曲线Curves

调色 · Color

曲线是调色页里用曲线图调整亮度与色彩的工具,横轴是输入亮度,纵轴是输出亮度。

  • 把曲线向上拉,对应区域变亮;向下拉变暗;把曲线弯成 S 形可以增强对比度。
  • 除了亮度曲线,还有「色相 vs 色相」「色相 vs 饱和度」等曲线,做精准的局部色彩调整。
  • 曲线可以在多个节点上分别使用,把不同调整分开管理。

Curves is the Color page tool that adjusts brightness and color with a graph — horizontal axis is input, vertical axis is output.

  • Pull a curve up to brighten that range, down to darken; an S-curve boosts contrast.
  • Beyond the luminance curve there are curves like Hue vs Hue and Hue vs Sat for precise selective color work.
  • Curves can live on separate nodes, keeping each adjustment manageable.
