Digital Star Effect Photoshop Tutorial ~ Goblog

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 2

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

Step 3

Select the new layer and apply a Mosaic filter (Filter> Pixelate> Mosaic) with a Cell Size of 8 square.

Step 4

Apply a Find Edges filter (Filter> Stylize> Find Edges).

Step 5

Apply a Median filter (Filter> Noise> Median) with a Radius of 2 pixels.

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.

Step 7

Invert (Image> Adjustments> Invert or Ctrl+I).

Step 8

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

Step 9

Apply a Find Edges filter (Filter> Stylize> Find Edges).

Step 10

Invert (Image> Adjustments> Invert or Ctrl+I).

Step 11

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

Step 12

Activate the top layer and apply a Motion Blur filter (Filter> Blur> Motion Blur). Set the angle to 45º and the distance to 100 pixels.

Step 13

Apply an Auto Levels (Image> Adjustments> Auto Levels or Shift+Ctrl+L)

Step 14

Now we’re going to do the same steps againusing a different Motion Blur angle on a different layer. Activate the layer below (Layer 1 copy 2) and apply a Motion Blur filter (Filter> Blur> Motion Blur). Simply type a "-" sign in front of the 45º and click OK.
