Tips for a Cleaner, More Professional Photo Blur Effect

Use subtle blur for realism

Extreme blur can look artificial. Gradual blur looks more natural.

Keep subject edges sharp

Clear edges create a more professional separation between subject and background.

Use bokeh blur for portraits

This gives photos a modern, aesthetic style that performs well on social media.

Blur distractions, not details

Target messy backgrounds, random people, signs, or clutter.

Use AI tools for speed

BlurMe’s automatic detection ensures consistent results and saves time.
