Adding noise to a colour in a simple way

[Ingolf]

Almost unusable from MP4 compression - but this is how I add noise to steps in a gradient in Affinity:

Horrible video

A bit of blur after can really make the grain look better.

With some easy and quick access to noise from a color selector and different types of grain, it would be fantastic.

Please note that adding it to only some gradient steps is vital; it is normal to add grain to the shadow/darker area of the gradient.

There is grainspiration out there

@PatrickM It is possible, a bit more steps than AD:
Open the Panels -> Effects -> Image Effects panel and add the Pixelate -> White Noise effect.

Click on the arrow next to the effect name to adjust effect options:

This is plain white noise. There is also a selection of procedural noise types (Perlin, Musgrave, Turbulence, etc) using the Generate -> Noise filter.

I will investigate if other noise types (random, but not white) are feasible.

@vectoradmin Thanks again. I may have found a bug: I could not disable the effect by clicking on the icon.

@vectoradmin another point I don't understand: I would like to mask the effect of the noise/grain on one side of the object and I try to use the gradient mask but all the noise disappears. What am I doing wrong? And how do I edit the mask after creating it?
thanks

@PatrickM I can disable (hide) the effect here on the Mac by clicking the 'eye' button.

But the gradient used as mask for the effect doesn't work in this case. It was working, IIRC. Looks like a bug.

You can edit the gradient used for masking the noise effect by selecting it again from the Opacity menu.

Tried (both on Windows and on Mac) but could not replicate this issue.

@b77 There seems to a bug (or more) here. This one can be replicated on Windows.

Nevertheless, the mask is edited by selecting "Gradient" again from the drop down.

Whilst looking at the noise image effect, I have a small observation: When the value of angle and offset are increased, the value no longer displays correctly. In this screenshot the angle should show a three digit number.

It looks like the Angle value is clipped, and needs a larger field.

@vectoradmin no way to hide the effect on my side. When I click elsewhere and then select the object, the effect is well enable. Do I send you the file by email?

@PatrickM Please send me the file by email.

@vectoradmin Ok, I found the issue. It's fine when the panel is free:

but the issue is there when the panel is docked:
