Ultra realistic interior photography, vertical 4:5 composition. Contemporary collector's residence with chalk-white plaster walls, pale greige architectural surfaces, light travertine flooring, oyster-white linen sofa, soft pearl-gray accents and subtle black details. A single 4:5 artwork mounted on the main wall. Exact 4:5 canvas ratio. Standard 100x125 cm proportions. The artwork is the visual focal point of the room. Bright but soft daylight. Airy atmosphere. Refined neutral palette dominated by whites, ivory, chalk, oyster, pale greige and light stone gray. Avoid terracotta, avoid camel tones, avoid orange undertones, avoid yellow walls, avoid dark brown interiors, avoid earthy saturation.
