Prompt like a director

“I want a tense courier scene” is an intention, not a shot. Your goal is to remove four kinds of ambiguity—Subject, Setting, Light, Camera—until a crew could stage the frame without guessing.

Keep shot content separate from product settings

In the prompt	On the product controls
Subject: identity, action, state	Model
Setting: place, conditions, depth cues	Aspect ratio
Light: source, direction, color, mood	Resolution
Camera: framing, angle, lens, focus or movement	Batch and duration

A 35mm lens changes how the shot reads, so it belongs in the camera decision. A 2K export changes how the result is delivered, so it belongs on the controls.

Make the directed frame next. Once it is approved, do not describe the courier again: save that generation as an Element and cast it in later shots with @.
