓝）；用对应区的色轮，别动全局 Offset。
  • 示波器说了算：Parade 三通道顶端对齐 = 白平衡到位，底端对齐 = 黑场中性。眼睛几分钟就会"适应"偏色，波形不会。
  • 前后对比收尾：Shift-D 切换前后，确认结果是"更中性"，而不是"换了个方向偏"。

操作步骤STEPS

  1. 选中偏色片段，点右下角 Scopes 打开示波器并切到 Parade
  2. 用 Lift 和 Gain 的 Master Wheel 卡好黑场与白场先卡黑白场
  3. 观察 Parade：哪个通道的顶端（或底端）偏离另两路，就判定该亮度区偏这个色
  4. 在对应亮度区的色轮上，朝偏色的互补方向轻拖指示点，边拖边看三通道对齐朝互补方向轻拖并看 Parade
  5. 按 Shift-D 对比前后，满意后进入下一个镜头

练习PRACTICE

  1. 选一段只有高光偏蓝的素材，只用 Gain 色轮把高光拉回中性（Parade 顶端对齐）。
  2. 选一段整体偏暖的素材走完整套五步流程，用 Shift-D 向同学展示前后对比。

常见问题FAQ

整个画面都偏和只有高光偏，处理一样吗？

不一样。整体偏用 Offset；只有某个亮度区偏，就用对应区的色轮——动 Offset 会把没偏的区域一起带跑。

拖到什么程度算"到位"？

Parade 三通道顶端对齐、画面里中性物体不显色，即到位。宁欠勿过——拖过头就是反向偏色。

眼睛和示波器结论不一致时信谁？

信示波器。人眼会快速"适应"偏色，显示器本身也可能不准；以 Parade 三通道对齐为准。

Learning Objectives学习目标

After this card you can follow a fixed routine — set black/white points → judge the cast → add the complementary color → verify on scopes — to bring a tinted shot back to neutral.

Concepts概念说明

Complementary Color Correction turns the complementary principle into a repeatable procedure: brightness first, then judge the cast, nudge toward the opposite color, and let the scopes confirm. For the principle itself see Complementary Color Balance; this card is about putting it to work.

  • Brightness before color: set the black and white points with the Master Wheels first — with wrong exposure, your eyes will misjudge the cast every time.
  • One zone at a time: a cast often lives in a single brightness zone (say, only the highlights lean blue); use that zone's wheel instead of the global Offset.
  • Scopes have the final say: Parade channel tops aligned = white balance achieved; bottoms aligned = neutral blacks. Eyes adapt to a cast within minutes; the trace doesn't.
  • Finish with a before/after: toggle Shift-D and confirm the result is "more neutral", not "tinted the other way".

Steps操作步骤

  1. Select the tinted clip, open Scopes from the lower-right toolbar and switch to Parade
  2. Set the black and white points with the Lift and Gain Master WheelsSetting black and white points first
  3. Read Parade: whichever channel's top (or bottom) drifts from the other two marks the zone carrying that cast
  4. On that zone's wheel, nudge the indicator toward the complementary color, watching the three channels line up as you dragNudging toward the complement while watching Parade
  5. Press Shift-D to compare before and after, then move on to the next shot

Practice练习

  1. Take a clip whose highlights alone lean blue and neutralize them using only the Gain wheel (Parade tops aligned).
  2. Take a warm-tinted clip through the full five-step routine and demo the before/after to a classmate with Shift-D.

FAQ常见问题

Is an overall cast handled the same as a highlights-only cast?

No. An overall cast calls for Offset; a zone-specific cast calls for that zone's wheel — moving Offset would drag the clean zones along with it.

How far do I drag before it's "done"?

When the Parade channel tops align and neutral objects show no tint. Better slightly under than over — overshooting is just the reverse cast.

My eyes and the scopes disagree — which do I trust?

Trust the scopes. Eyes adapt to a cast quickly, and the monitor itself may be off; aligned Parade channels are the ground truth.
