Prism portrait

THE PROMPT

An adult woman with short black curls wears a plain charcoal high-neck jacket. She holds a clear triangular prism near her shoulder while looking past the camera. Waist-up portrait, asymmetric framing, natural unpainted skin, a textured studio wall receding behind her, one sharply focused eye and gently falling depth of field. Visual medium: High-end photographic realism, believable tactile materials, natural lens perspective, controlled depth of field and subtle fine grain. Keep texture clear without waxy smoothing. Palette: saturated amber, muted cyan, charcoal. Lighting: an amber side light and cyan rim light with deep soft shadows. All human or humanlike figures are clearly adult and fully clothed. Original character and object designs. One coherent finished image, with no added lettering, logos, signatures or watermarks.
