: How to apply grain texture effect in GIMP I am trying to follow https://medium.com/google-design/salt-pepper-the-art-of-illustrating-texture-c962dc67cc35 to add material design effect to my project in

@Kimberly620

Put your shape layer inside a layer group (Layer>New Layer Group; drag the layer onto the group in the layers list). This group will hold your shape and any textures we add.





Make a new transparent layer in the layer group on top of your shape layer. This is the layer we're going to put the texture on.





Set the layer Mode from "Normal" to "Soft Light".
With the new transparent layer selected, draw the gradient you want using the gradient tool (click and drag from the start to the end of where you want your gradient to be). I'll do a simple black/white gradient. Now we have a gradient, but no texture!





Run Filters>Noise>Spread to randomly move the pixels of our gradient around. Set the amount to something large (like 100) for more effect.





If you want slightly more realistic grain, use Filters>Blur>Gaussian Blur (1-3px) then Filters>Enhance>Sharpen (set to 50+%). This keeps the grain from being just 1px noise.




You can extend this even more by adding multiple grain layers, different blend modes, or adding grain from a texture image.

Hope that helps!

Add a layer, fill with Filters>Noise>HSV Noise, then either:


You use one of several modes (darken only, multiply, divide, overlay, soft light... ) and adjust opacity
You use the noise layer as a bump map, using Filters>Map>Bump map, or as part of a more complex process that uses Filters>Light and shadow>Lighting effects
