Watch: On a long lens the person stays the same while the background is pulled closer, enlarged and melted into soft blur: a messy background becomes blocks of color that set off the person.A line-art demo that only illustrates the technique, not finished footage.

The technique comes first, followed by the subject, scene, details and aspect ratio. Paste it straight into an image model and swap in your own subject.

Telephoto portrait, around 135mm, natural facial proportions, the background compressed and softly blurred, clear separation between subject and background. On a cherry blossom avenue, a girl in a beige trench coat looks back at the camera, the blossoms behind her compressed into a sheet of soft pink light. 4:5, eyes in focus, no messy hard edges in the background.

Common pitfalls

Shooting a face on a wide lens enlarges the nose.
Too much blur and the background carries no information.

Parameter tips

Write 85mm as the default for portraits; for an even cleaner background, write 135mm and f/2.
