ultra photorealistic enhancement of an exterior render of a wedding restaurant preserve the exact original architectural design structure proportions geometry layout landscape arrangement and camera angle do not redesign modify add or remove architectural elements maintain full authenticity of the existing project focus exclusively on improving rendering quality lighting realism and material accuracy upgrade all surfaces to extremely high resolution pbr materials with physically accurate properties albedo roughness normal displacement reflections materials must appear precisely crafted and architecturally believable natural stone with micro surface detail realistic wood grain with subtle variation polished metal with accurate reflections architectural glass with natural transparency and reflections concrete with fine imperfections enhance global illumination and physically accurate lighting use natural daylight with soft shadows realistic ambient bounce light balanced exposure and subtle reflections improve depth contrast and micro detail while keeping a natural photographic appearance increase rendering fidelity and clarity ultra sharp textures high dynamic range lighting realistic reflections accurate shadow softness and natural color grading typical of high end architectural photography vegetation should appear natural and highly detailed with realistic leaf translucency and natural color variation outdoor environment lighting should feel atmospheric and cinematic but still natural professional architectural visualization quality similar to v ray corona renderer or unreal engine archviz renders clean surfaces precise materials and premium visual realism photorealistic architectural visualization ultra detailed materials pbr textures global illumination ray traced reflections hdr lighting cinematic daylight realistic shadows ultra sharp focus high dynamic range professional archviz render 8k quality extremely detailed realistic materials architectural photography quality no redesign no new architecture no style change no geometry change no distortion no cartoon materials no low resolution textures no artificial plastic surfaces
