## Custom test prompt

```
Imagine a soft, evenly-lit portrait of a 50-year-old woman with silver-streaked dark hair, a slight smile, photographed straight-on at eye level. Now generate the same portrait with an intense chiaroscuro effect. The woman should retain her original features and expression. Introduce harsh, directional light, appearing to come from above and slightly to the left, casting deep, defined shadows across the face. Only slivers of light illuminating her eyes and cheekbones, the rest of the face is in deep shadow.
