Hi all.

I'd like to be able to create a rough, even texture. The perfect examples are these:
http://data.markjardine.com/tumblr/img/bg_texture.png http://data.markjardine.com/tumblr/img/button_nav_right.png

The texture dominates the design style at: http://markjardine.com/

I know that style is a little trendy and all. But I still think it's a nice effect. I've been able to achieve it before, but I can't figure out how to do it again.

I can't quite get it with just HSV noise.

I've been playing with the noise generator: http://registry.gimp.org/node/13016

I can get kind of close with just gaussian noise, stdev set to 2.5. But my result seems a little blurry.

How would you guys create this effect ?

The background at http://data.markjardine.com/tumblr/img/bg_texture.png looks like it it could have been made following this tutorial http://gimp-tutorials.net/gimp-pattern#comment-4062

You can vary various things to get the effect you want, here is something that is perhaps a little coarse and dark compared to what you want http://members.pcug.org.au/~rcook/cf1.html

FWIW

I personally found nothing remarkable didn't like the examples you provided - I guess going to filters->noise->hurl, followed by colors->desaturate and colors->curves to fit the gray ranges to desired values should give you better results.

I am more for stuff likje this when talking concrete, though: http://www.pion.com.br/~gwidion/concrete.png

A little of the above + "secret sauce" + bump map

"secret sauce" recipe: 1.new image
2. filters->noise->hurl
3. colors->desaturate
4. layers->duplicate
5. on the bottom layer,
filters->blur->gaussian blur, radius 3 6. on the top layer, set the layer to "darken only" 7. combine the 2 noise layers
8. create new layer, fill with medium gray 9. filters->map->bump map; source = noise layer, angle curves to fit your gray range.

Hi Owen.

That tutorial creates a very regular and smooth looking pattern. Marks background image looks a lot less regular and less smooth. It looks more like an artifact from nature, like a sandy surface, where the tutorial pattern looks the opposite - the product of a mechanized process.

Thanks for chipping in, but I'm after an effect that is quiet different.

I don't remember the details now, if no one comes up with a good answer for you I'll look it up.

This and a LOT of other great techniques is taught in Michael J Hammel's The Artists Guide to GIMP Effects, probably available at a local bookstore.

If you want to come up to speed pretty quickly you should have it, and also Akkana Peck's Beginning GIMP: From Novice to Professional.

They both post here fairly often and help the rest of us. The are both wonderful writers with clearly written, beautifully illustrated texts, and there's enough material in each that is not covered in the other that you really need both. It's important to support the people that support us so that they'll keep doing it.
