偏移Offset

偏移是一级校色轮之一，整体移动画面的亮度：向上拖整体变亮，向下拖整体变暗，同时也会整体偏向所拖的颜色。

• 与 Lift、Gamma、Gain 分别控制暗部、中间调、亮部不同，Offset 对整幅画面一视同仁。
• 在色轮中心拖动时，画面亮度整体平移，常用于快速提亮或压暗整段素材。
• 对波形的影响是整体上下移动，而不是压缩或拉伸。

Offset is one of the primary color wheels that shifts the whole image's brightness: drag up to brighten everything, down to darken everything, and toward a color to tint the entire image.

• Unlike Lift, Gamma, and Gain, which target shadows, midtones, and highlights separately, Offset treats the whole frame equally.
• Dragging from the center moves overall brightness — handy for quickly brightening or darkening a clip.
• On the waveform it shifts everything up or down, rather than compressing or stretching it.
