To do so, start the Photos app and open a previously altered photo in full-screen mode. Then, in the top-right area, press the three-dot menu and choose Copy Edits. This option will display only if the picture was modified in Photos rather than a third-party photo editor. Finally, go to the picture you want to copy the modifications to, touch the three-dot menu, and then choose Paste Edits. After a few seconds, the picture modifications should display.
