Examples

1. Neon Logo Enhancement

Graphic Designer
Background
A designer needs to transform a flat brand logo into a vibrant neon sign for a website hero section.
Problem
The logo lacks depth and the 'electric' feel required for the brand's modern aesthetic.
How to Use
Upload the logo PNG, select 'Neon Glow' style, set a bright cyan color, and increase intensity to 0.9.
Example Config
glowStyle: neon, glowColor: #00FFFF, glowIntensity: 0.9, glowSize: 30
Outcome
The logo now features a sharp, vibrant neon outline that pops against dark backgrounds.

2. Dreamy Portrait Softening

Social Media Content Creator
Background
A creator wants to give their portrait photos a soft, ethereal glow to match a specific artistic theme.
Problem
Standard filters are too harsh and don't provide the subtle, radiant light effect needed.
How to Use
Upload the portrait, select 'Ethereal Glow', set a warm white color, and adjust the blur to 25 pixels.
Example Config
glowStyle: ethereal, glowColor: #FFFDD0, glowBlur: 25, glowIntensity: 0.4
Outcome
The portrait gains a soft, glowing atmosphere that enhances the subject's features with a professional, dreamy finish.
