Blend modes are one of those features where people either know them cold or just randomly click through the dropdown hoping something looks good. Let’s fix that.

Photoshop’s blend modes control how a layer interacts with layers below it. There are 27 of them, but they fall into logical groups, and once you understand the groups, the individual modes make sense.

Group 1: Normal

Normal — No blending. The top layer covers the bottom layer completely (at 100% opacity).

Dissolve — Replaces pixels randomly based on opacity. Creates a grainy, speckled effect. Honestly, I’ve used this maybe twice in 15 years.

Group 2: Darken

These modes only keep pixels that are darker than what’s below. Light areas disappear.

Darken — Compares each channel and keeps the darker value. Useful for compositing dark elements onto lighter backgrounds.

Multiply — Multiplies the pixel values together. Everything gets darker. White disappears completely. This is the go-to for adding shadows, darkening skies, and blending textures. If you learn one blend mode beyond Normal, make it Multiply.

Color Burn — Aggressive darkening with increased contrast. Great for moody, dramatic effects but easy to overdo.

Linear Burn — Similar to Multiply but darker. Useful for deep shadow effects.

Group 3: Lighten

The opposite of the Darken group. Only lighter pixels survive.

Lighten — Keeps the lighter value from each channel comparison.

Screen — The inverse of Multiply. Everything gets lighter. Black disappears completely. Perfect for brightening images, adding light effects, and compositing things like fire, lightning, or lens flares onto dark backgrounds.

Color Dodge — Aggressive lightening with blown highlights. Creates a bleached, overexposed look at high opacity.

Linear Dodge (Add) — Pure additive lightening. Useful for light effects.

Group 4: Contrast

These modes darken dark areas and lighten light areas simultaneously, increasing contrast. Neutral gray (50%) becomes invisible.

Overlay — The most popular contrast blend mode. Boosts contrast without blowing things out too much. Photographers love this for adding texture overlays — set a texture layer to Overlay and the 50% gray areas vanish while the texture detail enhances the image beneath.

Soft Light — A gentler version of Overlay. Subtle contrast boost. My personal favorite for dodging and burning: create a 50% gray layer set to Soft Light, then paint with white to lighten and black to darken.

Hard Light — Like Overlay but more aggressive. Good for bold, punchy effects.

Vivid Light, Linear Light, Pin Light, Hard Mix — Increasingly extreme contrast modes. Rarely used in photography, more common in graphic design and glitch art.

Group 5: Inversion

Difference — Shows the difference between layers. Identical areas become black. Useful for aligning layers — when you see all black, they’re perfectly aligned.

Exclusion — Similar to Difference but lower contrast. Can create interesting color effects.

Group 6: Component

These modes blend specific color properties: hue, saturation, color, or luminosity.

Hue — Applies the hue of the blend layer with the saturation and luminosity of the base.

Saturation — Applies the saturation of the blend layer only.

Color — Applies hue and saturation from the blend layer, keeping the luminosity of the base. This is the go-to for colorizing black and white photos or changing the color of an object naturally.

Luminosity — Applies only the brightness values from the blend layer. Use this when you want an adjustment to affect brightness without shifting colors — change a Curves layer’s blend mode to Luminosity to prevent color saturation changes.

The Ones That Actually Matter

For 90% of photography work, you need five blend modes:

  1. Multiply — Darken things
  2. Screen — Lighten things
  3. Overlay/Soft Light — Add contrast and texture
  4. Color — Change colors naturally
  5. Luminosity — Brightness adjustments without color shifts

Start with those five. Experiment with the others when you need something specific. And remember — you can always reduce a blend mode’s intensity by lowering the layer opacity. Multiply at 30% is a gentle darken. Screen at 20% is a subtle lift.

Cycle through blend modes quickly by selecting the Move tool (V) and pressing Shift + Plus/Minus. It’s the fastest way to preview how each mode affects your image.
