Lightroom is a great photo editor, but it can be difficult to create composite photos. Composite photos are photos that are made up of parts that are not related to each other. For example, you might make a composite photo of all your friends and family together, and then make a separate photo of each person individually. There are two ways to do composite photos in Lightroom: by using the layers feature or by using the merge command. The merge command is the easier way to do composite photos because it allows you to combine different parts of a photo into one image. To use the layers feature, first open the photo you want to create a composite from. Then, click on the layer thumbnail in the left column of the Layers panel. The layer thumbnail will have three lines running through it: one line is for the original image, another line is for the copied image, and another line is for the merged image. To merge two images together, first click on one of the lines in the layer thumbnail and then drag it over to another image in your library. Once you have dragged it over, release your mouse button so that both images will be merged into one.
