Overview

Lightroom is offered in two versions. The first version, known as Lightroom Classic, stores files locally and has the most extensive set of features. The second version, known simply as Lightroom and formerly known as Lightroom CC, stores all uploaded photos and edits on Adobe's cloud servers and allows access through desktop, mobile, and a web browser. Lightroom and Lightroom Classic are two separate programs that store photos and settings separately, although Lightroom Classic supports limited syncing of photos and settings with Lightroom. Both Lightroom and Lightroom Classic are non-destructive editing software that save edits as parametric instructions, separate from the original image. This allows the user to make changes to the image without any loss in quality and without modifying the original files, in contrast to

are not supported, but masking can be used for localized adjustments. Develop settings can be applied as a batch to multiple photos, and saved as a preset for quick access. Presets are interchangeable between both versions of Lightroom and can be shared with other users. Lightroom and Lightroom Classic include several presets that can be used as starting-off points for editing. There is a large market for develop presets geared towards applying a pre-conditioned look. Both versions of Lightroom are closely integrated with Photoshop; users can make adjustments in Lightroom, export the photo into Photoshop for additional pixel-level editing, and then reimport the photo into Lightroom for finishing touches. Lightroom Classic contains features not present in the cloud-based version of Lightroom, such as virtual copies, creating books and slideshows, proofing photos for print, creating

History

In 1999, veteran Photoshop developer Mark Hamburg began a new project, code-named ''Shadowland,'' a reference to the 1988 kd lang music album of the same name. Hamburg contacted Andrei Herasimchuk, former interface designer for the Adobe Creative Suite, to start the project. It was an intentional departure from many of Adobe's established conventions. Forty percent of Photoshop Lightroom is written in the scripting language Lua. In 2002, Hamburg left the Photoshop project and in fall of the same year he sent an experimental software sample named ''PixelToy'' to his former teammate Jeff Schewe for review; in 2003, Hamburg presented Schewe a first version of Shadowland in a very early UI version. After 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 accelerated around 2004. Herasimchuk chose to leave

On January 29, 2007, Adobe announced that Lightroom would ship on February 19, 2007, priced at $299 US, £199 UK. Further beta releases followed. Notable releases included ''Beta 3'' on July 18, 2006, which added support for

, available with a Creative Cloud subscription. On January 15, 2015, Adobe released an Android version alongside Lightroom web, which allowed cloud-based photos to be accessed and edited through a web browser. Photos and edits are saved to the cloud and synced between devices. On October 18, 2017, Adobe released Lightroom CC as the desktop counterpart to Lightroom for mobile; the older version of Lightroom was subsequently renamed to Lightroom Classic CC. Lightroom CC is a separate application and can be installed alongside Lightroom Classic CC. Lightroom CC can be synced with Lightroom for mobile, with photos and edits available between desktops and mobile devices. Lightroom 6 was the last version of Lightroom that could be obtained with a perpetual license, and received its last update on December 19, 2017. All subsequent versions of Lightroom are only available through an ongoing Creative Cloud subscription. If the subscription is cancelled, Lightroom CC will retain user data for one year, while Lightroom Classic CC can continue to be used indefinitely to organize and export, but not develop, images. In 2019, Lightroom Classic CC was renamed to Lightroom Classic, and Lightroom CC was renamed to simply Lightroom.


Apple TV

On July 26, 2016, Adobe launched Lightroom on
