Half your footage is wallpaper

Three jobs an image can do, and one it cannot

When a picture appears over somebody speaking, or beside a paragraph of text, it is doing one of three jobs:

1. Illustrative: it shows the thing being described. She says “the machine jams on thick denim”, you see thick denim jamming a machine.
2. Evidential: it proves something the words only claim. He says “we make four hundred a week”, you see the rack with four hundred on it.
3. Continuity: it covers a join. You have cut two sentences together that were three minutes apart, and the cutaway hides the jump.

The fourth category is wallpaper: a slow pan across a workbench, a shot of hands doing something unrelated, a stock photograph of a team smiling at a laptop. It is doing none of the three jobs. Most people’s material is largely wallpaper, and it feels productive to shoot because it is easy and looks nice.

The test

Cover the image. Read or listen to the words alone. Then cover the words and look at the image alone. If your understanding is the same in both cases as it is with both together, the image is carrying nothing.

This is a workable version of a real finding about how people take in two channels at once: pairing a picture with words helps recall when the picture adds information the words do not have, and helps very little when the picture merely restates them. Identical is not reinforcement. Identical is one channel running twice while the viewer’s attention pays for two.

The shot that contradicts is worse than none

There is an asymmetry worth knowing: when picture and voice disagree, most viewers believe the picture and rewrite the voice to fit. Say “we do everything by hand” over a shot that happens to include an industrial machine in the background and you have not told a small inconsistency, you have told the audience that the claim is untrue. They will not be able to name what bothered them afterwards; they will trust the piece less.

This is why “we’ll find something to put there” is a dangerous habit. A cutaway grabbed for its prettiness carries whatever it happens to contain, including the thing in the corner you did not notice.

Shooting so you have coverage rather than wallpaper

A reliable habit: for every idea the piece has to carry, get three shots: wide, detail, hands.

• The wide establishes where you are and how big it is.
• The detail is the thing itself, close enough to be unambiguous.
• The hands shot is a person doing the action, which supplies motion and tells you a human is involved.

Three shots per idea, ten seconds each, is thirty seconds of shooting that gives an editor real choices. An hour of drifting pans gives them none. Photographers and documentary crews have taught a version of this for decades as a five-shot sequence (hands, face, wide, over-the-shoulder, and one unusual angle) and the reason it survives is that it produces cuts that work rather than footage that exists.

Doing it for nothing

A phone shoots all of this. Lock the exposure before you start a shot, because a phone left on automatic will hunt for brightness in the middle of your take and the change is very hard to hide. Hold each shot for ten seconds even when it feels absurd; editors need handles at both ends. Shoot detail shots from about a hand’s width further back than feels right, because you cannot un-crop but you can always crop in.

For still work the same rule applies with different names. An image in a document, a slide or a post either carries information, proves a claim, or bridges a structural gap, or it is decoration, and decoration in an information-carrying piece is a cost paid in attention and load time.

The limitation

Not every piece needs to be maximally efficient. A pause, a piece of texture, a shot of the street outside, can buy the audience a moment to absorb what just happened, and a relentlessly information-dense edit is exhausting to watch. The distinction is intent: a breathing shot placed deliberately after a heavy idea is doing a job, and you can say what the job is. A breathing shot placed because the edit felt thin is wallpaper with a better explanation.
