Acid

Background

This entry is a dye-broken, edge-eaten bad color-print look—not a rainbow filter.

Narrative function

Acid shapes how audiences read space, time, power, or emotion. Used with intention, it becomes part of the film's visual grammar rather than decoration.

How it works

Execute Acid with clear marks: lock lens, distance, lighting, and timing so the technique supports the beat. Rehearse once, then protect continuity across coverage.

When to use

• When the scene's emotion or geography benefits from Acid.
• When you want a readable visual motif that can pay off later.
• When a contrasting setup will make the next cut or reveal land harder.

16:9 cinematic demo: Acid.
Technique: This named look imitates chemically or environmentally damaged color print, with unstable dyes and distressed boundaries rather than a cheerful rainbow grade.
Scene: A retired radio host folds a yellow station map inside a deserted cable-car booth.
Start: Eye-height waist-up frame; face left of center, map across the bottom, rain-stained window behind.
Motion: The host folds once between seconds two and five. Keep the face's contour stable while magenta-yellow dye damage creeps inward from the top edge and stops short of the eyes.
End: The folded map is held to the chest; the damaged print border remains visibly separate from the physical booth.
Camera: 50 mm rectilinear prime; fixed focal length, f/4, shutter 1/48s, ISO 400, 24fps.
Light: A broad 5600 K window at camera left supplies the key; a white floor returns weak fill. Keep the opposite wall dark and retain texture in pale surfaces. Lock exposure and white balance rather than letting the effect drive automatic corrections.
Color: Overheated yellow and magenta patches against faded brown; localized dirty whites and black dye loss. Preserve distinct shadow, midtone and highlight values within this palette; keep the named material treatment consistent between frames, with controlled highlights rather than a generic photographic filter.
Duration: 8s. Mode: composite.
