First, we'll transform a photo into a series of circles. This is done by combining several filters.
Step 1

Open an image to edit.

Step 6

To reduce the size of the dots, we'll use the Maximum filter (Filter> Other> Maximum) to enlarge the white areas. Use a Radius of 1 pixel.

The thumbnail in the layers pallet should turn from white to black.

Now we'll create the outline of the circles. This layer will also be reused to create the star effect in the next page.

Step 8

Duplicate the top layer (Layer> Duplicate Layer or Ctrl+J) and change the blending mode to Screen.

The Star Effect
In this section, we'll add the star effect. This is done using the motion blur filter.

Step 11

Duplicate the top layer twice (Layer> Duplicate Layer or Ctrl+J).

You should now have a total of 5 layers.

Step 12
