学完你能说出 Lift、Gamma、Gain 三个色轮各管哪个亮度区域，会用色轮配合 Master Wheel 修正曝光与偏色。

概念说明CONCEPTS

Lift、Gamma、Gain 三个色轮是一级调色的核心工具，按亮度区域分工——它们在调色页面左侧的 Primary Corrector（一级校色器）里，每个色轮下面配一条管明暗的 Master Wheel。

  • Lift 管暗部：阴影、头发、夜景；拖它的 Master Wheel 定黑场。
  • Gamma 管中间调：肤色和主体大多在这一区；定画面氛围，不动已定好的黑白点。
  • Gain 管亮部：高光、天空、灯光；拖它的 Master Wheel 定白场。
  • 范围故意重叠：动 Lift 中间调也会跟着走，过渡才自然——代价是三个轮要来回配合，不是一个拧到底。
  • 互补色去偏色：画面偏什么色，就往色轮正对面轻拖——偏蓝向黄、偏红向青、偏绿向品红；中心点挪几像素就能看到变化。

常用顺序：先 Lift 和 Gain 卡黑白场，再 Gamma 调中间调——它不动已定好的黑白点；Offset 整体平移，入门先不碰。

下面这组对比就是一次典型的黑白场 + 去偏色校正（拖动滑块查看）：

调色前
调色后
Lift / Gamma / Gain 各管哪一段？

Lift = 暗部（定黑场）· Gamma = 中间调（定氛围）· Gain = 亮部（定白场）。顺序：先 Lift/Gain 定黑白，再 Gamma 调感觉。

拖一拖下面的三个滑杆，直观感受每个轮管哪段：

操作步骤STEPS

  1. 在编辑页面选中要调色的片段，点底部导航栏的 Color 进入调色页面进入调色页面
  2. 点时间线里要调的镜头（橙色描边 = 选中），点右下角 Scopes 打开示波器并切到 Parade
  3. 向右拖 Gain 的 Master Wheel，让 Parade 波形顶部接近 1023 但不超越——超越 = 高光细节被裁掉拖 Master Wheel 定白场
  4. 向左拖 Lift 的 Master Wheel，让波形底部碰到 0——黑场到位，对比度立刻出来
  5. 仍有偏色，就在对应区域的色轮上往互补色方向轻拖，同时看 Parade 三通道顶端对齐
  6. 最后用 Gamma 调中间调的明暗与冷暖——黑白点不动，放心调
  7. 点 Viewer 右上角的 Bypass（或按 Shift-D）对比调色前后，看完再点一次恢复

练习PRACTICE

  1. 找一段发灰、对比度低的素材，只用 Lift 和 Gain 的 Master Wheel 把黑场、白场分别卡到 0 和 1023 附近，再用 Bypass 对比前后。
  2. 找一段偏色明显的素材，先猜该往哪个互补色方向拖，再动手验证；每动一个轮，留意另外两个亮度区域受到的牵连。

常见问题FAQ

三个色轮到底怎么分工，先动哪个？

先 Lift/Gain 定黑白场（技术校正），再 Gamma 调中间调（艺术创作）。Lift 管暗部、Gain 管亮部、Gamma 管中间调；Offset 先不碰。

我动了 Lift，为什么中间调也跟着变了？

正常现象。三个轮的亮度范围故意设计成重叠，过渡才自然；代价是牵一发动全身——调完 Lift，回头看看 Gamma 要不要补一点。

画面偏黄/偏蓝，怎么知道往哪边拖色轮？

用互补色原理：偏什么色就往正对面拖——偏黄向蓝、偏蓝向黄、偏红向青、偏绿向品红。拿不准就开着 Parade，把三通道顶端（或底端）拖对齐。

色轮拖乱了，怎么回到默认？

每个区域右上角都有 Reset 一键复位；双击参数标签名可单个回默认。调色是非破坏性的，大胆试。

Learning Objectives学习目标

After this card you can say which brightness range each of the Lift, Gamma and Gain wheels controls, and use a wheel together with its Master Wheel to fix exposure and color casts.

Concepts概念说明

The Lift, Gamma and Gain wheels are the heart of primary grading, each owning one brightness range — they live in the Primary Corrector on the left of the Color page, and every wheel has a Master Wheel beneath it for brightness.

  • Lift drives the shadows: dark areas, hair, night scenes; its Master Wheel sets the black point.
  • Gamma drives the midtones: skin and most of your subject live here; it shapes the mood without touching the points you already set.
  • Gain drives the highlights: skies, lamps, bright edges; its Master Wheel sets the white point.
  • The ranges overlap on purpose: moving Lift nudges the midtones too, which keeps transitions smooth — the price is that the wheels work as a team, so expect to go back and forth.
  • Kill casts with complementary colors: whatever tint you see, nudge toward the color opposite it on the wheel — blue cast toward yellow, red toward cyan, green toward magenta; a few pixels is already visible.

A reliable routine: set the black and white points with Lift and Gain first, then shape the mood with Gamma — it leaves your points untouched; Offset shifts everything at once and can wait.

The pair below shows a typical black/white-point plus de-cast correction (drag the slider):

Before grading
After grading
Which range does each wheel drive?

Lift = shadows (sets the black point) · Gamma = midtones (sets the mood) · Gain = highlights (sets the white point). Order: black & white first (Lift/Gain), then feel (Gamma).

Drag the three sliders below and feel which range each wheel owns:

Steps操作步骤

  1. On the Edit page, select the clip you want to grade and click Color in the bottom navigation barEntering the Color page
  2. Click the shot in the timeline (orange outline = selected), open Scopes from the lower-right toolbar and switch to Parade
  3. Drag Gain's Master Wheel to the right until the Parade trace tops approach 1023 without crossing — crossing means clipped highlightsSetting the white point with the Master Wheel
  4. Drag Lift's Master Wheel to the left until the trace bottoms touch 0 — black point set, contrast snaps in
  5. Still seeing a cast? Nudge the matching region's wheel toward the complementary color while watching the Parade channel tops line up
  6. Finish with Gamma to set midtone brightness and warmth — your black and white points stay put
  7. Click Bypass at the viewer's upper right (or press Shift-D) to compare before and after, then toggle it back

Practice练习

  1. Take a flat, low-contrast clip and, using only the Lift and Gain Master Wheels, park the black and white points near 0 and 1023, then compare with Bypass.
  2. Take a clip with an obvious cast: guess the complementary direction before touching the wheel, then verify — and after each move, watch what happened to the other two brightness ranges.

FAQ常见问题

How do the three wheels split the work, and which do I touch first?

Lift and Gain first to set the black and white points (technical correction), then Gamma for the midtone mood (creative work). Lift = shadows, Gain = highlights, Gamma = midtones; leave Offset alone for now.

I moved Lift — why did the midtones change too?

That's by design. The three ranges overlap so transitions stay smooth; the trade-off is that every wheel pulls on its neighbors — after adjusting Lift, check whether Gamma needs a small compensating move.

The image looks yellow/blue — how do I know which way to drag?

Use complementary colors: drag toward the color opposite the cast — yellow cast toward blue, blue toward yellow, red toward cyan, green toward magenta. If unsure, open Parade and level the channel tops (or bottoms).

I dragged too far — how do I get back to default?

Every region has a Reset button in its upper-right corner, and double-clicking a parameter label resets that value. Grading is non-destructive, so experiment freely.
