# Lens Correction

Fotello automatically applies lens correction to keep lines straight and edges clean. With so many new lens models coming to market, a few can occasionally get missed from our current correction database.

### If you're noticing

* Barrel distortion (edges bulge outward)
* Fisheye / ultra-wide stretch
* Vignetting (dark corners)

{% hint style="warning" %}
Avoid exports or pre-processing that strip EXIF metadata.

Upload the original RAWs/JPEGs straight from camera.

See: [Adding Photos](/photos/editing/adding-photos.md)
{% endhint %}

### Report a lens issue

We want to support every photographer and every setup, and that includes *your gear*. If you’re seeing distortion, please take a minute to tell us what lens you're using: [Submit Your Lens Info Here](https://forms.gle/gxdU64ZSinRZ6jtJ8)

Once we have it, we’ll prioritize adding support for your lens in our next AI model update.

{% hint style="info" %}
If you need a one-off fix right now, request a manual polish via [Human Revisions](/photos/personalizing-photos/human-revisions.md)

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://uni.fotello.co/troubleshooting/lens-correction.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
