*Using PS CS2
*12 quick steps
This tutorial was in response to a question posed by hsbfc, and seconded by roughseas. Here's to you both! ;)
When I started this tut, it was meant to be a correction to THIS tutorial by lizabeth0606, seeing as how her tutorial really didn't work, but once I got started, I changed it around a good bit to make it different enough to call it mine. Ready? Here we go...
01. Open a new file and fill the background layer with solid black (#000000).
02. Add a new layer.
03. Pick the PAINTBRUSH tool, and set it to a 1-2pt brush tip at 100% hardness. (I used a 1pt tip in the examples.) With that brush tip, draw a few random lines around your canvas. Make them as oddly-shaped and squiggly as you want!
04. Duplicate that layer and rotate it. Do this as many times you like until you're satisfied with how it looks.
05. Once you're happy with your base, hit SHIFT + CTRL + ALT + E. (This will duplicate all of the layers into one merged image on its own layer.)
06. On that merged layer, go FILTER > ARTISTIC > CUTOUT.
Number of Levels: 3
Edge Simplicity: 1
Edge Fidelity: 3
**NOTE: If you don't like the way the cutout filter works for you, you can use the rough pastels filter instead.
Go: FILTER > ARTISTIC > ROUGH PASTELS.
Stroke Length: 15
Stroke Detail: 3
Light: (default is Bottom, but you can play with this & it won't make much difference)
*in this example, I chose to use the Cutout filter.
07. Duplicate the layer you've applied the filter to and set it to SOFT LIGHT at 25%.
08. Duplicate your soft light layer, rotate it and set it to LIGHTEN at 75%.
09. Do another SHIFT + CTRL + ALT + E.
10. Go: FILTER > BRUSH STROKES > SPATTER.
Spray Radius: 8
**Leave this layer at the normal blend mode.
11. Do another SHIFT + CTRL + ALT + E.
12. Go: FILTER > BRUSH STROKES > SPRAYED STROKES.
Stroke Length: 0
Spray Radius: 25
Stroke Direction: Right Diagonal.
**Set this layer to SCREEN.
Now you're ready to crop your scratch texture to the desired size and have fun! XD Enjoy!
