enhance realism only do not change any materials colors or shapes goal make the entire image more photorealistic while keeping every material texture color object lighting direction and geometry exactly the same only improve realism clarity sharpness reflections and material fidelity realism improvements increase physical accuracy of all existing textures without altering them enhance micro details on stone plaster wood metal and glass improve surface roughness and subtle bump normal information strengthen natural lighting behavior while keeping the same brightness and direction improve global illumination and contact shadows very soft and natural glass reflections make all reflections more physically accurate reflect the real surroundings that are already present in the image no mirror effect keep reflections natural balanced and realistic materials do not replace any material do not change colors do not add new patterns simply refine the existing textures increase their realism add soft micro variation consistent with the original appearance lighting keep the same lighting setup exactly make the light more natural clean and physically correct avoid harsh contrast add soft ambient light and subtle bounce light for realism sharpness depth improve depth clarity and overall crispness strengthen realism while maintaining the original composition and atmosphere restrictions do not change geometry layout materials textures only improve realism colors camera angle object placement landscaping sky shadows shape or direction only enhance realism sharpness reflections textures and lighting quality
