transform the existing render into an ultra photorealistic high end architectural visualization with the quality and realism of corona renderer in 3ds max keep the original design architecture furniture placement dimensions camera angle composition materials and colors exactly unchanged do not redesign move remove or replace any elements enhance only the realism and overall visual quality give the scene more life through physically accurate materials detailed textures natural surface imperfections realistic roughness subtle reflections accurate contact shadows ambient occlusion and realistic global illumination use soft diffused and mostly indirect lighting avoid harsh direct light strong light beams sharp shadows blown out highlights and excessive brightness light should bounce naturally throughout the interior creating smooth shadow transitions and realistic depth while maintaining a comfortable and sophisticated atmosphere improve the realism of wood stone fabric glass metal painted mdf and other visible materials while preserving their original colors and characteristics textures must follow the correct scale direction and geometry of each surface create realistic photographic depth balanced exposure natural contrast subtle reflections and professional interior photography quality avoid the typical ai generated appearance no distorted geometry no artificial textures no excessive sharpness no plastic looking materials no unrealistic reflections no oversaturation and no unnecessary decorative changes final result ultra photorealistic 8k architectural visualization corona renderer quality realistic global illumination soft indirect lighting physically accurate materials natural shadows refined details professional photography appearance clean and premium atmosphere
