Adobe Photoshop Lightroom is a photo processor and image organizer developed by Adobe Systems for Windows and OS X. It allows viewing, organizing and retouching a large number of digital images. Lightroom’s edits are non-destructive. However, despite sharing name with Adobe Photoshop, it is incapable of performing many of 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 not a file manager like Adobe Bridge: It cannot operate on files unless they are imported into its database first; in doing so, Adobe Lightroom accepts only recognized image formats.
