问题描述:

AVFoundation brightness/exposure is different than the native camera. Is it possible to replicate the native camera settings with the AVFoundation framework?

网友答案:

If you're looking for auto-exposure, set a key-value observer for "adjustingExposure" and set the exposure mode to AVCaptureExposureModeContinuousAutoExposure. If you're trying to implement manual exposure, have a look at this WWDC session on camera controls.
