enhance the realism of the cgi render while keeping the original proportions textures colours and design exactly the same improve realism through physically accurate lighting global illumination natural shadows and realistic reflections introduce subtle environmental effects such as ambient occlusion light bounce and depth of field simulate real world camera behaviour including lens imperfections slight motion blur where appropriate and natural exposure add micro details like subtle surface irregularities tiny lighting variations and realistic shading to remove the overly perfect cgi look maintain the exact geometry and materials while making the scene appear naturally photographed rather than digitally rendered
