Adobe Photoshop Lightroom or Lr/LR is a program that has been developed by Adobe Systems as a photo processor and image organizer for Windows or OS X. It allows the user to be able to view, organize and edit a large number of images. Even though it shares a name with Adobe Photoshop, it cannot do many of the functions that is done by Photoshop. This included removing, adding or altering image appearance, rendering text or 3D objects on images or modifying video frames. The software is not a file manager like Adobe Bridge. It cannot operate on files unless they are imported into the database first, only in the recognized formats. It was created in the C++ and Lua programming languages.
