I found this tutorial here:
http://www.chainstyle.com/tutorials/fibers.htmlI usually copy and paste older tutorials like these into my google notebook, for the concern they may not exist tomorrow. Anyway, I just substituted GIMP Ripples for PS Waves, and faked the settings (tinkered until the results were similar). Don't expect your results to be identical to the author's because of the way your difference clouds turn out.
What would this be used for? Water effects, mostly. With the right Curves settings applied, you can give it a molten metal look and apply a radial blur for a brushed metal look.
I thought I would share this after searching for alternatives for converting a PS tutorial to GIMP.
The GIMP Translation:1. Open a square image (equal width & height - any size) with a white background.
2. Go to
Filters - Render - Clouds - Difference Clouds and apply these settings:
3. Select the
Blend Tool and use the following settings (there is no right or wrong here - your effect will just appear slightly different than mine and the example in the web tutorial, so don't worry if your example differs than the one shown here):
Using the Blend tool with default black and white colors, mode set to Difference, shape = Bi-linear, follow a similar lay-out of the red arrows, until you get a similar (not perfect) result:
4. Go to
Filters - Distorts - Ripples and apply the following settings:
5. Go to
Layer - Transform - Rotate 90 degrees clockwise.
6. It was at this point I needed to decide how "fibrous" I wanted my
fibers to be. Did I want them to be bristly (coarse) or cottony (smooth). You, too, need to decide which way you want your
fibers to look. If you want coarse:
6a: Apply
Filters - Artistic - Cubism:
Then apply
Unsharp Mask:
6b. If you want smooth
fibers, apply a
Gaussian blur of 5px, then apply the
Unsharp Mask settings you see above.
I went the coarse route, so my
fibers look like this, at this point:
7. The next step involves
Filters - Distorts - Wind at the following settings twice (once for each direction):
8. Now
Filters - Blur - Motion Blur:
9. Now a little darkening is needed. We do that by applying
Colors - Levels :
10. Then a final Ripples effect -
Filters - Distorts - Ripple:
11. And now crop the outer edge, but maintain a square image. Using the Crop tool, I set my crop area to 455 x 455px, then click the image. You're done!
