# moireReductionAmount

A value that indicates the amount of moire artifact reduction to apply to high frequency areas of the image.

## Declaration

```swift
var moireReductionAmount: Float { get set }
```

## Discussion

Discussion The value should be in the range of 0...1. The default value varies by image. A value of 0 indicates no moire reduction, and a value of 1 indicates maximum moire reduction. note: The isMoireReductionSupported property is false if the current image doesn’t support this adjustment.
