How to Use Content-Aware Crop to Rotate
If your photo isn’t perfectly straight, you can use the Content-Aware Crop tool to straighten your image, and it will automatically fill in missing area around the corners.
First, click on the Crop Tool and be sure to check “Content Aware” on the top toolbar. This option will only be available on the latest release of Photoshop, so if you haven’t upgraded your software, be sure to do so.
Next, click on your image to activate the Crop Shield. Bring your cursor to the outside edge of your image and make sure a curved double arrow appears, this is the cursor for rotation. Once the rotation cursor appears, click and drag your mouse to rotate your image and click Enter. The Content-Aware Crop tool will rotate your image and fill in the corners with information taken from the rest of the photo.

Click on your image to activate the crop shield, the mouse over one of the sides of the image until you see the double arrow. Click and drag outwards in the direction you would like to extend your canvas.
This Tool will work better on simple images like a beach scene.
