## Topics

### Creating a tone mapping component

[`init(exposure:toeStrength:toeLength:shoulderStrength:shoulderLength:shoulderAngle:)`](/documentation/RealityKit/ToneMappingComponent/init(exposure:toeStrength:toeLength:shoulderStrength:shoulderLength:shoulderAngle:))

Initializes a `ToneMappingComponent` with the specified parameters. Values outside of their respective ranges are clamped.

### Configuring the tone curve

[`exposure`](/documentation/RealityKit/ToneMappingComponent/exposure)

In F-stops

[`toeStrength`](/documentation/RealityKit/ToneMappingComponent/toeStrength)

As a ratio, clamped to [0.0, 1.0]

[`toeLength`](/documentation/RealityKit/ToneMappingComponent/toeLength)

As a ratio, clamped to [0.0, 1.0], where 1.0 means 50% of white point

[`shoulderStrength`](/documentation/RealityKit/ToneMappingComponent/shoulderStrength)

In Fstops, clamped to [0.0, 10.0]

[`shoulderLength`](/documentation/RealityKit/ToneMappingComponent/shoulderLength)

As a ratio, clamped to [0.0, 1.0]

[`shoulderAngle`](/documentation/RealityKit/ToneMappingComponent/shoulderAngle)

As a ratio, clamped to [0.0, 1.0]
