Photoshop 混合模式科学与数学公式：暗化组（暗化、正片叠底、颜色燃烧、线性燃烧）、亮化组（亮化、屏幕、颜色 dodge、线性 dodge）、对比度组（叠加、柔光、强光、鲜艳光）、组件组（色相、饱和度、颜色、亮度）。快速参考：去除黑白背景、添加光晕/阴影、纹理叠加、色彩调色、高通锐化。

Quick reference for removing black/white backgrounds, adding glow/shadow, texture overlay, color tinting, high-pass sharpen."

§2 BLEND MODE SCIENCE

Every blend mode is a math formula combining the current layer (top) with layers below (bottom).

DARKEN GROUP — Result is always darker or same

ModeFormulaUse For
DARKENmin(top, bottom)Composite dark elements, remove white backgrounds
MULTIPLYtop x bottom / 255Shadows, dark overlays, multiply textures. Black stays black, white disappears
COLOR_BURN1 - (1-bottom)/topIntense dark contrast, dramatic shadows
LINEAR_BURNtop + bottom - 255Darker than Multiply, harsh dark blending

LIGHTEN GROUP — Result is always lighter or same

ModeFormulaUse For
LIGHTENmax(top, bottom)Composite light elements, remove black backgrounds
SCREEN1 - (1-top)(1-bottom)Glow effects, light leaks, neon text. White stays white, black disappears
COLOR_DODGEbottom / (1-top)Intense highlights, glowing edges
LINEAR_DODGEtop + bottomBrightest additive blend, lens flares

CONTRAST GROUP — Darken darks, lighten lights

ModeFormulaUse For
OVERLAYMultiply if bottom<128, Screen if >128Most versatile. Texture overlay, high-pass sharpen, color grading
SOFT_LIGHTGentle OverlaySubtle color tinting, gentle light/shadow. Best for color grading
HARD_LIGHTMultiply if top<128, Screen if >128Like Overlay but keyed to TOP layer
VIVID_LIGHTColor Burn/Dodge comboUse batchplay for this blend mode

COMPONENT GROUP — Blend specific color properties

ModeFormulaUse For
HUEHue from top, Sat+Lum from bottomChange colors without affecting light/shadow
SATURATIONSat from top, Hue+Lum from bottomDesaturate/saturate specific areas
COLORHue+Sat from top, Lum from bottomColorize. Tinting photos, hand-coloring B&W
LUMINOSITYLum from top, Hue+Sat from bottomApply brightness changes without color shifts

QUICK REFERENCE

code
Remove black background  → SCREEN
Remove white background  → MULTIPLY
Add glow/light           → SCREEN or LINEAR_DODGE
Add shadow/darkness      → MULTIPLY
Texture overlay          → OVERLAY or SOFT_LIGHT
Color tinting            → SOFT_LIGHT or COLOR
High-pass sharpen        → OVERLAY
Color grading            → SOFT_LIGHT
