Light leaks add an unexpected warmth and artistic flair to photographs. While these colorful glares typically occur when unwanted light enters a camera lens, they create such appealing visual effects that many photographers seek to recreate them digitally.
This technique uses gradient fill layers with screen blending mode to simulate authentic-looking light leaks in any color combination. The method offers complete control over placement, intensity, and direction while remaining fully adjustable.

Practical Tips
Here are key techniques to create convincing light leak effects:
- Set the blending mode to Screen before creating the gradient to see the effect immediately
- Use the "Foreground to Transparent" gradient preset and customize colors from white to yellow to red
- Keep all color stops clustered toward the left side of the gradient editor for realistic falloff
- Position light leaks to peek from image edges rather than covering the entire frame
- Duplicate gradient layers to create multiple light sources from different directions
