When to use it

Portraits, products, food; when the background is messy.

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.

Wide-aperture shallow-focus portrait, 85mm f/1.4, a park path at dusk: a girl in an off-white sweater turns to look back, focus on her eyes, the fallen leaves and streetlights behind her melting into creamy round bokeh, clear separation between subject and background. 4:5 vertical, natural skin tones.

Common pitfalls

Hair edges look cut out and stuck to the background.
Focus lands on the tip of the nose or the ear.

Parameter tips

Say where the focus is; the farther the background from the subject, the softer it gets.
