Lightroom also offers the ability to edit photos. You can also mark photos from a shoot that you want to keep versus those that are just plain bad (culling). It offers a way to catalog your photos, apply keywords to them, search through the photos by those keywords and by other attributes like what camera/lens was used to take the photo. Lightroom offers functionality to manager your photos, something photographers call Digital Asset Management or DAM for short. Let’s walk through the functions each can do a little here.
Lightroom and Photoshop are very different programs. This post explains exactly what each is and how to choose between them.

Adobe isn’t doing themselves any favors having two products (Lightroom and Lightroom Classic) named so similarly.
