Glow Dodge creates a stronger, more luminous effect than Color Dodge. It brightens the base layer while dramatically increasing color intensity, making it particularly useful for creating glowing light and intense highlights.
The Math
Glow Dodge is closely related to Color Dodge, using the brightness of the blending layer to push the base layer toward brighter, more saturated colors. The difference is in how strongly the effect builds, particularly with partially transparent brushstrokes.
It’s like Color Dodge with the volume turned way up. Instead of simply making light areas brighter, Glow Dodge pushes the surrounding colors toward a more intense, luminous result.
Core Rules of Glow Dodge
Black has little effect: Pure black produces little to no visible change, but Glow Dodge’s most important difference from Color Dodge appears when the blending color is partially transparent.
Bright colors hit hard: Lighter colors on the top layer can quickly push the base toward bright, saturated colors and eventually white.
Transparency builds: Soft or partially transparent brushstrokes can build up the effect, making Glow Dodge particularly useful for creating atmospheric halos and layered light.
Stronger than Color Dodge: The effect is more aggressive than Color Dodge, so lower opacity is often useful for keeping the result under control.
When to Use It
Magical and sci-fi effects: Great for neon energy, fire, lasers, magical effects, and other light sources that need an intense atmospheric glow.
Reflective surfaces: Use it for sharp glints and bright reflections on metal, glass, or polished surfaces.
Lighting passes: Paint with saturated orange, yellow, or other warm colors to make dramatic light sources pop against darker areas.
