Understanding opacity
Opacity controls how transparent the watermark is.
0% = invisible, 100% = fully opaque.
15-25% for subtle branding.
30-50% for visible protection.
50%+ for previews and proofs.
Choosing the right size
Size is relative to image dimensions.
5-10% for subtle corner watermarks.
10-20% for visible branding.
Larger for preview/proof protection.
Too small becomes invisible on thumbnails.
Strategic positioning
Corner: traditional, easy to crop.
Center: maximum protection, more intrusive.
Diagonal: covers more area, hard to remove.
Tiled: impossible to crop out, most protective.
Finding the right balance
Goal determines settings.
Portfolio: minimal visibility.
Protection: maximum coverage.
Test on different images before batch processing.
