Galaxy Note 8: Dual Camera > How to take portraits using Live focus feature?

The Live focus feature allows the camera to capture the subject and the background separately so that you can get an out-of-focus photo with the focus on the subject. Adjust the background blur effect on the preview screen and take a photo that highlights the subject. This feature is recommended that you position subjects about 1.2 m away from the camera lens. Position the subject that you want to focus on close to the device. Also, use this feature in a place that has sufficient light.
