create a high end photorealistic architectural interior visualization based exactly on the provided png reference image the goal is to transform the png sketchup style reference into a photorealistic client presentation render while preserving the architecture structure geometry proportions camera angle materials and all visible elements 100 exactly as shown in the png reference with one specific correction only add the sloped ceiling geometry exactly as intended in the design this is not a redesign this is not a reinterpretation this is not a creative improvement this is not a furnishing concept this is only a photorealistic version of the same scene with the missing sloped ceiling correctly completed 1 absolute preservation lock highest priority preserve 100 exactly original wide camera angle original perspective original field of view original composition room proportions wall positions floor level staircase position and geometry staircase width angle and visible step layout black metal stair railing position and rhythm central steel column position height thickness and proportions all visible steel beam positions all visible steel beam dimensions all visible steel beam orientation wooden clad underside of the mezzanine window position and proportions radiator position left side door edge and handle position lower wooden floor direction all structural relationships exactly as shown in the png reference everything must remain exactly the same as in the png reference image except for the required completion of the sloped ceiling do not redesign anything do not reinterpret anything do not improve anything beyond photorealistic rendering and the explicit sloped ceiling completion do not add anything unrelated do not remove anything do not move anything do not resize anything do not replace anything do not simplify the steel structure do not change the construction logic 2 only allowed architectural correction add the missing sloped ceiling the current flat white ceiling area visible in the png reference must be corrected into a sloped ceiling the sloped ceiling must be clearly visible above the window area and upper right part of the room geometrically integrated into the existing space consistent with the spatial logic shown in the target concept rising upward in a clean diagonal slope visually connected to the upper part of the room and mezzanine opening architecturally believable simple and clean finished in white plasterboard white drywall important the sloped ceiling is the main missing element that must be added it must look like a natural part of the original architecture it must not change the rest of the room it must not trigger any further redesign the slope should read as a white sloped drywall ceiling plane replacing the incorrect flat ceiling plane in the png image 3 scene description wide interior view of an apartment with a newly inserted steel load bearing mezzanine gallery structure the scene contains a central dark steel column dark structural steel beams a warm wooden clad underside of the mezzanine a wooden staircase on the left side black metal railings a large window with radiator on the rear wall warm wooden plank flooring light off white walls a white sloped plasterboard ceiling a clean empty architectural interior the space must remain empty technical clean and minimal 4 material lock steel structure render all steel elements as dark anthracite to black structural steel matte to satin finish realistic powder coated appearance physically believable roughness subtle edge highlights realistic weight and thickness no chrome effect no mirror reflections no rust no decorative patina the steel must look solid structural and technically credible wooden floor render the lower floor as warm natural wooden planks realistic wood grain visible board joints satin finish subtle tonal variation natural brown tone not too orange not too yellow not glossy keep the floor direction exactly as in the png reference staircase render the staircase as warm natural wood realistic wooden treads same geometry and position as reference clean architectural appearance natural satin finish realistic grain do not redesign the staircase underside of the mezzanine render the underside of the mezzanine as wooden cladding warm natural wood realistic grain clean board or panel structure subtle tonal variation believable material thickness important the underside of the mezzanine must remain wooden cladding walls render the walls as light off white plaster subtle fine texture clean realistic surface no wallpaper no wall panels no feature wall no decorative finish ceiling critical render the ceiling as white plasterboard white drywall the sloped ceiling must be white smooth painted finish simple and neutral no wood finish no concrete finish no decorative ceiling treatment no added lights no ceiling fixtures important the sloped ceiling must be a white drywall plasterboard architectural element do not make it flat do not keep the incorrect flat ceiling plane do not change it into wood or concrete window and radiator render the window and radiator as white painted window frame same proportions and position as reference clean glazing white painted radiator below realistic but visually secondary do not redesign them railings render visible railings as black painted metal matte finish slim vertical balusters same layout and rhythm as in the png reference no redesign do not invent extra railing elements 5 strict no add rule critical absolutely nothing may be added to the final image except the required sloped ceiling correction this means no furniture no decor no accessories no lighting fixtures no pendant lights no spotlights no led strips no wall lamps no artworks no shelves no cabinets no tables no chairs no sofas no rugs no curtains no blinds no plants no flowers no people no pets no construction tools no clutter no extra architectural details no extra beams no extra columns no extra windows no extra doors no additional glass elements no glass railings unless already clearly present in the source image no hidden creative enhancements if something is not visible in the png reference do not invent it if something is not explicitly requested do not include it only add the sloped ceiling nothing else 6 lighting lock use soft natural daylight only lighting must be realistic neutral to slightly warm not yellow not cold blue balanced soft and natural physically believable bright enough to read the steel wood and ceiling geometry clearly add realistic global illumination accurate contact shadows soft shadow depth below the mezzanine natural material response on wood steel and plasterboard avoid dramatic cinematic lighting artificial lighting mood visible lamps spotlights pendant lights led strips hdr effect overexposed highlights excessively dark shadows 7 photorealism boost upgrade the png reference into a professional photorealistic render using physically based materials realistic global illumination accurate contact shadows realistic steel roughness natural wood grain realistic wooden cladding texture realistic plasterboard ceiling surface realistic wall texture correct scale perception natural exposure balanced contrast crisp but not artificial detailing subtle 1 2 photographic grain to avoid cgi plasticity the result must look like a clean client ready architectural visualization not a stylized concept image 8 absolute negative prompt do not add anything do not change anything do not remove anything the only allowed modification is the completion of the white sloped plasterboard ceiling do not add furniture decor accessories artworks shelves cabinets tables chairs sofas carpets curtains blinds plants flowers people pets lamps ceiling lights wall lights led strips spotlights pendant lights extra windows extra doors extra beams extra columns extra glass wall decorations textures not present in the reference any objects whatsoever do not change camera angle perspective composition room geometry staircase geometry steel structure geometry railing layout window position radiator position wooden floor direction mezzanine geometry wooden underside of the mezzanine wall color any proportions any material assignments described above if the model is uncertain it must leave the scene empty rather than adding anything 9 final output final image should be ultra realistic clean technically believable empty client ready high resolution faithful to the png reference image corrected only by the addition of the white sloped ceiling target look 8k high end architectural render quality
