Diffuse Filter / Noise Effect for Affinity Photo Tutorial Beginner's Guide

By Andrew Buckle, Video Tutorial Creator / Designer

Updated : 2021

 

The diffuse filter for Affinity Photo can be found in the noise category of the filters menu. The diffuse filter can be used multiple times or once and can be combined in millions of ways with the other filters.

 

The diffuse filter can be used with images and type as well as with brush strokes and fonts designs.

 

The diffuse filter is found via noise category and is a powerful noise effect that can totally dissolve an image or just add a subtle noise to the edge of an image and much more.

 

You can repeat apply the diffuse noise filter either with the same setting or by changing the diffuse settings (there is only one) you can get a very different effect added. You can also combine the diffuse filter effect with others and if you wish you can record the various steps via the macro panel and replay it on other images.

 

You can also use the diffuse filter with the powerful fade command found in the layer menu, the fade allows you to blend the result with different blending modes such as difference, lighter color, overlay and more. You can also modify the opacity of the effect / original image

 

You can use the diffuse filter in Affinity Photo with layers, especially powerful if you reduce the size of the newly duplicated layer and then apply the effect. You can then take the result of that and distort it in 1000s of ways with the powerful mirror and deform filters.

 

You can use channels with the diffuse filter, just go to the channels panel found in the view menu and studio. You can then select the red channel and apply the diffuse to that with one set of settings and then go to the blue channel etc with a different set as well as combine with other filters such as deform or blur.

 

Selections are also super useful with the diffuse filter as you can apply the diffuse effect to a selected area created via the select menu or via the selection tools such as freehand or rectangle marquee. You can then move the selection and then apply a different diffuse filter effect on that.

 

The diffuse filter can also be used in combo with the powerful pattern layer from selection, so you can create some truly awesome diffuse patterns as well as again combine with other filters in the distort menu etc.

 

You can also use the diffuse filter with shapes, vector shapes that are created by the shape tools or perhaps shapes created with the pen tool and manipulated by the node tool.

 

Text can also be diffused as well.
