The add noise filter in Affinity Photo can be found in the noise category in the filters menu. The tool only has two options 1. intensity and 2. type.


You can use the add noise filter multiple times or once in Affinity Photo as well as combine them with other filters.


  1. Filters

  2. Noise menu

  3. Add noise

  4. Uniform / gaussian

  5. Monochromatic

  6. Apply


The add noise filter like all the other filters in the application needs something to work with and you can use the add noise with all kinds of image. It can be used to add subtle noise to an image but it can also be used to add extreme noise to an image. There are two options, the intensity can be set to 100% though weirdly the intensity of the noise can be set to more than 100% but the result looks different. How ? You can use the interactive dragging across the screen and it does increase the value and the result is a lot more noise than the basic 100% setting which is really odd.


You can also set it to gaussian or normal, they are subtly different. You can also have monochromatic (grey) noise as well if you wish.


You can also apply the add noise filter more than once and that maybe useful if you want more and more noise than the filter supplies.


You can also use the ann noise filter on a duplicate layer and then use blending modes to combine the noise effect with the underlying image as well as use opacity. You can do much the same with the layer menu and fade command where you can use the blending modes and opacity to change the add noise effect.


The add noise filter effect can also be applied in different color channels and you can do that by displaying the channels panel (find it in the view menu and studio and channels). Select gthe red channel and then apply the add noise filter to that. You can then repeat with the green channel but apply it with a different intensity setting etc


Selections can also be used with the add noise filter and you can create all kinds of selections such as freehand ones as well as tonal etc and once you have your selection you can apply the add noise filter and the effect will only be added to that.


You can also use the add filter in combo with other filters such as deform where you can distort the noise in all kinds of ways. The deform can be repeated and repeated to stretch the noise in many different ways and you can then combine multiple layers of these add noise / deformed layers


You can also use the add noise with pattern layers.


The add noise filter is also available in the live filter layers command in the layer menu. You can add more than one add noise layer. You can vary the settings of the add noise and use blending modes and opacity between the effects. You can also live edit the add noise filter effect as it is a non destructive effect
