# Automatic gravity crop

Chooses the most important image features and objects and sets the focal point on them when cropping.

<mark style="color:orange;">**gravity=smart**</mark>

<mark style="color:orange;">**gravity=auto**</mark>

<mark style="color:orange;">**gravity=face**</mark>

## Smart gravity

Sets the crop focal point on the people in the image or on the most prominent features if no faces are detected. Useful for creating thumbnails from images with different aspect ratios.

## Automatic gravity

Setting the **gravity** parameter to **auto** finds the focal point of the image based on entropy.

## Face gravity

When using **gravity=face**, all images with one dominant face are focused on this face upon cropping. If there are many or no faces in the image, **gravity** falls back to **auto**.

{% hint style="info" %}
If you would like to try and include multiple faces in the image, you can use **gravity=smart**
{% endhint %}
