# Flow-Field Line Image

> Many fine lines bend through a coherent directional field, using density and color to reveal flowing forms.

## About this style

Flow-field imagery sends fine lines through a coherent directional field. They curve around boundaries and gather in dark regions. The same line system carries both tone and movement, allowing the source forms to emerge from density and turning rather than a photograph beneath a line overlay.

A flow field assigns local directions that guide continuous paths.

Lines curving around a nose and gathering in hair can make a face emerge from their movement and density.

### How the style changes different subjects

- **Portrait**: Turning, widening or rising lines make facial features emerge from a continuous field.

- **Landscape**: Ordered line groups describe scenery through direction and density.

- **Object**: Bent lines or peaks replace literal texture and describe object curvature.

**Subjects**: Choose side-lit portraits, terrain, streamlined objects or waves with strong contours anchoring the line field.

## Reusable style prompt

```text
Rebuild the image from thousands of fine streamlines moving through one coherent smooth flow field. Let the lines curve along major contours and turn around structural boundaries, gathering densely in dark regions and opening into visible background in highlights. Derive a restrained line palette from the source colors and vary length subtly without breaking the overall flow. Preserve recognizable forms through density and directional organization. Keep a flat drawn finish, without broad three-dimensional ribbons, random hair tangles, arrows or an underlying photograph.
```
