Ever seen one of those really nifty, old and ripped up
graphics that contain scratches, dirt and some more dirt?
When it comes to Photoshop, we call that dirty style
"Grunge". This tutorial will teach you how to make your very
own grunge brushes.
Creating Grunge Brushes
To create your own grunge brushes, you can't simply just
make them from scratch. You need a source. In our case, the
source will be this image:

[ copy and paste this into
your Photoshop ]
It's always good to get an image that's all rusty and dirty. Using this
one, we will chop out possible grunge brushes.
Here Is How:
- Open up a canvas 365 (width) by 280 (height) pixels
respectively. Copy and paste the image above provided into
the Photoshop canvas.
- The image needs to have no color information. Convert
it to black & white by desaturating it. You can go
to image > adjustments > desaturate or you can use the
shortcut (shift+ctrl+u).
- We need the details to stand out more. Go to image >
adjustments > brightness/contrast. Set the contrast to 25.
Depending on your images later on, play around with lots
of settings until you get the desired detail.
- Now we need to select parts of it. Find a really good
place, not too dark or too light. It should have lots of
dirt. Use the rectangular marquee tool and select a part.
I selected this:

After you select the part of it, copy it onto your
clipboard (ctrl + c) and open up a new document with a
white background. On a new layer, paste what you
copied.
- Now, we need this grunge brush to not be so squared.
So select the erase tool and open up the brushes
palette. Make sure it's on the primary brushes that
Photoshop comes with. Reset it if you are on some other
brush set.
- Select the Rough Round Bristle brush. Here is
an image of what brush that is:

This brush will be used to make the edges of the squared
grunge we have all dirty and uneven. You can use other
brushes, but for now, let's use this.
- Set the brush size from 50 - 80 and erase around the
edges of current grunge. I made my work window bigger so
that I don't have to press the brush on the image exactly.
Here is what i got:

- Clean up the edges by changing your brush type to
Airbrush Dual Brush. I used mine at size 45.
- Now go to Edit > Define Brush Preset > OK. Now you
have the brush ready. This brush will be in whatever set
you were currently using, so it will be in the main
Photoshop primary one.
That was a lot of steps. But if you look at it, all you did
was desaturate, contrast, erase and that was it. Now you
know how to make you own grunge brushes! You can use these
now and apply them to your images and graphics.
We're finished. I hope this tutorial gave you an
understanding on how to make grunge brushes. This is not the
only method, but it is an effective one. Any questions?
