A starter line you can copy. The full timed recipe, still-image and production prompts are on the shot card.

Prompt rule: Stage a practical continuous near-to-far range and keep focus stable while testing all essential planes at delivery resolution; do not promise unlimited depth or hide a split-focus seam.

Deep Focus: Deep focus keeps a substantial continuous range of distances legibly sharp within one shot. Keep the subject readable; motivate camera and light.

Technique guide

When to use
Allows the audience to simultaneously observe the nearby helmet, the mid-range fire truck, and the firefighter closing the door in the distance, and follow the person's complete action along the depth direction.
How it works
Limit the main information to a practical range of 1.5 to 6 meters that can be verified, rather than placing the lens at infinite distance. Use a wider angle, appropriate aperture, and sufficient lighting to establish the range, and check the intermediate layers. Have the person move along the passage beside the fire truck without passing through the vehicle, and keep the focus from jumping back and forth on a single layer.
Common mistakes
Only two clear areas, with a noticeable break in the middle. It requires unconditional clarity from as close as 10 cm to infinity.

How to read this page

Deep Focus (Deep Depth of Field) is one technique in Focus & Depth. The definition states the single mechanism the frame has to show. The technique guide covers when to use it, the steps, the usual mistakes, how it differs from the neighbors, and what a successful take looks like.

The clip above is one reading, made with a third-party video model. Another model, or the same model on another day, can land on a different frame. It is an example, not a promise that a prompt will match it.

The free short prompt is a starter sentence. The shot card is the timed recipe: scene, start and end frames, action, light, and color. Three sample cards are free on the site. The rest are part of GrokCine Pro. A second name for the same shot keeps its own URL and points back at this definition.

When you write a prompt, keep the one mechanism in the definition, then name the subject, the motion, and why the light is there. Do not stack a neighboring technique into the same sentence. If the name or the example is wrong, send this page's URL from the contact page.

Recipe

8 seconds · single take

A small-town drama, the day the station is told it will close: at noon in the fire station, a brass-trimmed fire helmet hangs on a peg in the near foreground, a red engine gleams in the middle of the bay, and a firefighter in her thirties with rolled sleeves closes the rear bay door deep in the background; hose racks line the walkway beside the engine.
