Oct 25, 2018 - With the new iPhone XS, XS Max and XR, iOS 12 invokes both lenses in Portrait mode to change the depth of field after the photo is taken.
Note:. To create an image that has wider depth of field (more area in front of and behind the subject that is in focus) use high fStop values, such as f16, f22, f32. To achieve narrow depth of field (less area in front and behind the subject that is in focus) use low fStop values such as f2.8, f4 or f5.6. For more information on fStops, see. Depending on the fStop and Focus Region Scale values, parts of the object may or may not be in focus. To ensure the center of an object is in focus for Depth of Field. Select the object in the view.
Make sure Object Details is turned on in the Heads Up Display menu. ( Object Details is on by default).
Notice the Distance from Camera value. Use the Distance from Camera value as the Focus Distance value in the Depth of Field section for the current Camera.
