An iPhone capturing a woman in front of two mirrors mistook her for multiple people, resulting in her pose showing three different arm positions in one photo.
Engadget reports that Instagram user Wheatpraylove posted about the oddity after trying out wedding dresses at a bridal shop.
“I went wedding dress shopping and the fabric of reality crumbled,” she posted. “This is a real photo, not photoshopped, not a pano, not a Live Photo.”
In a Highlights Reel explaining the issue, she said that employees at her local Apple Store explained it was because the iPhone actually captured multiple images in one shot to get the best possible picture throughout an entire scene.
The image resulted from the iPhone stitching the best parts of two photos together, with the left half of the image being the first and the right half the second.

If one were to cut the image in half, the left side with the reflection of her initial pose would make sense on its own, while the same goes for the right part, which shows her final position.
If the iPhone detected she was standing in front of a mirror or if she had stood completely still at the exact moment the photo was taken, the anomaly would not have occurred.
Instead, her quick movement right at the time of the capture resulted in the camera’s software detecting her reflections as two additional people.
The iPhone is not the only smartphone that uses software to stitch multiple images together for one final best shot, but it is unclear whether users of other phones that use similar technology could get comparable results.
