When to Use Watermarks
Photography Portfolio

Pro Tips for Watermarking
Position Strategically
Place watermarks where they're hard to crop out but don't obscure the subject.
Use Appropriate Opacity
30-50% for subtle protection. 80-100% for prominent branding. Balance visibility with aesthetics.
Consider Diagonal Placement
Diagonal watermarks across the image are harder to remove than corner placements.
Use Transparent PNG Logos
Upload logos with transparent backgrounds for professional, seamless watermarks.
Maintain Consistency
Use the same watermark style across your portfolio for brand recognition.
