## Discussion

When you edit an asset, you have the option of resuming the most recent edit made. This process uses a [`PHAdjustmentData`](/documentation/Photos/PHAdjustmentData) object to describe the edit, and an extra copy of the photo data representing the state of the asset before the edit. For details, see [`PHAsset`](/documentation/Photos/PHAsset).
