# Spherical Bulge Warp

> A central region swells outward and magnifies, smoothly reconnecting with the surrounding image.

## About this style

Spherical bulge expands one circular region outward, bending nearby structure around an implied convex surface. The distortion fades smoothly at its boundary, leaving the surrounding image as a stable reference.

Spherical bulge enlarges a local center and blends back toward an unchanged boundary.

Curved tile joints within a rounded patch, surrounded by straight ones, make the image seem swollen locally.

### How the style changes different subjects

- **Portrait**: Central features contract or enlarge, changing expression while the periphery remains steadier.

- **Landscape**: Local circular deformation bends scenery into a center-periphery scale contrast.

- **Object**: An object's center pinches or bulges, bending nearby edges while largely retaining position.

**Subjects**: Choose round objects, flowers, geometric buildings or intentionally exaggerated portraits, centering the change on the intended emphasis.

## Reusable style prompt

```text
Apply a local spherical bulge warp to one central circular region. Magnify and expand geometry within the bulge, curve straight features around the implied convex surface, and blend displacement smoothly back to zero at its outer boundary. Preserve the continuous image colors and recognizable content outside the affected region. The effect is coordinate distortion rather than a new glass orb or physical sphere. Avoid full-frame fisheye projection, inward pinching, spiral rotation or added reflective material.
