It was Photoshop developer Mark Hamburg who started Lightroom, with a project code-named â€œShadowlandâ€ in 2002.
He enlisted Phil Clevenger to design the new look for the application. One interesting note about Lightroom is that 40 percent of its implementation was written in Lua (Portuguese moon), a dynamically typed language intended for use as an extension or scripting language.
Engineering talent for Lightroom was provided by a Minnesota-based team who had created Adobeâ€™s ImageReady application.
On January 9, 2006 Lightroom was released to the public as a Mac-only beta. Windows support was added in Beta 3 which was released on July 18, 2006.
Adobe Systems officially announced on January 29, 2007 that Lightroom would ship starting February 19 at a price of $299 ($199 introductory price up to April 30).
The rest, as they say, is history.
