Hi rocknromp,
I understand that an apparition is appearing in your photos when using your iPhone's rear-facing camera. Fortunately, though, the steps outlined below can help rid your iPhone's camera of this shadowy figure and get you back to taking great photos again.
- Make sure that there’s nothing blocking the camera lens. If you’re using a case, try removing it.
- Force the app to close, then open the Camera app again.
- Restart your device, then open the Camera app again.
- Make sure that the camera lens is clean. If you need to clean the lens, use a microfiber cloth. If you see dirt or debris inside the lens, take your device to an Apple Retail Store or Authorized Service Provider for more help.
- With iPhone 6 Plus and iPhone 6s Plus, a metallic case or magnetic lens could interfere with optical image stabilization. Try taking a picture without it, then compare the quality.
- Adjust the focus by tapping on the person or object in the preview screen. You’ll see the screen pulse or briefly go in and out of focus as the camera adjusts. In photo mode, try to stay steady when adjusting the focus. If you move too far in any direction, the camera will automatically refocus to the center. In video mode, you can adjust the focus before you begin recording.
If you still have issues with the focus on your camera, contact Apple Support.
