Underwater: Lane Four

Model

Prompt

SUBJECT — The person is exactly the person in the reference character sheet (Image 1): same face, skin tone, hair, build, age. Identity is locked; the sheet's grey background and multiple views are identity reference only. They wear plain dark swimwear, hair loose so the water lifts and fans it; face, hair and build stay from the sheet.

SCENE — A public swimming pool, lane 4. They stay wholly below the surface, head to feet inside the frame, suspended in open water, clear water all the way to the viewer. At 7.0s they are 1.1m away, level with the face, arms at shoulder height, eyes to camera, mid-exhale, bubbles rising past them.

LOOK LOCK — Sun through the surface, hard but broken, 75° top-down, dragging a moving caustic net across face, shoulders and floor at once; a warm low light camera-left restores skin colour. Palette: pool cyan, caustic white, warm skin, grout grey.

CAMERA — A wide 20mm view held in the water beside them, drifting two centimetres as the water moves. Three moves in order: the view rises, closes in, then arcs camera-left. They begin small with the floor far below and end large and close, the floor swinging behind them.

BEATS (8.0s, one continuous take)

0.0-3.0 The view rises. They hang full-length, arms wide, a slow scissor kick, hair lifting late and moving after the head stops. Bubbles rise around them; caustics crawl on shoulders and floor together.

3.0-5.5 The view closes from 1.8m to 1.1m and they grow in frame. Hair fans forward and keeps drifting after the movement ends; a second exhale sends bubbles up the sun shafts.

5.5-7.0 The view arcs 18° camera-left as they rotate to hold the face to camera. Bubbles rise, hair drifts, caustics move over cheek and floor together.

7.0-8.0 The arc continues to 25° and keeps easing. Nothing rests: hair drifts, the body rises a little, bubbles climb, caustics crawl on face and floor through the final frame.

AUDIO — Underwater: muffled pool ambience, water moving, bubbles.

FRAME INVENTORY — The person, rising bubbles, blue water, the tiled floor and grout grid, a lane rope, sun shafts and caustics. Open water fills all space between viewer and subject. The frame is complete with those elements alone.

LOCK RESTATE — Caustics move independently across both the person and the floor at every moment, because static light reads as a dry set; everything drifts and nothing settles, hair, limbs, body and bubbles still moving on the last frame.
