There is a camera model in the photo properties taken by Iphone. How did it happen?

It's all normal shots. This is called EXIF information. You can look at the picture on the computer with the software, and you can see it in the properties.

Obviously, your photo has been processed, and EXIF information was deleted when you saved it. If it is copied directly from the mobile phone, this information must be available.

Set the photo in the camera to a maximum of 8 million pixels, otherwise the phone will cut the photo. After cutting and saving, EXIF information will disappear. That is to take the same photo as 3264*2448.
