What you want to ask is why the photo of Apple's mobile phone was edited, and why did it change from one to two? It may be caused by camera settings or iCloud.

The solution to this problem is as follows:

First, turn off the HDR function:

If you are not using the iPhone 1 1 series and iPhone SE 2 models, you can choose to keep the "normal exposure photos" on the iPhone. When this setting is turned on, iPhone will keep two photos. If you don't need this function, you can go to iPhone Settings-Camera and turn off the "Keep photos exposed normally" function.

Second, close iCloud photos:

1. When you open iCloud photos, iPhone will automatically upload all photos and videos and store them in iCloud, so you can view them on any device. If you have the problem of duplicate photos, you can turn off the photo options in iPhone settings-"Apple ID"-"I cloud" and turn off the cloud disk function of iCloud to see if it can return to normal.

2. It should be noted that when these options are turned off, photos and data in the iPhone will not be saved to iCloud synchronously. You can use AISI Assistant to export photos for backup, or fully back up iPhone data.

Third, log out of Apple ID and log in again:

1. If logging out of iCloud still doesn't solve the problem, please try logging out of your Apple ID, open the Apple ID settings, and click "Log out". At this point, you will be prompted to enter the password. Please do this. Then you will be asked if you quit. In this step, you can click "Cancel" first, and then return to the album to see if there are any duplicate photos.

2. If you still see duplicate photos after returning, please try to log out of Apple ID completely, and then log in again to see if it is normal.

If none of the above methods can solve your problem, you can consider updating the system to the latest version.
