How do I blur the background of a product photo?

Background blur is a distance game, not a filter. A lens throws the background out of focus when the background sits far behind the point of focus, so the whole technique is arranging distances: camera close to the product, product far from everything behind it. Do that and even an ordinary phone lens blurs the backdrop for real, no software involved.

The setup that produces real blur

Put the product near the front edge of a table and push the table away from the wall, or shoot along the table’s length so the room stretches out behind. Get the phone close to the product, as near as it will still focus, and switch to the 2x or telephoto lens rather than the wide one, since longer lenses compress and blur backgrounds more. Tap the product to lock focus on it. The background does not need to be pretty, only distant: a string of window highlights or a shelf two metres back melts into exactly the soft wash people mean by “professional blur”.

Why the software shortcuts disappoint

Portrait mode and blur filters estimate where the product ends and paint blur behind their guess. On faces they are decent; on products they smudge bottle necks, straps, glass, spouts and the edges of labels, and the fake blur is uniform where real blur deepens with distance. For photos meant to sell something, a smeared label edge costs more than the blur adds. If you must blur in the edit, zoom to every edge afterwards and be honest about what you see.

Keep some restraint either way. A listing photo usually wants the whole product sharp and the setting readable; heavy blur suits mood shots for social feeds more than main marketplace images.

Blur that comes built into the scene

There is a third route: have the depth of field rendered rather than shot. BrandStills turns two or three plain phone photos of your product into finished scenes where the blur behaves like real photography, because the scenes are built with photographic depth: a sharp product against a softly blurred cafe, a dusk city street, or a shallow-focus botanical set. Your label, colours and proportions stay locked, edges stay clean, and each image takes about a minute, which beats masking blur around a bottle handle by hand.
