create an ultra photorealistic 8k architectural visualization of this modern restroom area with the visual quality of a professionally produced 3ds max corona renderer interior do not change anything in the scene preserve the exact architecture camera angle perspective composition toilet cubicles partition walls black toilets flush plates integrated planters and plants wooden wall panels stone tiles black door ceiling spotlights proportions and all existing details do not add remove reposition resize or redesign any element keep all existing colors and material tones exactly as they are in the reference image maintain the current warm natural wood off white surfaces beige stone flooring dark door black sanitary elements and greenery do not alter the wood color or grain direction improve only the realism lighting behavior materials shadows reflections and overall render quality keep the same exposure and brightness level as the original image do not make the scene brighter refine the existing ceiling spotlights with realistic corona light distribution soft falloff subtle indirect illumination accurate global illumination natural light bouncing between partitions realistic contact shadows and better depth make the wood surfaces highly realistic with fine natural grain subtle roughness micro bump and realistic pbr response while maintaining the exact original texture direction and color improve the stone flooring with subtle surface variation realistic joints and micro texture give the black toilets and door realistic matte finishes with controlled reflections make the plants naturally detailed without changing their size species position or quantity use corona renderer global illumination ray traced indirect lighting realistic ambient occlusion physically accurate pbr materials soft contact shadows subtle reflection variation realistic roughness photographic tonemapping highlight compression natural contrast high resolution textures clean anti aliasing and professional 8k detail the final result should feel more alive dimensional and physically believable like a high end architectural photograph created by a professional visualization studio not an ai generated render strict no design changes no camera changes no new objects no people no decoration changes no material replacement no color changes no brighter exposure no excessive warm yellow tint no overexposure no exaggerated shadows no excessive bloom no hdr look no oversaturation no plastic surfaces only upgrade the existing render to corona renderer level photorealism
