Use case: photorealistic-natural. Create ONE finished photographic website background for a coherent collection named Prism studies. Premium material still-life photography of real thick optical glass and physically believable refracted sunlight, captured on a medium-format camera. Architectural restraint and tactile detail: small irregular air bubbles within cast glass, fine moulded ribs where specified, plausible beveled edges, dense colored edges, subtle surface imperfections, contact shadows, realistic internal reflections and luminous but controlled caustics. The glass must look photographed, never glossy CGI, a plastic render, a generic abstract blob, a torus or a floating chrome object. Color comes from the glass and light, never an added digital gradient or haze. Deliberate asymmetric composition, no unnecessary props, no vase, no flowers, no sphere, no letters, typography, logos, watermark, browser, UI, border, collage, contact sheet or people. Output ONE standalone edge-to-edge image in the stated aspect ratio, using the highest native detail available. Preserve the requested calm copy space; keep sharp visual detail and bright caustics out of it. Scene and framing: A portrait 3:4 studio photograph. A single short thick architectural rectangular glass column, made of dark emerald vertically ribbed cast glass, sits in the lower-right corner of a near-black stone table. The column is a straight-edged block, NOT a bottle or vase. Its top ends only 47 percent down the frame, leaving upper 43 percent quiet charcoal copy space. A large side softbox from right reveals tightly spaced ribs, irregular small bubbles and dark green optical depth, with a thin amber reflection on the far edge. Quiet minimal composition, no objects in the upper half.
