Why does the iPhone show two moons in the photo?

The phenomenon of two moons appearing when taking pictures of the moon with an Apple mobile phone is due to the reflection of the lens of the mobile phone lens module, which causes ghosting.

When reflection occurs on the surface of the lens, surrounding light will be reflected into the interior of the lens, forming a false moon image. This phenomenon is called ghosting in photography. Light interference is also one of the reasons why multiple moon images appear. When shooting, if there are strong light sources or reflective objects in the surrounding environment, light will enter the lens and cause interference, resulting in double or multiple images of the moon image.

In order to avoid this phenomenon, you can try to adjust the shooting angle or position to avoid shooting directly against the light source. In addition, using a visor or other auxiliary equipment can help reduce light interference and improve shooting quality. It should be noted that this phenomenon does not only occur on Apple phones, other phones may also experience similar optical phenomena under similar conditions. This is due to the optical characteristics of the lens itself, rather than a problem with the shooting technique.

The steps to take a clear picture of the moon with an Apple phone are as follows:

Operating environment: iPhone12, iOS14.4.1 system, etc.

1. Open the phone camera application.

2. Find the video recording option above the camera interface and select the highest quality setting, such as 4K/60fps. This ensures clearer and smoother footage.

3. Switch to the maximum zoom number supported by the phone. Use gestures or the zoom button on the camera interface to adjust the focus to the maximum to better capture the details of the moon.

4. Focus on the moon and lower the exposure. Touch the moon image on the screen to focus the camera on the moon. Then, adjust the exposure lower by sliding the on-screen brightness adjuster or exposure compensation button to avoid overexposing the moon.

5. Click the record button to start recording the video. Keep your phone steady and try to avoid shaking to get a clear video picture.

6. Finally, while recording the video, click the photo button next to the record button to capture high-quality still photos during the recording process.
