Vertical (ratio 3:4) Minimalist Exhibition Poster in 4K Resolution

Design a vertical (ratio 3:4) minimalist exhibition poster in 4K resolution, featuring an ultra-light cool gray background (#f4f4f4). Centrally positioned is a floating hexagonal prism, shaped like a beveled sculpture, rendered as translucent crystal with subtle grainy texture. The object exhibits a gradient transitioning from Electric Blue (#0077FF) to Satin Silver (#C0C0C0), lending it a refined opalescent finish. Softbox lighting from above creates elongated, diffused colored shadows and a faint luminous glow surrounding the prism. The design incorporates overlapping text, where letters obscured by the crystal appear subtly blurred with a gentle Gaussian effect. • The main title, set in bold Electric Blue geometric sans-serif typography, appears centered, partially concealed by the prism, with affected portions softly blurred through the translucent surface. • Beneath this, the subtitle is displayed in bold all-caps modern sans-serif typography in pure black, reading “THE FUTURE OF DESIGN.” It too has segments overlapped and blurred through the prism, while uncovered sections remain sharp. The composition overall emphasizes generous whitespace, balanced visual arrangement, precision focus, and a high dynamic range (HDR) aesthetic.
