History of the Adobe Lightrom.

Adobe Lightroom (Lr or LR) is a photo processor and image organizer developed by Adobe Systems for Windowsand macOS. It allows viewing, organizing and retouching large numbers of digital images.Lightroom's edits are non-destructive. 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 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.In 1999, veteran Photoshop developer Mark Hamburg began a new project, code-named Shadowland (meant as a reference to the 1988 KD Lang music album of same name). Hamburg contacted Andrei Herasimchuk, former interface designer for the Adobe Creative Suite, to get the project off the ground.The new project was a deliberate departure from many of Adobe's established conventions. 40% of Photoshop Lightroom is written using the scripting language Lua. In 2002 Hamburg finally left the Photoshop project and in fall of the same year he passed around a first experimental software sample that bear the name PixelToy to his former team mate Jeff Schewe for review, and later in middle 2003 presented a first version of Shadowland in a very early UI version to him.After a few years of research by Hamburg, Herasimchuk, Sandy Alves, the former interface designer on the Photoshop team, and Grace Kim, a product researcher at Adobe, the Shadowland project got momentum around 2004. However, Herasimchuk chose to leave Adobe Systems at that time to start a Silicon Valley design company. Hamburg then chose Phil Clevenger, a former associate of Kai Krause's, to create a new look for the application.

Photoshop Lightroom's engineering talent is based largely in Minnesota, comprising the team that had already created the program Adobe ImageReady. Troy Gaul, Melissa Gaul, and the rest of their crew (reportedly known as the "Minnesota Phats"), along with Hamburg, developed the architecture behind the application. George Jardine, a skilled photographer and prior Adobe evangelist, rounded out the early team, filling the Product Manager role.
