Digital Star Effect Photoshop Tutorial Creating the Dots – Part One
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.
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).
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). Creating the Dots – Part Two
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.
