学习目标LEARNING OBJECTIVES

学完你能说清一级调色（Primary Color Correction）要解决什么问题、按什么顺序动手，并完成一个镜头从评估到定调的完整第一遍校正。

概念说明CONCEPTS

一级调色（Primary Color Correction）是对整条画面做的全局色彩与对比调整——不调局部、不挑对象，目标是先把素材"校正正常"，再谈风格好看。

  • 先校正后创作：第一遍解决曝光、对比度、白平衡这些技术问题（Correction）；风格化的"好看"（Grading）放到后面。
  • 工具按区分工：色轮管分区明暗与偏色（见 一级调色轮），曲线管精细对比（见 自定义曲线调色），色温管整体冷暖——都在左侧一级校色器（Primary Corrector）里。
  • 眼睛加示波器：眼睛会累、显示器会骗人，曝光和偏色让示波器作证（见 视频示波器），感觉留给你拍板。
  • 一致性是硬指标：同一场景的镜头要看起来在同一时间、同一地点拍摄——一级调色把"各自为政"的素材统一成一场戏。
  • 一个调整一个节点：第一遍校正在节点 01 上做，后续对比、色温各占新节点（见 理解节点）。

操作步骤STEPS

  1. 在 Color 页面选中镜头，点 Scopes 打开 Parade 先评估：波形挤在哪、三通道齐不齐用 Parade 评估素材
  2. 用 Lift / Gain 的 Master Wheel 卡黑白场：波形底部贴 0、顶部接近 1023（手法见 一级调色轮）卡黑白场
  3. 哪段偏色就在哪个色轮上往互补色方向轻拖，同时看 Parade 三通道顶端、底端对齐
  4. 用 Gamma 定中间调的明暗与冷暖——肤色和主体的"感觉"在这里拍板
  5. 按 Shift-D（或点 Bypass）对比前后；满意后 Option-S/Alt-S 加新节点，再做对比度或色温等下一步

练习PRACTICE

  1. 找一段发灰的素材，按"评估 → 黑白场 → 去偏色 → 中间调"走一遍，每步只用一句话记录你做了什么。
  2. 找同一场景的两段素材，把第二段调到和第一段像"同一场戏"，用 Shift-D 轮流对比确认。

常见问题FAQ

一级调色和二级调色有什么区别？

一级调整条画面的全局（曝光、对比、白平衡）；二级针对画面里特定区域或颜色（第 5 课的限定器、Power Window）。顺序永远是先一级后二级。

每个镜头都要从零调一遍吗？

思路相同，但不必从零。同场景镜头调好一个后可以复用节点树再微调，目标是整组镜头一致（见 镜头匹配）。

手机或普通相机拍的素材也需要一级调色吗？

需要。只要画面发灰、偏色、曝光不准，就值得做一遍；手机直出素材往往只需轻调，log 素材则必须先校正（见 色彩管理）。

先剪辑还是先调色？

正式项目一般在画面定剪后再细调，避免剪掉的镜头白调。本课程直接进 Color 页面练习，顺序问题不影响学习。

After this card you can explain what Primary Color Correction is for and in what order to approach it, and complete a full first-pass correction on a shot from assessment to final look.

Concepts概念说明

Primary Color Correction is the global adjustment of color and contrast across the entire frame — no local fixes, no singling out objects. The goal is to make footage "correct" first, and only then make it pretty.

  • Correct first, create later: pass one fixes technical issues — exposure, contrast, white balance (Correction); the stylish "look" (Grading) comes after.
  • Tools split the work: wheels handle per-zone brightness and casts (see Primary Color Wheels), curves handle fine contrast (see Custom Curves), temperature handles overall warmth — all inside the Primary Corrector on the left.
  • Eyes plus scopes: eyes get tired and displays lie — let scopes testify about exposure and casts (see Video Scopes), and save your taste for the final call.
  • Consistency is the hard metric: shots in one scene must look filmed at the same time and place — primary grading unifies unruly footage into one scene.
  • One adjustment per node: the first pass happens on node 01; contrast, tint and friends each get their own new node (see Understanding Nodes).

Steps操作步骤

  1. On the Color page, select a shot and click Scopes to open the Parade — assess first: where do traces bunch up, are channels levelAssessing footage with the Parade
  2. Set black and white points with the Lift and Gain Master Wheels: trace bottoms touch 0, tops approach 1023 (see Primary Color Wheels)Setting black and white points
  3. Wherever a cast sits, nudge that zone's wheel toward the complementary color while leveling the Parade channel tops and bottoms
  4. Use Gamma to set midtone brightness and warmth — the "feel" of skin and subject gets decided here
  5. Press Shift-D (or click Bypass) to compare; when happy, press Option-S/Alt-S for a new node and move on to contrast or tint

Practice练习

  1. Take a flat-looking clip and walk through "assess → black/white points → de-cast → midtones", writing one sentence about what you did at each step.
  2. Take two shots from the same scene and grade the second to feel like "the same scene" as the first — verify by toggling Shift-D on both.

FAQ常见问题

What's the difference between primary and secondary correction?

Primary adjusts the whole frame (exposure, contrast, white balance); secondary targets a specific area or color in the frame (Lesson 5's qualifiers and Power Windows). The order is always primary first.

Do I have to grade every shot from scratch?

Same thinking, not the same starting point. Once one shot in a scene is graded, you can reuse its node tree and fine-tune — the goal is a consistent set (see Shot Matching).

Does phone or consumer-camera footage need primary correction too?

Yes. If the image looks flat, tinted or badly exposed, it deserves a pass; phone footage usually needs only a light touch, while log footage must be normalized first (see Color Management).

Should I edit first or grade first?

In real projects, fine grading usually waits for picture lock so you don't grade shots that get cut. In this course you jump straight into the Color page — order doesn't affect your learning here.
