Step 1: Edit the photos with Auto Sync
Select the images you want to merge and open them into the Develop module. All these images should be highlighted if the filmstrip is visible at the bottom. You can also click on one of the images (with all other images still selected) to choose a reference image while making adjustments.
On the right, make sure that the Auto Sync button is toggled. Then, make the edits you would like to your image, and all selected photos will be synced and updated with the same adjustments.
