# DetectFaceCaptureQualityRequest

A request that produces a floating-point number that represents the capture quality of a face in a photo.

## Declaration

```swift
struct DetectFaceCaptureQualityRequest
```

## Overview

Overview This request produces a collection of FaceObservation objects with the property captureQuality set to a value ranging from 0 to 1. Faces with quality closer to 1 are better lit, sharper, and more centrally positioned than faces with quality closer to 0. If you don’t execute the request, or the request fails, the property captureQuality is nil.
