## Prompt

```text
Task: Ultra-close macro hero shot of a {subject} as premium optical cast glass with diagonal light-band shadows, stronger rainbow caustics, and clean readable high-detail areas (no refraction “mush”). Subject is FULLY visible and NOT cropped. The subject is placed on the surface or floating in the air at a low altitude above the surface.
Style: Photoreal luxury product; seamless blue-gray gradient background #9FAFBC (cool, slightly blue, low saturation); glossy reflective plane; smooth clear optical glass with crisp edges, controlled internal highlights, subtle star glints; pronounced caustic streaks + vivid prismatic rainbow arcs cast onto the surface from the subject.
Framing: extreme close-up, subject fills ~90–95% of the frame, fully visible and not cropped.
Readability (fix mush): preserve crisp facial/edge details—minimize internal warping, lensing, and overlapping caustic patterns on fine features; keep the interior visually “quiet” so the surface sculpt reads clean.
Optical control: low-distortion, low-aberration glass look (reduced dispersion inside the object) with strong external caustics on the surface.
Lighting: broad diagonal soft light bands; long soft cast shadow with smooth penumbra; rainbow caustics should be stronger and more numerous around the base and across the floor. Clean white color.
Environment control: seamless studio only; gray/black flags controlling reflections; no window/room elements.
Negative prompt: excessive refraction, heavy distortion, lens effect, warped facial features, chaotic highlights, milky/foggy glass, random reflections, window, interior, wall corner, faceted, polygonal, low poly, text, watermark, clutter
