You can also invoke this command from within Lightroom for a selected group of images (right-click > Edit In > Merge to Panorama in Photoshop). In Photoshop, Choose File > Automate > Photomerge.Use the following steps to merge overlapping photos into a single panoramic image. You can use Photomerge to combine images that are tiled horizontally, vertically, or both. You can take several images and combine them into a seamless panoramic image. Creating this type of image in Adobe Photoshop is super easy thanks to the Photomerge command. One of my favorite styles of image is a panoramic photo.
