Create versions of a photo
Occasionally, you may want to make a second version of a photo. For example, you might want to create another version of a photo and apply different exposure settings or other adjustments, or change it for a specific use, such as for placement in a webpage or book.
You create a new photo version by duplicating either the original image or the currently selected version. When you duplicate a version, all of the changes you’ve made to the first version are carried over to the new version. If you’ve made a series of adjustments to a photo and now you want to start from the original photo and make different adjustments, you can duplicate the original and start with a fresh, unchanged photo. In contrast, if you plan to use the same adjustments in multiple versions, you can make those adjustments first and then duplicate the version with the adjustments applied.
