The minimum exposure bias in EV units that this range supports.

[`maxExposureBias`](/documentation/AVFoundation/AVExposureBiasRange/maxExposureBias)

The maximum exposure bias in EV units that this range supports.

[`containsExposureBias:`](/documentation/AVFoundation/AVExposureBiasRange/containsExposureBias:)
