I’ll be working on the 2nd image. Base on that image, I start a new document 640×480.
Now open the mud image up, on the dirt image, do a CTRL+A to select all, then go to the new document you just created and press CTRL+V to paste the image.
The cracks are dark, so we’ll invert the image so it becomes white, this will give it a better explosion effect. so go to Image->Adjustment->Invert (or press CTRL+I).
Now use the eliptical marquee tool and make a large round selection on the image. Hold SHIFT while you create the selection to make a perfect round circle.

Now go to Select->Inverse,
Then hit Delete so you are left witha circle from the mud image. DO NOT DESELECT YET.

Now, while you still got your selection, go to SELECT->INVERSE again to select the shape.
Now go to Filter->Distort->Spherize. Set amount to 100%. Then do it again, this time, 50%. You can now deselect.
Now, lets fill the background layer (the layer underneath the mud layer) with black.
Then go to Layer->Flatten Image
Now go to Filter->Sharpen->unsharp Mask.
Amount: 500%. Radius:
1.7px. Threshold: 122 levels
- Go to Filter->Distort->Polar
Co-ordinates.
Options: Polar to Rectangular. VIEW
Go to: Image->Rotate Canvas->90CW. VIEW
Apply: Filter->Stylize->Wind
Method: Wind. Direction:
From the right. Hit CTRL+F to reapply. VIEW
Go to: Image->Rotate Canvas->90CCW. VIEW
Finally, apply Filter->Distort->Polar Coordinates.
Options: Rectangular to Polar.
There you go, now all you do is just play around with colors, by either using Image->Hue and Saturation, or Image->Color Balance.
I use color balance in the image below.
This tutorial will work for basically and image with textures such as cracks. Here are a few variations.
