enhance only the material realism of the image focusing specifically on stone concrete and stucco surfaces the goal is to eliminate any artificial or plastic appearance and achieve true photorealistic archviz quality do not modify geometry composition or add new elements only improve material quality and realism stone critical improve the stone texture so it looks natural and physically real add subtle variation in color tone and roughness between stones avoid repetition tiling or uniform patterns ensure correct scale stones must not look too large or too small add slight depth and irregularity to joints and edges remove any flat or synthetic appearance concrete very important refine concrete surfaces to look realistic and slightly imperfect add subtle tonal variation micro stains and natural irregularities avoid perfectly smooth or uniform surfaces keep texture subtle do not exaggerate roughness ensure proper scale and no distortion or stretching stucco improve stucco so it looks matte and natural not plastic or glossy add fine microtexture and slight irregularity avoid perfectly flat or overly smooth appearance maintain clean but realistic surface variation global material rules all materials must have realistic micro detail and variation avoid uniform color and perfect surfaces avoid exaggerated textures or overly rough finishes maintain correct scale and mapping across all materials lighting interaction ensure materials react naturally to light subtle shadows and highlights should reveal texture depth avoid flat lighting that hides material detail image quality improve sharpness and clarity of textures remove blur noise and compression artifacts maintain a natural photographic look not overprocessed strict restrictions do not modify architecture layout or composition do not change positions of objects do not add or remove elements keep exact original image size framing camera and perspective final goal all materials must look real tactile and physically believable especially stone concrete and stucco no plastic no synthetic surfaces no cgi look only natural subtle high quality archviz realism
