How to Edit in Stardust in Photoshop
Adding a star effect to digital images is fairly easy to create from scratch in Photoshop. ( Images)

Adding stardust effects to your Photoshop images can be achieved in a few simple steps. Starfields and stardust can be created in Photoshop from scratch without needing a photograph from the Hubble Space Telescope. You will primarily use the noise filter and layer blending modes.

  2. 2

    Create a new blank layer in Photoshop. Name the layer Stardust.

    Make the new blank layer by clicking on the new layer icon in the far right bottom of the layer palette (to the left of the trash icon). You may also make a new layer by using the layer palette drop down menu on the right hand side arrow and selecting "new layer".

  3. 3

    Fill your new layer with black. Go to Edit>Fill and choose black.

    Apply the Noise Effect to your new layer. Click on Filter<Noise<Add Noise. For your settings, choose monochromatic, gaussian and you will also need to set the number. For lower resolution images, choose the number 30, but for higher resolution images, you may need to raise the number to 150 or higher, based on the appearance for your digital image. It may take a few tries to reach the best number to use for your image.

    Switch the Layer blending mode to "Screen" mode by going to the layer palette and selecting a new black layer. At the top of the layer palette you will see the sub-menu which will read "Normal". Scroll down on the options using the arrow next to it, until you reach the word, "Screen".

    Applying multiple layers of this effect and varying the size of your noise filter will give a more varied appearance to your stardust. (Jupiterimages/ Images)
  6. 6

    Apply the Levels effect to your black stardust layer by clicking Image<Adjustments<Levels. Slide the arrow to the left, until the stardust begins to fade and looks more naturally blended with your digital image. There is no exact number, it will vary based on the background of the image you are applying the effect to.

  7. 7

    Apply a mask to your black layer to hide areas where you do not want the stars to appear on your digital image. Do this by selecting the "add mask icon" at the bottom of the layers palette. A white mask will appear next to your black stardust layer. Using the paintbrush tool, set to black, paint out the areas where you do not want to see the stars appearing on your image. For greater detail on using masks, refer to the help menu, under masks.

    To create stardust variations experiment with other filters such as radial blur, or motion blur, after following these steps. ( Images)
