Understanding Light Matching
Consistent lighting makes AI-generated scenes believable. Mismatched lighting is the #1 giveaway of artificial imagery. Key principle: Product shadows must match scene lighting direction.Using the Relight Tool
Intensity Levels
None
Keeps original product lighting unchanged
Low
Subtle adjustment for minor mismatches
Medium
Balanced relighting for most cases
High
Strong relighting for dramatic scenes
Quick Workflow
- Generate scene first
- Check shadow direction
- Apply Relight if needed
- Regenerate for perfect match
Common Lighting Scenarios
Original: Studio lighting
Scene: Side window
Fix: Relight Medium-High
Scene: Side window
Fix: Relight Medium-High
Color Temperature
Quick Reference
| Scene Type | Temperature | Relight Setting |
|---|---|---|
| Morning light | Cool | Low + “morning” |
| Midday sun | Neutral | Medium |
| Sunset/Evening | Warm | High + “sunset” |
| Indoor lamps | Warm | Medium + “warm” |
Troubleshooting
Common Issues
- Hard shadows: Original has harsh lighting → Use diffused lighting keywords
- Double shadows: Conflicting light sources → Increase Relight intensity
- No shadows: Overlit original → Add “dramatic lighting” to prompt
- Wrong direction: Mismatch with scene → Always use Relight tool
Pro Tips
- Match time of day in prompt with Relight level
- Use “soft lighting” for subtle shadows
- Specify light source: “window light”, “overhead lighting”
- Generate multiple versions to compare
Remember: Relight tool only adjusts intensity, not direction. Plan your scene lighting accordingly.
