# Film Grain
Learn how to add a classic analog look to your photos with Aperty’s Film Grain tool. Control intensity and texture to suit your creative vision.
The **Film Grain** tool in Aperty adds a textured, grainy effect to your portrait, mimicking the look of traditional film photography. This tool is perfect for adding a vintage or artistic feel to your images while allowing you to control the intensity and appearance of the grain.
* **Amount**: Controls the overall visibility of the grain effect. Increasing the slider adds more pronounced grain while lowering it makes the effect more subtle. Use this to balance between a fine or strong grain overlay, depending on the desired look.
* **Size**: Adjusts the size of the grain particles. Higher values result in larger, more noticeable grain, creating a rough, gritty feel. Lower values produce finer, more delicate grain, perfect for subtle texture enhancement.
* **Roundness**: Modifies the shape of the grain particles. Increasing the roundness makes the grain appear smoother and more circular, while lowering the value makes the grain more irregular and sharp-edged, contributing to a rougher, more textured look.
{% hint style="info" %}
For a classic film effect, use a moderate Amount with a smaller Size and high Roundness to create fine, soft grain. For a bolder, more dramatic look, increase both Size and Amount and experiment with lower Roundness to add a raw, textured feel to your portrait.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://support.aperty.ai/how-to-use-aperty/four-key-tools-categories/creative-tools/film-grain.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
