Star Diffusion Photoshop Tutorial
Step 1: Open a photo into Photoshop
Begin by opening a photo into Photoshop. To do this, choose File> Open, browse for the file, and click OK.
Step 2: Create a duplicate of the layer
Press Ctrl+J or choose Layer> Duplicate Layer to create a duplicate of the Background layer. You should now have a new layer. Double-click on the text of this layer and you will be able to edit the layer name. Name this layer Star Diffusion.
Step 3: Add a layer mask
Add a layer mask to the Star Diffusion layer by clicking on the Add Layer Mask button in the Layers pallet or by choosing Layer> Layer Mask> Reveal All. You should now have a white thumbnail beside the layer mask.
Step 4: Create a copy of the image as a layer mask
After you change the layer name, the layer mask will be deselected. Before we continue, click on the layer mask thumbnail in the Layer pallet to activate it. It should have a white border around the thumbnail indicating that it has been selected. With the layer mask selected, choose Image> Apply Image. In the Apply Image tool, simply click OK to use the default settings. The layer mask should now have a copy of the image.
Step 5: Change the blending mode to Screen
In the Layers pallet, change the blending mode of the Star Diffusion layer to Screen.
Step 6: Duplicate the Star Diffusion layer and group the two layers
Make sure that the Star Diffusion layer is selected then press Ctrl+G or choose Layer> Group Layers. The layer group put the layer into a group to keep the layers organized. Double-click on the group name and rename this group to Star Diffusion. Now, select back the Star Diffusion layer and press Ctrl+J or choose Layer> Duplicate Layer to duplicate the layer.
Step 7: Apply a diagonal motion blur
Select any one of the two Star Diffusion layer and choose Filter> Blur> Motion Blur. Set the Angle to -45º and adjust the distance according to the length of the streaks that you want. If you're working on a high resolution image and the distance setting does not let you create streaks long enough, use the highest setting, click OK, and then press Ctrl+F to repeat the filter until you get the length you desire.
Step 8: Apply the opposite diagonal motion blur to the other Star Diffusion layer
Now select the other Star Diffusion layer that you did not apply the motion blur effect to. Choose Filter> Blur> Motion Blur and use the same distance settings as before but use the opposite angle setting by simply removing the - from the angle (ex. 45º instead of -45º). If you're working on a high resolution image and you had to repeat the filter in the previous step to get long streaks, don't forget to repeat the filter again so that this layer has the same streak length as the other Star Diffusion layer.
