Similarities between Photoshop and Lightroom are that you can use the same image formats such as PNG, JPG, RAW, etc. They also share similar editing tools such as filters, effects, brushes, crop tools, and much more. You can also access all photos you’ve edited in the apps.

Differences between Photoshop and Lightroom are that Lightroom is easier to find the editing tools and allows you to edit multiple photos at once, whereas Photoshop does not. Photoshop is able to put layers on top of each other, but in Lightroom, you have to use photos that are not layered.
