With the Free Rotate Layer and Free
Rotate Selection commands, you can rotate an item by any amount.
Use the Free Rotate Layer command to straighten image, and
click the Commit button to apply the rotation.
Select the layer or selection you want to rotate.
Choose Image > Rotate > Free
Rotate Layer or Selection. A bounding box appears in the image.
Note: If you select an image that is a Background layer (such
as a photo imported from a camera or scanner), you are given the
option of turning it into a regular layer so that you can transform
it.
(Optional) To change the point around which the item
rotates, click a square on the reference point locator in
the options bar.

Click and drag the rotate handle at the
bottom of the bounding box. The cursor will change to concentric arrows when
it’s hovering over the handle. To constrain the rotation to 15°
increments, hold down Shift as you drag.
Type an angle of rotation between ‑180 (maximum counterclockwise
rotation) and 180 (maximum clockwise rotation) in the Rotate text
box of the options bar.
Do one of the following:
To apply the transformation, double-click inside
the bounding box, click the Commit button , or
press Enter.
To cancel the transformation, click the Cancel button , or
press Esc.
