Why Watermark Your Images?
- Copyright protection: Deter unauthorized use and theft of your photographs.
- Brand awareness: Promote your brand every time your image is shared.
- Professional appearance: Watermarks signal that your work has value.
- Portfolio protection: Share previews without giving away full-resolution originals.
Tips for Effective Watermarks
- Use 30-50% opacity for a subtle, professional look.
- Place watermarks where they're hard to crop out (center or across important areas).
- Keep text short — your name or brand is usually enough.
- For maximum protection, use a larger font and lower opacity covering more of the image.
