create a high end photorealistic architectural interior visualization based exactly on the provided reference image the image shows an existing apartment interior with a newly inserted steel mezzanine gallery structure a wooden staircase black metal railings warm wooden floors and light plaster walls the goal is to transform the current technical sketchup like model into a realistic client presentation render while preserving the original design and construction exactly 1 strict geometry lock critical preserve 100 exactly original camera angle original perspective original field of view original composition all room proportions wall positions ceiling height impression floor level mezzanine gallery position mezzanine thickness all steel beam positions all steel beam dimensions and orientation vertical steel column position height thickness and proportions staircase position angle width and number of steps railing position height and rhythm door position and size left wall position rear wall position right wall position wooden floor direction and layout this is a technical architectural render not a redesign do not change the structure do not move the steel column do not reduce or enlarge any beam do not simplify the steel construction do not redesign the stairs do not change the railing geometry do not add or remove any structural element the final result must look like a realistic version of the same exact proposed steel construction 2 scene description interior view of a renovated apartment with a newly inserted steel load bearing mezzanine structure the scene contains large dark steel beams forming the main support structure of the mezzanine one dominant rectangular dark steel column on the right side near the staircase a warm timber underside of the mezzanine deck black metal railing with vertical balusters on the upper gallery black metal railing following the staircase wooden staircase with warm natural wooden treads warm wooden plank flooring on the ground floor light off white plaster walls simple white interior door in the back wall clean architectural space without furniture the interior should feel realistic structurally credible clean and suitable for presentation to a client before realization 3 material specification steel structure render the steel beams and column as dark anthracite black steel matte to satin surface finish realistic powder coated structural steel subtle surface unevenness physically correct roughness very soft edge highlights realistic contact shadows where steel meets wood and walls no excessive shine no chrome effect no rusty industrial look the steel must look solid heavy load bearing and technically believable wood render all wooden surfaces as warm natural wood realistic grain satin finish visible plank direction subtle variation between boards natural tone not orange not yellow believable floor reflections realistic stair tread thickness wooden areas include ground floor planks staircase treads underside visible timber layer of the mezzanine upper gallery timber edge walls render walls as light off white plaster subtle fine texture clean but not sterile realistic wall imperfections only very slightly visible no decorative wallpaper no added panels no strong color change railings render railings as black painted metal slim vertical balusters matte finish crisp edges same position and rhythm as in the reference no glass railing no decorative railing no redesign door render the rear door as simple white interior door clean painted finish subtle panel lines small metal handle realistic scale and position 4 lighting use soft natural daylight lighting should be realistic neutral slightly warm but not yellow evenly balanced coming mainly from the open interior space existing daylight direction soft shadows under the gallery visible but not dramatic ambient occlusion around steel beams and column good readability of the steel structure natural brightness on plaster walls do not create dramatic cinematic lighting do not add visible lamps do not add led strips do not add spotlights do not create evening or night mood do not overexpose the image the render should look like a clean daytime architectural visualization 5 photorealism boost upgrade the image from a basic 3d model to a professional photorealistic render with physically based materials realistic global illumination accurate contact shadows realistic ambient occlusion believable steel roughness natural wood grain subtle material variation sharp but not artificial edges realistic wall texture correct scale perception photographic exposure natural contrast realistic shadow depth below the mezzanine subtle 1 2 photographic grain to remove cgi plasticity the image must look like a realistic architectural visualization for client approval not an artistic reinterpretation 6 absolute negative prompt do not add furniture sofa table chairs kitchen lamps pendant lights led strips plants flowers decoration paintings curtains carpets people pets extra doors extra windows new ceiling design wall panels brick wall concrete wall luxury accessories industrial decorative elements do not change steel beam position steel beam size steel beam number steel column position steel column size staircase geometry railing layout mezzanine outline wall positions door position floor direction camera angle perspective composition avoid over stylized industrial look rusty metal glossy black metal exaggerated reflections yellow lighting overly dark shadows unrealistic wood texture cgi plastic appearance architectural redesign 7 final output final image should be ultra realistic clean technically believable client ready high resolution professional architectural visualization faithful to the provided reference image suitable for presentation of the proposed steel mezzanine structure target look 8k high end architectural render quality
