Ys2

Just by tapping on the screen, you can leave the person you're taking a picture with as if you're copying them.
With Ys2, you can make cool videos just by shooting them , whereas in the past they were complicated and tedious to edit.
For example, two people chasing each other. If you take a picture of a person walking in front of you, your alter ego will be left behind one after another, and your surroundings will be recognized by AR, so if you turn around, your alter ego will be left behind.
You can make a video of your alter ego that you have placed in advance, or you can make a video of your shadow alter ego by turning around the person taking the photo.

The tip is to walk around first and let your iPhone know what's going on around you.
