Graphicxtras > Affinity Photo Tutorials > Affinity Photo Filters Tutorials

Learn how to use the Average Filter in Affinity Photo to create unique color effects, abstract artwork, photo enhancements, and creative blending techniques. This tutorial explains where to find the filter, how it works, and several practical ways to use it with layers, channels, selections, and macros. Please note that the filter also works the same in Affinity 3

Where Is the Average Filter in Affinity Photo?

The Average Filter can be found in Affinity Photo under the Blur category of the Filters menu.

1. Open the Filters menu.
2. Select Blur.
3. Choose Average.

What Does the Average Filter Do?

The Average Filter calculates the average color value of all pixels within an image, layer, or selected area and replaces the contents with a single solid color based on that calculation. Although simple in appearance, it can be used to create a wide range of artistic and design effects when combined with other Affinity Photo features.

Is There a Live Average Filter?

No. The Average Filter is currently available only through the Filters menu and is not provided as a Live Filter Layer in Affinity Photo.

Results and Effects of the Average Filter

The resulting color depends entirely on the image content. For example, if an image is predominantly blue, the Average Filter may produce a solid blue fill. While this may seem limited at first, the filter becomes much more powerful when combined with blending modes, opacity settings, masks, and layer effects.

Creative Blending Techniques

One of the most effective ways to use the Average Filter is with layer blending modes. After applying the filter, use the Fade command, adjust layer opacity, or experiment with different blend modes to combine the averaged color with the original image.

Another technique is to duplicate the image layer, apply the Average Filter to one of the layers, and blend it with the original image. This can create subtle color harmonies, abstract artwork, and striking graphic effects.

You can also use a duplicated image to create simple frame designs. Resize the top layer and apply the Average Filter to the layer beneath it, creating a color-coordinated border based on the original image.

Using the Average Filter with Channels

Applying the Filter to Individual Color Channels

The Average Filter can be applied to individual channels within the Channels panel. Select the Red channel and apply the filter either directly from the Blur menu or by using the Repeat command. You can then use blending modes and opacity adjustments to refine the result.

Repeat the process on the Green or Blue channels using different blending settings to generate unique color variations. When finished, restore the image to RGB mode using the control at the top of the Channels panel.

Using Selections with the Average Filter

The Average Filter can be applied to selected portions of an image rather than the entire layer. Create selections using the Freehand Selection Tool, Elliptical Marquee, or selection commands such as Tonal Selection.

After applying the filter to a selection, move or modify the selection and apply the filter again. Repeating this process across different areas of the image can produce interesting artistic effects and layered color patterns.

Painting Effects Using Selections

Because the filter averages only the colors within the selected area, smaller selections often retain more of the original image characteristics. By combining feathered selections, additive selections, and subtractive selections, you can create painterly effects that resemble brush strokes, patches of color, or abstract painted regions.

Repeating the process with different selection shapes and sizes can transform photographs into stylized artwork while maintaining a connection to the original image content.

Automating the Average Filter with Macros

The Average Filter can be recorded as part of an Affinity Photo Macro and saved to the Library for future use. This allows you to automate repetitive workflows involving selections, transformations, and filter applications.

By combining the Average Filter with multiple selections, gradients, adjustment layers, blur effects, and blending modes, you can build complex artistic workflows that generate painted, textured, or abstract image effects from photographs.

The resulting artwork can also be combined with displacement effects and additional layer treatments to create even more advanced designs and creative compositions.

Frequently Asked Questions (FAQ)

What is the Average Filter in Affinity Photo?

The Average Filter is a blur-based effect that calculates the average color of all pixels within an image, layer, or selected area and replaces them with a single solid color. It is commonly used for color analysis, design work, and creative image effects.

Where can I find the Average Filter in Affinity Photo?

The Average Filter is located under the Filters > Blur > Average menu command in Affinity Photo.

Can I use the Average Filter on a selection?

Yes. The filter works on active selections as well as entire layers. Applying the filter to a selection averages only the colors within the selected area, making it useful for creating artistic and painterly effects.

Is the Average Filter available as a Live Filter Layer?

No. At the time of writing, the Average Filter is only available as a standard filter command and cannot be applied as a non-destructive Live Filter Layer.

Can I use the Average Filter with layer blending modes?

Yes. Combining the Average Filter with blending modes such as Overlay, Soft Light, Multiply, Screen, and Color can produce a wide range of creative effects and color harmonization techniques.

Can the Average Filter be used for graphic design projects?

Absolutely. Designers often use the Average Filter to extract dominant colors from photographs, create matching backgrounds, generate color palettes, and produce abstract graphic elements for posters, web graphics, and marketing materials.

Can I apply the Average Filter to individual channels?

Yes. The filter can be applied to individual Red, Green, or Blue channels through the Channels panel. This can create unusual color effects and experimental image treatments.

Can the Average Filter be recorded in a macro?

Yes. The Average Filter can be recorded as part of an Affinity Photo Macro and saved to the Library, allowing the effect to be reused across multiple projects and images.

What creative effects can be created with the Average Filter?

The filter can be used to create abstract artwork, painted image effects, color-based backgrounds, decorative borders, texture foundations, displacement maps, and blended color overlays when combined with other Affinity Photo tools.

Does the Average Filter change the original image permanently?

When applied directly to a pixel layer, the filter permanently changes that layer. To preserve the original image, duplicate the layer before applying the filter or work on a copy of the document.
