Simple Fractal

Step 1.

Start a new document of any size, for this tutorial I'm using a 600x600 canvas. Fill the background layer with black (#000000).

Step 2.

Create a new layer, and make a selection near the center of the canvas that is approximately 1/6 (one sixth) of the size of the entire canvas:

and fill this selection with white (#FFFFFF):

Step 3.

Press 'D' on your keyboard to reset your foreground and background colors to black/white. Go to Filter->Texture->Grain and apply these settings:

Result:

Step 4.

Next go to Filter->Artistic->Neon Glow and apply these settings:

Result:

Step 5.

Go to Filter->Distort->Twirl and apply these settings:

Result:

Step 6.

Go to Filter->Distort->Wave and apply these settings:

Note: Press the 'randomize' button a few times, until you get an interesting shape/effect.

Result:

Step 7.

Next press Ctrl + J on your keyboard to duplicate this layer, and change this layers blending option to 'screen' as shown here:

Step 8.

Now go to Edit->Transform->Flip Horizontal:

Result:

Press Ctrl + E on your keyboard to merge these two layers together.

Step 9.

Once again, press Ctrl + J on your keyboard to duplicate this layer, and change this new duplicate layer's blending option to 'screen' just as we did in step #7.

Step 10.

Now go to Edit->Transform->Flip Vertically:

Result:

Continue to use the techniques taught above to further enhance the image. Try using the 'Overlay' blending option on some of your duplicate layers to get a different effect. The 'Darken' blending option makes some interesting looks as well. Just experiment and test different options out. Here's what I ended up with after playing around for a few minutes:

The final duplicate layer uses the "Saturation" blending option (incase you were wondering...)

Have fun!
