Here is a useful trick for selectively placing stars or light sources in Topaz Star Effects. This application will allow you to have the freedom to place the ‘light’ wherever you want within the application. Normally when a photo is brought into Star Effects, a brushed on white spot or naturally occurring light source cannot be changed or moved around once it is applied. This tutorial will allow you to create a star that can easily be placed anywhere in the image!
1. Go into Photoshop (CS) any version
2. Load the image you would like to apply a star or sun to
3. Create a new layer (Shift + Ctrl/Cmd + N)
6. With the black layer highlighted in the layer panel, bring it into Topaz Star Effects and chose the star of your choice. I chose the ‘Lamp Post I’ preset and tweaked it to my liking in the adjustments panel as shown:
8. Change the black layer mode from Normal to Screen:
Now you have a star you can totally control! Select the star layer and move it anywhere you want. Go into transform mode (Ctrl/Cmd + T) to rotate, distort etc. You can also reduce the opacity as well as duplicate the layer multiple times to add more than one star.
