学习目标LEARNING OBJECTIVES

学完你能说出 HDR 色轮（HDR Wheels）六个分区各管哪段亮度，会用每区的 Highlight 预览按钮和独立 Saturation/Exposure 滑块做精细分区调整。

概念说明CONCEPTS

HDR 色轮（HDR Wheels）把亮度范围切成六个区——Black、Dark、Shadow、Light、Highlight、Specular——比 Lift/Gamma/Gain 的三区分得细得多，为高动态范围素材的精细调色而生，调普通 SDR 素材同样好用。

  • 六区分两组：面板一次显示三个轮，点顶部圆形图标在暗部组（Black/Dark/Shadow）和亮部组（Light/Highlight/Specular）之间切换。
  • Global 轮常驻：最左侧的 Global 轮始终显示，作用类似 Offset、整片平移；想把它的位置让给别的区，可在面板选项里改设置。
  • 每区独立饱和与曝光：每个区自带 Saturation 和 Exposure 滑块——只给某一亮度区加艳或压暗；标准三轮做不到，得借助二级工具。
  • Highlight 按钮预览辖区：按住某区的 Highlight 按钮，Viewer 里不受该区影响的区域变灰——这个轮到底动哪里，一眼看清。
  • 区间有过渡、宽窄可调：六区之间像标准轮一样带滚降过渡，但每个区的覆盖宽窄可以调整，精度由你定。

操作步骤STEPS

  1. 在 Color 页面选中镜头，点左侧调色面板顶部的 HDR Wheels 图标切入该面板切到 HDR Wheels 面板
  2. 点顶部圆形图标，把显示的三个轮切到要调的区组：暗部组 Black/Dark/Shadow 或亮部组 Light/Highlight/Specular
  3. 按住某个区的 Highlight 按钮，在 Viewer 里确认它的辖区（变灰 = 不受影响）用 Highlight 按钮预览辖区
  4. 拖该区色轮中心上色，拖 Exposure 管明暗、Saturation 管浓淡——只动这个亮度区
  5. 按 Shift-D 对比前后；每个区右上角有 Reset 可单独复位

练习PRACTICE

动手任务

  1. 找一段天空发白的高动态范围素材，用 Highlight 区加蓝、Saturation 微加艳，再用 Specular 区给最亮处补一点暖色，Shift-D 对比前后。
  2. 按住每个区的 Highlight 按钮轮流看一遍，说出六个区在这段素材上各管画面哪部分。

做完任务后逐条自查，全部能打勾才算过。

常见问题FAQ

SDR 素材能用 HDR 色轮吗？

能。六区只是更细的亮度划分，对任何素材都有效；只是高动态范围素材的高光层次多，更能体现它的价值。

一级三轮、Log 轮、HDR 轮怎么选？

按"先粗后细"上场：一级三轮做大平衡（见 一级调色轮），Log 轮做窄区精修（见 对数色轮），HDR 轮把高光和暗部内部再分层，做最细的分区调整。

Global 轮和 Offset 轮是一回事吗？

作用类似：整片平移、不分区。Global 轮默认常驻面板最左侧；想把它的位置让给其他区，可在面板选项中更改。

调乱了怎么恢复？

每个区右上角有 Reset 单独复位。调色是非破坏性的，随时 Shift-D 对比、随时推倒重来。

Learning Objectives学习目标

After this card you can say which brightness range each of the six HDR Wheels zones controls, and use each zone's Highlight preview button plus its dedicated Saturation/Exposure sliders for precise zone grading.

Concepts概念说明

The HDR Wheels split the brightness range into six zones — Black, Dark, Shadow, Light, Highlight and Specular — far finer than the three Lift/Gamma/Gain zones. They were built for high-dynamic-range footage, and they work just as well on ordinary SDR clips.

  • Six zones in two banks: the panel shows three wheels at a time; click the circular icons along the top to switch between the dark bank (Black/Dark/Shadow) and the bright bank (Light/Highlight/Specular).
  • The Global wheel stays put: the leftmost Global wheel is always visible and behaves like Offset, shifting the whole frame; if you'd rather use its slot for another zone, change it in the panel options.
  • Per-zone saturation and exposure: every zone carries its own Saturation and Exposure sliders — saturate or darken one brightness range only, something the standard wheels can't do without secondary tools.
  • The Highlight button previews territory: press and hold a zone's Highlight button and every area it does NOT affect turns gray in the viewer — you see exactly what the wheel owns.
  • Soft transitions, adjustable widths: the six zones roll off into each other like the standard wheels, but each zone's coverage can be adjusted — you choose the precision.

Steps操作步骤

  1. On the Color page, select a shot and click the HDR Wheels icon at the top of the left grading panelSwitching to the HDR Wheels panel
  2. Click the circular icons along the top to show the bank you need: dark (Black/Dark/Shadow) or bright (Light/Highlight/Specular)
  3. Press and hold a zone's Highlight button to confirm its territory in the viewer (gray = not affected)Previewing a zone with the Highlight button
  4. Drag the zone's wheel center to tint it, Exposure for brightness, Saturation for vividness — only this brightness range moves
  5. Press Shift-D to compare; every zone has its own Reset in the upper right

Practice练习

Hands-on task

  1. Take a washed-out-sky HDR clip: add blue with the Highlight zone, nudge Saturation up slightly, then add a touch of warmth to the brightest area with Specular — compare with Shift-D.
  2. Hold each zone's Highlight button in turn and say out loud which part of the frame each of the six zones owns in this shot.

Self-check

Work through the task, then tick every line; all checked means you own this card.

FAQ常见问题

Can I use the HDR Wheels on SDR footage?

Yes. The six zones are simply a finer brightness division and work on any footage; high-dynamic-range material just shows off their value most, with its layered highlights.

Primary wheels, Log wheels or HDR wheels — which when?

Coarse to fine: primary wheels for the overall balance (see Primary Color Wheels), Log wheels for narrow-zone refinement (see Log Color Wheels), HDR wheels to subdivide highlights and shadows further for the finest zone work.

Is the Global wheel the same as Offset?

Similar job: shifting the whole frame with no zones. Global stays docked at the panel's left by default; if you want its slot for another zone, change it in the panel options.

How do I recover when I've made a mess?

Every zone has its own Reset in the upper right. Grading is non-destructive — compare with Shift-D and start over whenever you like.
