Layer blending

A layer's blend mode determines how the layer or object's pixels blend with the pixels on the layer beneath.

Blend Modes
Common blend modes: (A) Normal, (B) Multiply, (C) Screen, (D) Overlay, (E) Divide (F) Colour Burn.

Blend mode types

Affinity apps support an impressive selection of different blend modes. They are organised in their respective groups, which initially inform of the effect they add. They are as follows:

Normal

The default and starting mode for layers. It results in fully opaque pixels appearing above the underlying pixels. Use to completely cover the underlying layer's content.

Normal blend mode
DARKEN GROUP
Darken

Compares pixels of the active vs the underlying layer(s) and leaves darker pixels visible. Use to create dramatic, moody atmosphere.

Darken blend mode
Multiply

One of the most frequently used blend modes in the group. Each pixel of the active layer is multiplied with the pixels of the layer(s) below. Bright pixels are ignored while darker ones are intensified. This results in a darker overall output when compared to the Darken blend mode. Use to create darker outputs with increased contrast.

Multiply blend mode
Colour Burn

Results in more saturated mid-tones and reduced highlights by intensifying contrast and the underlying layer's colours. Use to exaggerate colours and create highly contrasting scenes.

Colour Burn blend mode
Linear Burn

Results in darker output than with Multiply blend mode, yet less saturated than Colour Burn. Lighter pixels of the active layer(s) are unaffected. This mode is ideal for rendering darker tones in the shadows and mid-tones.

Linear Burn blend mode
Darken Colour

Compares the colour values of the active and underlying layer(s) and only retains the darker ones. Use to accentuate the darker tones from both layers.

Darken Colour blend mode
LIGHTEN GROUP
Lighten

Results in only the brighter values being retained upon comparing the active and underlying layer(s). Use to add complimentary colour tint to images.

Lighten blend mode
Screen

Inverts colours of the underlaying layer(s) and multiplies it with those of the active layer: this results in generating smooth results. It is one of the most commonly used blend modes due to its soft rendering.

Screen blend mode
Colour Dodge

Increases the luminosity of the underlying layer(s) while reducing contrast between both the active and underlying layer(s). It results in a stronger effect than the one produced by Screen with saturated mid-tones and intense highlights. Use to accentuate colour and highlights.

Colour Dodge blend mode
Add

Results in added colour information to both the active and underlying layer(s) and increases overall brightness while not affecting the black tones. Use to reveal brighter tones in images.

Add blend mode
Lighter Colour

Rather than looking at individual colour, this mode uses perceived luminosity from all colour channels to determine which pixel is lighter. It acts as an inverted luminosity mask. Use for faded looks and smooth rendition of highlights in outputs.

Lighter Colour blend mode
CONTRAST GROUP
Overlay

Compares the active and underlying layer(s) and shifts to darker mid-tones if the colours are lighter than 50% grey. Results in darkening the darker pixels of the images and lightening the lighter ones. Use to enhance contrast and saturation.

Overlay blend mode
Soft Light

Results in a more diffused effect from comparing luminance and colour values between the active and underlying layer(s). Use for subtle blending and faded looks.

Soft Light blend mode
Hard Light

Results in a dramatic, high-contrast effect. The top layer is used to determine the calculation required for the evaluation of pixels. Its effect can be observed as the opposite of the Overlay blend mode. Use to enhance colour contrast and reduce opacity, as required, to achieve best results.

Hard Light blend mode
Vivid Light

This blend mode applies the effect of the Colour Burn or Colour Dodge blend mode based on the comparison of RBG channels in the active (top) layer and underlying layer(s). Colour Dodge is applied when the top layer image's values are lighter than mid-grey; Colour Burn is applied when the top layer image's values are darker than mid-grey. Mid-grey serves as a neutral colour, so any pixels with a grey value of 50% are not affected.

Results in increased contrast and highly saturated colours. Use to enhance contrast and colour intensity, though best results are achieved with reduced opacity.

Vivid Light blend mode
Linear Light

Brighter pixels receive lighter treatment while darker ones get darkened. Results in a stronger contrast in the mid-tones. Use to create a dramatic, enhanced effect.

Lineal Light blend mode
Pin Light

Results can be compared to a mix of those achieved with the Darken and Lighten blend modes. This blend mode creates distinct boundaries between the dark and light regions. Use to achieve pronounced, yet somewhat faded look.

Pin Light blend mode
Hard Mix

Results in a highly-contrasting effect between pixels (modified by either 0 or 1). The effects can be attributed to the output often observed in comic books or posters where the increase in contrast accentuates colours. Use to posterise or to maximise colour contrast.

Hard Mix blend mode
INVERSION GROUP
Difference

Calculates the absolute difference between the active and underlying layer(s). When using this blend mode, similar values cancel each other out. Use to find errors in images.

Difference blend mode
Exclusion

Results in similar output to the above (Difference) mode, however with a softer effect. Use for soft blending of images consisting of similar luminance values.

Exclusion blend mode
Subtract

Subtracts the top layer's pixel values from the underlying layer, which results in lighter areas becoming brighter whereas the darker areas seeing little to no change. Use to remove or fade the active layer's colours and/or luminosity.

subtract blend mode
Divide

The underlying layers' pixel values are divided by those of the active layer, which usually results in brighter images. The effect of this blend mode is the opposite of the Subtract mode; darker colour values create brighter results while brighter colour values see little to no change. Use to simulate film negative look.

Divide blend mode
COMPONENT GROUP
Hue

Combine the hue of the active layer with that of the underlying layer(s). Use to exaggerate or create intense colours and to produce vivid, often surreal scenes.

Hue blend mode
Saturation

Similar to the Hue blend mode, however here Saturation is the replaced component. Depending on your images' saturation and colours, use this blend mode, as an alternative to the above, and to intensify and exaggerate colours.

Saturation blend mode
Colour

Combines the hue and saturation values of the active layer with the brightness of the underlying layer(s). Additionally, only the brightest colours of the underlying layer(s) are retained. Use to stylise images to produce scenes with intensified hue and saturation levels.

Colour blend mode
Luminosity

Combines the brightness values of the active layer with the brightness of the underlying layer(s). This blend mode's effect is the opposite of the Colour blend mode — it retains the hue and saturation of the underlying layer(s). Use to add detail and textures where colour information of the added image layer is less important.

Luminosity blend mode
AFFINITY GROUP
Average

Combines the colour and luminance values of the active and underlying layer(s) in producing a mean average. The result is similar to the one achieved by setting the active layer's Opacity to 50%. Use to simulate simple double-exposure images.

Average blend mode
Negation

Similar in effect to the Difference blend mode (Inversion group), which may be used as its alternative. Use to produce more contrasting and intense scenes; particularly powerful when working with selections and masking.

Negation blend mode
Reflect

Combines the effects of the Hard Light and Hard Mix blend modes (Contrast group) and produces images with preserved darker tones while enhancing the lighter ones. Use as an alternative to control image contrast; the method is particularly useful when combined with manipulating the source layer's graph to reduce highlights output via the Blend Ranges option.

Reflect blend mode
Glow

The opposite of the Reflect blend mode, which produces images with preserved lighter tones (while enhancing the darker ones). As above, use to manipulate contrast and combine it with the Blend Ranges to obtain best outcomes.

Glow blend mode
Contrast Negate

Inverts pixel values depending on those of the underlying layer's content versus the active layer. Use to create effects similar to those of a two-tone colour grade and posterisation.

Contrast Negate blend mode
Erase

Excludes pixels of the underlying layer. Use in combination with layer Opacity to produce faded and transparent outputs or to hide pixels from the layer(s) below the active one.

Erase blend mode
Erase blend mode set to shapes (from left) at 25%, 50% and 75% Opacity over the base image.

'Special 8' blend modes and fill opacity

When adjusting blend opacity, some blend modes (listed below) work best by adjusting Fill Opacity, rather than the layer's Opacity. The Fill Opacity option is available from the Layers panel’s Blend Options option. Fill opacity is essential when using Hard Mix blending in particular.

Layers panel Layer Options To change the blend mode of a layer:
  1. On the Layers panel, select a layer, then do one of the following:
    • Tap the current blend mode (next to the Opacity option).
    • Select Layer Options, then tap the current blend mode (below the Opacity option).
  2. Choose a blend mode from the pop-up menu.
