Rotate or flip a photo
You can rotate your photos left and right (clockwise and counterclockwise) with the Rotate button on the toolbar of most views. You can also make a mirror image of any photo.
To rotate right, click on the Rotate button. To rotate left, press and hold the Ctrl key and then click the button. Both commands are available in the Photos menu too. Alternatively, use the following keyboard shortcuts:
rotate left: Shift+Ctrl+R or [
rotate right: Ctrl+R or ]
To create a mirror image of a photo, use the Flip Horizontally command in the Photos menu. To flip an image vertically, use the Flip Vertically command in the same menu.
If you select more than one image, you can rotate all of them at the same time.
