While the iPhone, iPod touch, and iPad generally do a good job of rotating images to their proper orientation, every once in a while an odd grip or shot will confound it, leaving you with some work to do before it’s ready to share or archive. Luckily, there’s an easy—and built-in—way to fix this.
Simply select the photo you need to fix, tap the Edit button, and tap the rotate button—it’s the one that looks like an arrow pointing backwards. Do this as many times as necessary to get the look you want, then tap Save.
iOS will automatically replace the original image with the new version, and you’ll be ready to use it however you please—and should you need to undo your changes, it’ll have the original waiting for you.
