Blur the faces of the strangers in the background of this photo, but keep [ME AND MY GROUP] in the foreground sharp and completely unchanged.

The blur should look natural and match the depth of field of the photo.

Ask for a gentle blur so the scene still looks natural.

What you will get

Your photo with the faces of passers-by in the background softly blurred to match the depth of the scene, while you and your group stay sharp and unchanged.

Why it works

Privacy blurs should protect strangers without spoiling your photo, so the prompt blurs background faces and keeps you and your group sharp. Matching the photo’s depth of field makes it look natural, and a gentle blur, as the tip says, keeps the scene real.

Common mistake

Someone in your group gets blurred.

Fix: Describe who to keep, such as “the two people in red jackets in front”, so the right faces are protected.

Also watch for

The blur looks like a smudge. Ask for a gentle, lens-like blur that matches the rest of the photo, not a pixelated block.
A face is missed. Zoom in and check every background face. If one is still clear, run it again or blur it by hand.

Try a variation: blur one person only

Name a single person or area to blur, such as the man on the left edge, and leave every other face alone.

Check again at full size. Blur every background face that can still be recognised, including faces in reflections, and keep my group unchanged.
