Hello everyone. So up to now I've been experimenting with using grain and texture to add some grit to my art and I've been streamlining rendering by combining passes that go from dark to light values for diffusion, and light to dark values for occlusion. I've been adding surface anisotropy by brushing light colors over surfaces and layering it with grain and different textures to enhance the effect of visual snow. procedural noise doesn't come close to this effect because the rods and cones in our eyes do not create a grid-like noise. I think grunge textures simply look better and add more variability to surfaces. I exported a video timelapse to show the process. With a single light source its easier to establish values in black and white and use gradient maps or layers to add color. This is an affront to color theorists, but the point is to enhance the drama in a chiaroscuro painting by using colorful noise.
