Optical Glass Hero Close-Up

Task: Shoot ultra-close-up heroic portraits of the subject, presented as high-quality optically cast glass with diagonal light band shadows, stronger rainbow caustic lines, and clear, readable high-detail areas (no refraction "blur"). The main body must be fully visible and not cropped. The main body is placed on the surface or floats low above the surface. Style: Realistic luxury products; Seamless blue-gray gradient background #9FAFBC (cool tones, slightly blue, low saturation); Glossy reflective plane; Smooth transparent optical glass with clear edges, controlled internal highlights, and subtle starlight sparkles; The main body projects distinct caustic stripes + vivid prism rainbow arcs on the surface. Composition: Extreme close-up, with the main subject occupying about 90-95% of the frame, fully visible, without cropping. Readability (Fixing Blur): Preserves clear face/edge details—minimizing internal distortion, lens effects, and overlapping caustic patterns on fine features; Maintain a visually "quiet" interior, making the surface sculptures clearly recognizable. Optical control: glass appearance with low distortion and low aberration (reducing internal dispersion of objects), with strong external caking on the surface. Lighting: Wide diagonal soft light band; Long soft shadows with smooth penumbra; Rainbow caustic lines should be stronger and more abundant at the bottom and on the ground. Pure white. Environmental control: Seamless studio only; Gray/black baffle controls reflection; No window/room elements. Negative Notes: Over-refraction, severe distortion, lens effects, distorted facial features, chaotic highlights, milky/blurred glass, random reflections, windows, interiors, corners, multifacets, polygons, low polygons, text, watermarks, clutter.
