# Sharpen Tool

The **Sharpen** tool in Aperty is designed to enhance the clarity and definition of your portrait by adjusting how sharp the facial features and textures appear.

Each slider gives you precise control over different aspects of the sharpening process.

* **Sharpen**: This slider increases the sharpness by intensifying the contrast around the edges, such as the eyes, lips, and jawline. Raising this value makes these features stand out more, creating a crisp, well-defined look. Lowering the slider softens the image, reducing definition, which can be useful if you aim for a smoother, more delicate portrait. Overuse of sharpening, however, may cause the image to look harsh or unnatural, so finding a balanced setting is important.
* **Radius**: Controls how wide or narrow the sharpening effect spreads around the edges. A smaller radius focuses on finer details, such as eyelashes, strands of hair, or subtle facial lines, providing a sharp and detailed appearance in those areas. A larger radius affects broader regions, like the overall contours of the face, jawline, or cheekbones. The radius helps you control whether the sharpening enhances just small details or the overall structure of the face, giving you flexibility based on the portrait's needs.
* **Preserve Textures**: This slider ensures that the sharpening effect enhances edges without disrupting the skin's natural texture. It prevents the skin from becoming overly smoothed or too harsh, which can often happen with excessive sharpening. By increasing this value, you retain the realistic texture of the skin, such as pores and soft gradients, ensuring that the portrait looks polished yet natural.

{% hint style="info" %}
For a balanced portrait, use a moderate Sharpen setting with a smaller Radius to emphasize details like eyes and hair. Combine this with a higher Preserve Textures setting to keep the skin natural and smooth while achieving a sharp and polished overall effect.
