create a high end photorealistic architectural interior visualization based exactly on the provided reference image preserve 100 of the following without any deviation camera angle perspective focal length field of view room proportions composition steel structure geometry exact placement and dimensions of all beams and the steel column staircase position slope and overall form railing design and location floor layout wall positions window position radiator position door position mezzanine outline and structure this is a strict preservation requirement do not redesign reinterpret or improve the architecture do not move enlarge reduce or replace any structural element do not add any new architectural features furniture decorative objects plants artworks or lighting elements the purpose is to create a realistic visual render of the exact proposed steel mezzanine construction in the existing interior scene description interior of an existing apartment space with a newly inserted steel mezzanine gallery structure the scene contains a dark steel load bearing frame forming the mezzanine perimeter one prominent vertical steel column near the staircase exposed steel beams with realistic depth and mass a mezzanine deck with warm natural wood infill timber boarding visible from below a wooden staircase on the right side leading up to the mezzanine black slender metal railings with vertical balusters around the upper level and along the staircase a warm wooden plank floor on the ground floor light off white walls with a subtle plaster texture a white door under behind the mezzanine area a window on the left side with a radiator below the overall impression should be that of a clean realistic architectural proposal technically credible elegant and materially believable material lock keep all materials faithful to the reference image and render them in a more realistic physically accurate way steel structure dark anthracite to black steel matte to satin finish realistic powder coated or protected steel appearance subtle variation in reflectivity believable edges and material depth steel column same finish as the beams solid and visually heavy realistic structural presence wooden floor warm medium tone natural wood planks visible grain realistic joints satin finish mezzanine underside timber elements warm natural wood slightly richer tone than raw pine elegant and realistic stair treads matching warm wood tone realistic thickness and texture railings black painted metal matte finish slim but solid walls soft off white plaster very subtle texture clean but not overly perfect door painted white smooth simple radiator and window details realistic but visually secondary do not change the material palette do not invent premium finishes that are not supported by the reference lighting lock use soft realistic daylight entering primarily from the left side window lighting should be natural neutral to slightly warm physically believable balanced and elegant not overexposed not too yellow not too cold add realistic global illumination and soft shadow transitions the space should feel naturally lit with good readability of the steel structure and wood textures avoid dramatic cinematic lighting avoid artificial mood lighting avoid fake sunlight streaks avoid overprocessed hdr effects realism boost push the render toward a high end client presentation level with photorealistic global illumination accurate contact shadows realistic ambient occlusion believable steel roughness and reflectivity realistic wood grain and subtle surface variation crisp edge definition subtle micro contrast in materials light natural shadowing under beams and stair elements realistic depth and volume perception soft but precise texture rendering slight photographic realism with very subtle grain noise 1 2 to avoid cgi plasticity the final image should look like a professional architectural visualization not a sketch not a concept art image and not a stylized render strict negative instructions do not change anything not explicitly requested specifically no changes to geometry no changes to proportions no changes to beam size no changes to column size or position no changes to staircase design or angle no changes to railing design no additional furniture no sofa table chairs bed kitchen lamps or decor no people no plants no curtains no extra windows no ceiling redesign no hidden structure no aesthetic reinterpretation no industrial over stylization no rustic look no luxury redesign beyond realistic material rendering no visual clutter no dramatic artistic effects output quality render as a high resolution ultra clean client ready photorealistic image suitable for presentation target quality 8k presentation quality look sharp details realistic materials balanced contrast natural color reproduction clean professional finish
