Adobe Lightroom (officially Adobe Photoshop Lightroom) is a family of image organization and image manipulation software developed by Adobe Systems for Windows, macOS, iOS, Android, and tvOS (Apple TV). It allows importing/saving, viewing, organizing, tagging, editing, and sharing large numbers of digital images.
Lightroom’s edits are always non-destructive by keeping the original image and the edits applied to it saved separately. Despite sharing its name with Adobe Photoshop, it cannot perform many Photoshop functions such as doctoring (adding, removing or altering the appearance of individual image items), rendering text or 3D objects on images, or modifying individual video frames. Lightroom is an image management and editing program also developed by Adobe, the same folks who created Photoshop.
Using Lightroom, photographers are able to work through their images from import, to sorting and organization, to processing, and finally all the way to export and sharing on the web. Lightroom is not a file manager like Adobe Bridge. It cannot operate on files unless they are imported into its database first, and only in recognized image formats.
Initially, Adobe Lightroom was one product only. But as of 2017, it has become a family of products consisting of Lightroom CC and Lightroom Classic CC. While similar, these two products have significant differences, mainly in how they store images and interact with Adobe’s cloud storage offering, and in feature parity.
