When blur is the right choice
Blur suits faces in a crowd, people in the background of a listing photo, or a cluttered desk behind a product shot. The picture keeps its composition while the sensitive part becomes unrecognisable.
Blur is not a substitute for redaction when the hidden content is short, high-contrast text such as a password, a card number or a one-time code. A heavy blur over large text can sometimes be partially reversed, so use Black box for those.
