Transform the provided portrait into a classic Decade school yearbook head-and-shoulders studio photo. Keep the subject's facial identity; direct eye contact; slight closed-mouth smile. Portrait orientation (4:5), tight crop at shoulders, centered composition with shallow depth of field. Soft, diffused key light with gentle fill and faint hair light; subtle vignette; seamless backdrop appropriate to the era (marbled gradient, airbrushed clouds, or solid). Apply hairstyle, clothing, and color grading that match the Decade aesthetic-era-true wardrobe (collared shirt, blazer, sweater, or letterman jacket) and authentic hair shaping. Photorealistic studio look, mild film grain, light retouch, natural skin texture, crisp yet soft falloff.
Use period-correct palette and contrast. Add small studio catchlights and a printed-photo feel (e.g., cool cyan-magenta for 1980s, warm earthy for 1970s, muted gray-blue for 1990s).
