Film Grain Emulation, Blender Compositor Node.

I made a PBR Film Grain Compositor Node. I tried to get it as accurate as possible without using FotoScans. It can simulate almost all characteristics of film. ISO-dependent grain, which blends correctly with the original image. Subtle softening and bleed from the 3 layers of the Halide Emulsion, which have their own noise map. The node is also animated, so the noise is different every frame.
