The Tilt Tool allows you to rotate your images without cropping them. This may come in handy for creating graphics or giving your image an extra flair.
Step 1: To get started, open up an image in the Photo Editor.
Step 2: Under the Edit menu, choose 'Tilt' under the 'Miscellaneous' section.
Step 4: By default it will have a transparent background, but you can add in a color by clicking the Background Color icon and choosing a color from the color wheel. You can also use the eyedropper tool to pull the color you want to use for the background from the image itself.
