GPT Image 2.5 Sunburst プロンプト - ハイキーなフィルム粒子の物思いに沈む座像

Minimal high-key fashion editorial photograph, 4:5 portrait format, full seated figure. An adult woman, 25 or older, sits slightly left of center on a seamless white studio floor, with generous negative space above her head. Her hips rest on the floor and her torso leans backward. The arm on image left extends behind her, palm planted and fingers spread to support her weight; the other arm is largely obscured. Both knees are bent, raised, and staggered, the nearer thigh forming a diagonal. Her feet remain close together, directed toward the lower right. Keep every fingertip and both feet inside the frame. Very dark long hair swept back behind her body, slightly damp and separated into strands, with fine loose tendrils across her face. Her head is gently lowered and turned toward image right, eyes looking down, lips softly closed, expression quiet and contemplative. Cool editorial makeup, elongated eyeliner, muted taupe eyeshadow, and subdued rose-brown lips. Light skin with a cool pink undertone, natural pores, and subtle tonal variation. Slightly elevated camera with a gentle downward angle, an estimated 50–70mm full-frame lens and f/5.6–f/8 appearance. A large soft light from the front-left and white studio bounce produce gentle skin gradients and pale gray contact shadows beneath the palm, hips, and feet. Subtle film grain and natural sharpness. She has just sat down between shots, her lowered gaze lingering for a moment. Negative: bodysuit, corset, halter, gloves, arm sleeves, latex suit, patent outfit, ankle bands, extra limbs, plastic skin, text, watermark.
