A hyper-realistic, high-resolution photographic mockup of a massive, seamless white banner in a landscape orientation, located in the interior of the building. The banner covers an entire modern wall with no frames, edges, or visible mounting, appearing as an uninterrupted, perfectly smooth surface. The setting is a modern office with contemporary architecture, featuring clean lines and dark tones. The perspective is a straight-on, frontal view, capturing the full scale of the banner with perfect symmetry. Soft, natural daylight enhances the realism, creating subtle shadows and reflections on the building’s surface. The overall atmosphere is sleek, minimalistic, and professional, ideal for branding or advertising presentations.
