# Film Grain

Film Grain is a effects technique: Visible photochemical texture. Reads as film rather than video, and hides the plastic smoothness generated images tend toward. In PREVIZ picking it sets the film stock in Keyframe, Director and Infinitum. It reads as nostalgic and documentary, and the library rates it basic.

What it does to the frame

Visible photochemical texture. Reads as film rather than video, and hides the plastic smoothness generated images tend toward.

- **Reads as** — Nostalgic, Documentary
- **Difficulty** — Basic
- **Runs in** — Keyframe · Director · Infinitum

The control it moves in PREVIZ

- Film stock Keyframe · Director

  Vision3 500T

  Rich, warm tones with beautiful skin rendering and fine grain. The industry standard for interior and night work.

  medium grain · ISO 500 · tungsten

  Best for: Night scenes, Interiors, Drama

Picking the technique sets these controls; it does not paste text into a prompt. The setting can be re-run, checked against the settings beside it, and carried into the next shot.

## Also in effects

The photochemical and optical textures a frame wears — grain, bloom, halation, a print process, a filter.

- **[Halation](https://aimpreviz.com/learn/techniques/halation-glow)

Intermediate · Nostalgic, Cinematic** — A red bloom around bright lights, caused by light scattering back through film stock. The signature of tungsten film shot at night.
- **[Bleach Bypass](https://aimpreviz.com/learn/techniques/bleach-bypass)

Advanced · Dramatic, Action** — Skipping the bleach step leaves silver in the print: contrast climbs, colour drains, grain hardens. Harsh and metallic.
- **[Diffusion](https://aimpreviz.com/learn/techniques/diffusion-bloom)

Basic · Romantic, Nostalgic** — A filter that lifts blacks and blooms highlights, taking the edge off digital sharpness. The standard way to soften a face.
- **[Day for Night](https://aimpreviz.com/learn/techniques/day-for-night)

Advanced · Cinematic, Horror** — Shot in daylight and graded to read as night. Sun becomes moonlight, which is why the shadows are always too crisp for real darkness.

## Reads the same way

Other techniques that read as nostalgic or documentary — a light or a lens to pair with this move.

- **[Three-Quarter Angle](https://aimpreviz.com/learn/techniques/three-quarter)

Basic · Cinematic, Documentary** — Between straight-on and profile. The default flattering angle for faces — it gives the head volume that a square-on shot loses.
- **[Medium Shot](https://aimpreviz.com/learn/techniques/medium-shot)

Basic · Documentary, Cinematic** — Waist up. Holds the figure and enough of the room to read body language — the neutral shot most scenes are built from.
- **[Steadicam Float](https://aimpreviz.com/learn/techniques/steadicam-float)

Intermediate · Cinematic, Documentary** — Smooth walking movement with none of the jitter of true handheld. Follows a subject through space without calling attention to itself.
- **[Handheld](https://aimpreviz.com/learn/techniques/handheld)

Basic · Documentary, Action** — Visible operator movement. Reads as immediate and unstaged — the reason news and vérité look the way they do.
- **[Locked Off](https://aimpreviz.com/learn/techniques/static-shot)

Basic · Artistic, Documentary** — The camera does not move at all. A deliberate choice, not an absence of one — stillness reads as composure or as unsettling patience.
- **[Golden Hour](https://aimpreviz.com/learn/techniques/golden-hour)

Basic · Romantic, Nostalgic** — The hour after sunrise or before sunset. Low, warm, and very soft — flattering to almost everything, which is why it is worth the wait.
- **[Blue Hour](https://aimpreviz.com/learn/techniques/blue-hour)

Intermediate · Nostalgic, Artistic** — The twilight window after the sun is gone but before full dark. Cool, even, and just bright enough to hold detail in the sky.
- **[Harsh Noon](https://aimpreviz.com/learn/techniques/harsh-noon)

Intermediate · Documentary, Dramatic** — Overhead midday sun. Short hard shadows and blown highlights — usually avoided, which is exactly why it reads as unglamorous and real.
- **[Practical Light](https://aimpreviz.com/learn/techniques/practical-light)

Intermediate · Cinematic, Documentary** — The scene is lit by lamps, screens and signs that are visible in the shot. Motivated light — the viewer can see where it comes from.
- **[Candlelight](https://aimpreviz.com/learn/techniques/candlelight)

Advanced · Romantic, Nostalgic** — Lit only by flame. Very warm, very soft, and falls off fast — faces glow and everything a metre away is gone.
- **[High Key](https://aimpreviz.com/learn/techniques/high-key)

Basic · Romantic, Documentary** — Bright and evenly lit with almost no shadow. The look of comedy, commercials and daytime television — nothing is hidden.
- **[Deep Focus](https://aimpreviz.com/learn/techniques/deep-focus)

Advanced · Dramatic, Documentary** — Everything from foreground to horizon is sharp. Lets action play out on several planes at once instead of directing the eye by focus.
- **[Vintage Glass](https://aimpreviz.com/learn/techniques/vintage-glass)

Intermediate · Nostalgic, Romantic** — Older uncoated lenses: lower contrast, swirling backgrounds and flares that bloom easily. Imperfection used deliberately.
