Blend Modes

BLEND MODE EFFECT PRODUCED
Normal Pixels of current layer blend with lower layers only by adjusting opacity.
Darken Pixels of current layer that are darker than lower layers are applied, while the lighter pixels disappear.
Lighten The lighter of the blend and base colors is displayed.
Hue# Applies hue of selected layer to underlying layers.
Saturation# Applies saturation of selected layer to underlying layers.
Color# Applies hue and saturation of selected layer to underlying layers, the luminance is not affected.
Luminance# Applies luminance values of selected layer to underlying layers, color is not affected.
Multiply* Combines the color of the selected layer with underlying layers to produce a darker color (Black = black and White = no change).
Screen* Lightens underlying color by multiplying the inverse of the blend and base colors, resulting color is the same or a lightened version of the base color.
Dissolve Randomly replaces the colors of some pixels on the selected layer with those of the lower layers to create a speckled effect. The number of pixels replaced depends on the opacity (more replacement with decreased opacity).
Overlay Combines two previous blend modes showing patterns or colors of the upper layer while preserving the shadows and highlights of the lower layer (If underlying layer color channel value is less than half maximum, the Multiply blend mode is used, and if it is greater or equal to half the Screen blend mode is used).
Hard Light Combines two previous blend modes to add highlights or shadows (If the selected layer's color channel value is less than 128 (half max.), the Multiply blend mode is used, and if it is greater or equal to 128, the Screen blend mode is used).
Soft Light Combines two previous blend modes to add soft highlights or shadows (If the selected layer's color channel value is less than half max, the Burn blend mode is used, and if it is greater or equal to half the max. the Dodge blend mode is used).
Difference* Subtracts the selected layer's color from the color of the lower layers (depending on which is lighter).
Dodge The lightness values of the colors in the blend mode lighten the colors of the lower layers, overall lightening the image (light colors produce most lightening and black has no effect).
Burn The lightness values of the colors of the blend layer reduce the lightness of the lower layers, overall darkening the image.
Exlusion* Creates an effect similar to, but softer than the Difference mode.
*Note: these modes produce the same effect no matter which layer is on top.
