- **Manual:** This mode lets you set the exposure value manually.
- **Automatic**: `Highlights`, `Balanced`, and `Shadows` automatically adjust exposure according to the surrounding lighting.
- `Highlights`- optimizes the exposure to capture bright areas in the environment, while potentially underexposing dark areas.
- `Balanced` - optimizes the exposure to capture brighter and darker areas in the environment equally.
- `Shadows` - optimizes the exposure to capture darker areas in the environment, while potentially overexposing bright areas.

::: tip
The mode you choose should depend on the environment. The images below provide an example and some caveats.

## Manual Exposure Mode

`Manual` mode allows you to set the exposure time between 1 ms and 1000 ms.

::: tip
**Note:** Exposure duration is inversely related to camera frame rate. Exposure values above 330 ms will reduce the scene camera rate below 30fps.
