Lightroom is a photo management software that allows users to organize, edit, and share their photos. One of the features of Lightroom is its ability to stack photos. What is stacking? Stacking is when you group multiple photos together so that they appear as one image on your screen. When you stack photos, Lightroom creates a new file called a “stack” which contains all of the photos in the group. You can then use this stack to make edits to all of the photos at once or you can select individual photos and make edits to them individually. Why would I want to stack my photos? There are a few reasons why you might want to stack your photos. If you’re trying to create a collage or montage, for example, stacking your photos will make it easier to put together an image that looks cohesive. Additionally, if you’re editing multiple images at once and want them all onscreen at the same time, stacking will help with that too. Finally, if you’re working with large files and don’t have enough space on your hard drive for each photo individually, stacking can help reduce the size of the file overall. ..
