Quick & Easy Grunge

Start off with a new image 500x100 (works with any size image), press the letter "D" to set colors to default then goto "filter > render > clouds" then "filter > noise > add noise" use settings below.

Now goto "filter > stylize > emboss" use settings below.

Now go to "filter > distort > diffuse glow" use settings below.

Now Duplicate the background Layer, with the duplicated layer selected, goto "filter > artistic > palette knife" use settings below.

Now set your duplicated layer opacity to about 80% then merge together with "ctrl + e" you should have something like this.

Now go to "select > color range" when the window opens you will see a black rectangle click on it, now click on it a couple of more times in different places, you will notice the image changes, click so you get something similar to the image below, also change fuzziness to about 50.

This is how my image looks once i pressed ok.

With your selection still selected from the color range, create a new layer and fill with the color black, then press "ctrl + D" to deselect, now select your background layer and press "ctrl + u" when the box opens put a "tick" in the colorize box and play with the sliders until you decide on a color, here's my finished result with some texted added.
