学习目标LEARNING OBJECTIVES

学完你能分清技术 LUT 和创意 LUT，会把第三方 LUT 装进 Resolve，并按"先校正、后风格"的顺序套到节点上。

概念说明CONCEPTS

LUT（查找表，Look-Up Table）是把一组输入颜色值映射成另一组输出值的文件——它不"分析"画面，只是按表替换；套上去就是一套固定的色彩变换。

  • 两类 LUT 别混用：技术 LUT 做色彩空间转换（如 Log 转 Rec.709），创意 LUT 做风格化（胶片模拟、色调预设）；顺序是先转换、再风格。
  • LUT 是死的：一张表对应一种固定变换，不认画面内容——曝光不准的素材套上只会更难看。
  • 先校正后套用：在 LUT 之前的节点把曝光和白平衡调准，LUT 才能发挥它设计时的效果。
  • 独占一个节点：LUT 单独放一个节点，前后都留出调整余地，开关对比也方便。
  • 强度可以打折：降低节点的 Key Output Gain，相当于给 LUT 调"浓度"，不动文件本身。

操作步骤STEPS

  1. 打开 Project Settings → Color Management，点 Open LUT Folder
  2. 把 .cube 文件拷进该文件夹，回 Resolve 点 Update Lists 刷新列表LUT 文件夹与更新列表按钮
  3. 到调色页选中一个空节点，打开 LUTs 面板浏览缩略图
  4. 悬停在某个 LUT 上实时预览，双击或拖到节点上套用LUTs 面板悬停实时预览
  5. 在 LUT 节点之前的节点校正曝光和白平衡，之后微调，太重就降 Key Output Gain

练习PRACTICE

  1. 把一个 .cube 文件装进 LUT 文件夹并 Update Lists，在 LUTs 面板找到它并套到节点上。
  2. 同一段素材做对比：未校正直接套 LUT vs 先校正曝光再套，用 Command/Ctrl+D 开关节点看差别。

常见问题FAQ

导入的 LUT 怎么在列表里看不到？

拷进 Open LUT Folder 打开的文件夹后，要回设置里点 Update Lists 才刷新；文件必须是 .cube 等支持的格式。

套上 LUT 画面又黑又艳怎么办？

素材状态不符合这张 LUT 的预期。在前面的节点把曝光、对比度、白平衡调准，或换一个为该类素材设计的 LUT。

LUT 效果太重能淡一点吗？

能。选中 LUT 节点，把 Key Output Gain 从 1.0 往下调，就是给 LUT"减浓度"。

After this card you can tell technical LUTs from creative ones, install third-party LUTs into Resolve, and apply them in the right "correct first, then style" order.

Concepts概念说明

A LUT (Look-Up Table) is a file that maps one set of input color values to another set of output values — it doesn't "analyze" your image; it just replaces values by the table, applying one fixed color transform.

  • Two kinds, don't mix them up: technical LUTs convert color spaces (e.g. Log to Rec.709); creative LUTs stylize (film emulation, tone presets). Convert first, style second.
  • A LUT is fixed: one table, one transform — it knows nothing about your footage, so badly exposed shots only look worse under it.
  • Correct before you apply: fix exposure and white balance in nodes before the LUT, so it behaves the way it was designed to.
  • Give it its own node: the LUT sits alone on one node, leaving room to adjust before and after, and making A/B toggling easy.
  • Strength is adjustable: lower the node's Key Output Gain to thin the LUT like a "density" control, without touching the file.

Steps操作步骤

  1. Open Project Settings → Color Management and click Open LUT Folder
  2. Copy .cube files into that folder, then back in Resolve click Update ListsLUT 文件夹与更新列表按钮
  3. In the Color page, select an empty node and open the LUTs panel to browse thumbnails
  4. Hover over a LUT for a live preview, then double-click or drag it onto the nodeLUTs 面板悬停实时预览
  5. Correct exposure and white balance in nodes before the LUT, fine-tune after it, and lower Key Output Gain if it's too strong

Practice练习

  1. Install a .cube file into the LUT folder, click Update Lists, find it in the LUTs panel and apply it to a node.
  2. Compare on the same shot: LUT on uncorrected footage vs. after an exposure fix — toggle the node with Command/Ctrl+D to see the difference.

FAQ常见问题

My imported LUT doesn't show up — why?

After copying files into the folder opened by Open LUT Folder, you must click Update Lists to refresh; the files also need to be a supported format like .cube.

The LUT makes everything dark and oversaturated?

Your footage doesn't match what that LUT expects. Fix exposure, contrast and white balance in earlier nodes, or pick a LUT designed for that kind of footage.

Can I make a LUT less intense?

Yes. Select the LUT node and lower Key Output Gain below 1.0 — that's turning the LUT's "density" down.
