Noise

Noise post-processing: fine film grain over a 3D scene that takes the digital edge off clean renders and gives an analogue feel.

Settings and defaults

Intensity
0.5

Noise lays a fine grain over the whole picture, like film grain or the noise of a camera shooting in low light. Clean 3D renders can look too perfect; a little grain breaks up smooth surfaces and gradients, takes the digital edge off and makes a scene feel shot rather than computed.

How it works

A layer of random grain is blended over the finished frame with a colour-dodge blend, so it brightens rather than darkens: it shows most in the mid-tones and highlights and leaves deep blacks close to black.

Settings

  • Intensity: how visible the grain is. The presets use very low values, a few percent, for a film feel; higher values give a gritty, found-footage look.

Use it for

Cinematic heroes, where the Cinematic preset adds light grain to depth of field, bloom and a vignette. Retro and vintage looks, where the Retro preset combines it with Sepia and a heavy vignette. Smooth gradient backgrounds and skies, which grain helps keep from showing visible steps. Editorial pages that want a printed, analogue texture, alongside the Engraving or Relief image objects. Grain is easy to overdo: set it so you notice it is gone when you switch it off, not so you notice it while it is on.
