Sunburst Portraits: Two Prompt Paths — Realistic and Artistic

A side-by-side portrait style comparison using the Sunburst precision tier of gpt-image-2.5: the same subject setup is run through two prompt paths, "realistic photography" and "artistic painting," to observe how this tier differs in skin texture, lighting gradation, and material rendering. Sunburst targets high-precision creative work, with longer per-request latency; it trades speed for finer detail reconstruction, making it suitable for final-stage finished-grade portrait references, brand character visuals, and social media avatars, but unsuitable for low-latency batch sketch exploration. This piece uses the text-to-image pipeline, with the aspect ratio fixed at 16:9, quality tier set to high, and output in webp; reference images are not required, so image_urls does not appear in the submission parameters. Developers can treat this entry's actual input snapshot as a prompt-writing template: describe the subject, light direction, lens, and materials, rather than stacking style words.

A realistic half-body portrait of a woman in her early thirties, standing near a large industrial-style window, her body turned three-quarters toward the camera, her gaze calm and direct. Soft overcast daylight from the left forms a broad key light with gentle falloff; subtle warm bounce light fills the shadow side. Visible skin texture, including pores and fine vellus hair, natural under-eye tones, no retouching. Short dark hair with individual strands catching the rim light, minimal makeup, a dark gray knit sweater with visible fiber detail. Shot on an 85mm lens at f/2, shallow depth of field, background of a concrete wall and blurred window mullions. Neutral palette, slightly reduced saturation, high dynamic range, crisp micro-contrast. Horizontal 16:9 composition, subject placed toward the right, with ample negative space on the left.
