How do I get the blurry background look on a phone?

The Diagnosis

The blur everyone wants is mostly a distance recipe, and phones can cook it. Two moves matter more than any setting: bring the camera closer to you, and push your background farther away. The bigger the gap between those two distances, the softer the background falls — that's optics, not software. Add the focal-length trick: shooting on the phone's longer lens from farther back compresses the frame and melts backgrounds more than the wide lens ever will. Portrait or cinematic modes can finish the job, but treat them as seasoning — software blur smears hair and edges when it's doing all the work, and it reads fake precisely when the distance recipe was skipped. One caution: blur is a tool for separation and intimacy, not a default. If the background is layered and beautiful, let it live.
