improve this existing render into an ultra photorealistic high end architectural visual absolute priority preserve the original design exactly the original render is the absolute reference keep all proportions exactly 100 identical do not change dimensions scale geometry or spatial relationships keep the exact composition and framing preserve the exact camera position viewing angle perspective and lens do not distort reinterpret redesign simplify or modify the existing architecture do not move remove resize or add any objects do not add new furniture decoration accessories architectural elements or details the final image must remain the exact same design and composition as the original render materials 100 identical do not change all existing materials must remain 100 exactly the same as in the original render do not change any material do not replace one material with another do not reinterpret or upgrade materials do not change material colours do not change textures patterns or finishes do not transfer materials from one surface to another every material must remain strictly on its original surface preserve the exact material identity of every individual element do not copy spread extend or apply a material to surfaces where it does not already exist only improve the photorealism and physical accuracy of the existing materials wall materials extremely important every wall must retain its exact original material and finish walls with plaster or stucco must remain plastered stucco walls preserve the original plaster texture colour finish and character do not transform plaster or stucco into any other material do not add new textures patterns stone wood fabric wallpaper or other surface treatments to the walls do not change one wall finish into another every wall must remain exactly as it appears in the original render fresh bright high end atmosphere the image should feel fresh bright clear clean refined sophisticated luxurious and high end create a light and fresh photographic atmosphere while preserving all original colours and materials use balanced realistic exposure maintain clear detail throughout the image use soft and refined lighting create natural depth without making the image dark avoid heavy shadows and overly dark areas avoid harsh contrasts keep the tonal balance soft clean and elegant avoid a cold sterile appearance maintain a subtle sense of warmth and atmosphere the high end feeling must come from photographic quality realism refined lighting and material accuracy never from changing the design or materials lighting photographic quality use realistic and refined lighting create natural and believable light interaction use soft realistic shadows maintain balanced exposure keep the image bright and fresh without overexposure maintain realistic highlights without clipping avoid excessive bloom or glow avoid artificial or exaggerated lighting effects avoid unrealistic reflections avoid harsh or dramatic cinematic lighting ultra photorealism ultra photorealistic architectural visualization premium high end architectural photography quality physically accurate global illumination realistic material response natural depth and dimensionality crisp but natural details realistic exposure and tonal balance sophisticated and refined photographic finish strict negative prompt wallpaper added wallpaper wallpaper texture fabric wall changed wall materials plaster converted to another material stucco converted to another material added surface texture material replacement material transfer copied materials changed proportions altered scale distorted geometry changed perspective different camera angle changed composition redesigned interior added objects removed objects altered materials changed colours colour shift changed textures changed finishes artificial reflections excessive gloss harsh contrast heavy shadows dark image overexposure excessive bloom excessive glow dramatic cinematic lighting artificial cgi appearance final non negotiable rule the final image must look like a fresh bright clear high end ultra photorealistic photograph of the exact same original render preserve 100 of the original perspective proportions architecture objects colours materials textures patterns and finishes every wall and every surface must retain its original material and finish do not add or transfer materials or textures to other surfaces do not change the design do not change the materials do not change the proportions only improve the photorealism realistic light behaviour atmosphere depth clarity freshness and overall high end photographic quality
