absolutely then i d keep the rails as the only colour correction while separately instructing archsynth to make the bed softly linen and improve the natural daylight the key is to explicitly say do not alter any other existing materials or colours ultra realistic architectural render strict reference lock the uploaded image is the exact and absolute visual reference keep the entire design architecture geometry proportions layout furniture materials colours and composition exactly as shown the goal is to make the image feel more photorealistic softly illuminated and naturally lived in while making only the specific changes described below only three intentional changes 1 sliding door rails muted architectural bronze the existing sliding door rails must remain exactly the same in geometry position size and design change only their material appearance to a realistic muted architectural bronze the bronze must be deep and restrained brown bronze low saturation sophisticated and natural slightly aged brushed realistically metallic bronze must not look orange do not make the rails orange copper orange bright copper red golden yellow brass highly saturated the rails should read unmistakably as real architectural bronze with subtle metallic reflections and realistic roughness 2 bed soft natural linen transform the existing visible bedding into soft natural linen fabric while preserving the exact bed design dimensions position and overall appearance use a high quality natural linen with soft tactile texture fine subtle woven fibres relaxed natural folds slightly imperfect draping soft matte finish gentle natural wrinkles comfortable understated luxury the linen should feel light breathable soft and naturally rumpled like high quality mediterranean bedding do not make the linen shiny silky synthetic stiff heavily wrinkled or overly textured keep the existing bedding colour as close as possible to the reference unless a subtle natural linen texture requires a minimal tonal adjustment do not change the bed frame or any surrounding furniture 3 natural light from outside introduce soft realistic natural daylight entering from the existing exterior openings windows the light should feel like genuine mediterranean daylight coming from outside create soft directional daylight gentle light entering through the windows openings natural illumination on the bed and interior surfaces subtle realistic shadows soft indirect bounce light natural highlights believable variation in brightness across the room the daylight should feel warm and natural but not overly golden or orange do not add artificial light sources do not change the position size shape or design of any windows or openings do not use the lighting to artificially recolour existing materials everything else strictly locked do not change anything else in the image preserve exactly architecture geometry proportions layout camera position perspective composition existing furniture cabinetry doors windows walls plaster floors floor tiles ceiling existing beams wood elements existing colours existing material identities decorative elements do not redesign replace remove add resize reposition or reinterpret any existing element floor tile lock all existing floor tiles must remain exactly as shown do not change their colour pattern size shape orientation grout material finish layout the bathroom floor is especially locked wood lock preserve all existing wood colours and material identities exactly as shown do not darken the sliding door wood do not apply the darker ceiling beam treatment to the sliding door existing ceiling beams may retain their existing darker aged timber appearance but this must not spread to any other wooden element photorealism improve only the physical realism of the image through realistic global illumination natural daylight accurate light bounce physically plausible reflections realistic material response subtle surface imperfections natural shadows photographic depth and softness realism must not become a reason to change the design or material colours final priority reference image existing design existing materials and colours specific rail bed lighting changes photorealism when uncertain preserve the original reference only change the sliding door rails to muted architectural bronze make the bedding soft natural linen and introduce realistic natural daylight from outside everything else stays the same
