use the provided photorealistic render strictly as the base image maintain the exact composition camera angle lighting balance materials and all existing elements unless explicitly modified below task improve integration of the added lamp back right corner seamlessly integrate the existing inserted lamp located in the back right corner of the scene do not change the position size or design of the lamp only improve its realism and blending into the scene ensure physically accurate contact shadows where the lamp meets the floor and wall match the lamp s materials reflections and surface roughness to the scene s lighting conditions adjust color temperature and light intensity so the lamp emits a soft warm and subtle glow no overexposure the light should gently illuminate nearby surfaces wall floor surrounding objects with realistic falloff eliminate any visible compositing artifacts cutout edges mismatched noise sharp borders important constraints do not add any new objects do not modify any other furniture walls textures or lighting setup in the scene do not change global exposure or overall scene mood only locally adjust the lamp s contribution preserve the original render exactly outside of the lamp integration goal the lamp should look naturally part of the original render with believable lighting and subtle presence
