Transform ordinary photos into spectacular light displays by repurposing "throwaway" images from your photo shoots. Screen blending mode eliminates dark areas while preserving bright elements, allowing you to layer sparklers, light trails, and even galaxy textures to create dramatic special effects.
This technique works with any glowing or bright elements - from failed test shots to stock images of stars and nebulae. The key is understanding how to manipulate darks and lights to blend seamlessly with your main subject.

Practical Tips
Key techniques for creating convincing light effects using existing images:
- Use File > Scripts > Load Files into Stack to combine all source images into one document for easier management
- Change blending mode to Screen on light effect layers - this makes dark areas invisible while preserving bright elements
- Apply Levels adjustment (Ctrl/Cmd+L) to make darks even darker when using Screen mode, ensuring cleaner light isolation
- Create black layer masks (Alt/Option+click mask icon) then paint white only where you want effects visible for precise control
- Transform and rotate light elements (Ctrl/Cmd+T) to match the flow and direction of your main composition
