# AVCaptureManualExposureBracketedStillImageSettings

A configuration for defining bracketed photo captures in terms of specific exposure and ISO values.

```
class AVCaptureManualExposureBracketedStillImageSettings
```

## Overview

The `AVCaptureManualExposureBracketedStillImageSettings` class is a concrete subclass of the `AVCaptureBracketedStillImageSettings` class used when bracketing exposure duration and ISO.

An `AVCaptureManualExposureBracketedStillImageSettings` instance defines exposure duration and ISO settings that should be applied to one image in a bracket. An array of `AVCaptureManualExposureBracketedStillImageSettings` objects is passed to `captureStillImageBracketAsynchronouslyFromConnection:withSettingsArray:completionHandler:` to specify the bracketing.

You can query the minimum and maximum duration and ISO properties of the [`AVCaptureDevice`](/documentation/AVFoundation/AVCaptureDevice) instance supplying data to an [`AVCaptureStillImageOutput`](/documentation/AVFoundation/AVCaptureStillImageOutput) instance. If you wish to leave [`exposureDuration`](/documentation/AVFoundation/AVCaptureManualExposureBracketedStillImageSettings/exposureDuration) unchanged for this bracketed still image, you pass the value `AVCaptureExposureDurationCurrent` when creating the instance. To keep the ISO unchanged, you pass `AVCaptureISOCurrent` when creating the instance.

## Topics

### Creating a manual bracketed exposure settings instance

[`+  manualExposureSettingsWithExposureDuration:ISO:`](/documentation/AVFoundation/AVCaptureManualExposureBracketedStillImageSettings/manualExposureSettings(exposureDuration:iso:))

Creates a configuration of still image settings using the specified exposure duration and ISO.

### Getting manual exposure setting values

[`ISO`](/documentation/AVFoundation/AVCaptureManualExposureBracketedStillImageSettings/iso)

The ISO for the still image.

[`exposureDuration`](/documentation/AVFoundation/AVCaptureManualExposureBracketedStillImageSettings/exposureDuration)

The exposure duration for the still image.
