Adobe Photoshop Lightroom

Yesterday Tom asked me about adobe photoshop lightroom. So I told him that adobe photoshop Lightroom is a photography software program developed by Adobe Systems for Mac OS X and Microsoft Windows, designed to assist professional photographers in managing thousands of digital images and doing post production work. It is not a file browser like Adobe Bridge, but rather an image management application database which helps in viewing, editing, and managing digital photos.
History
In 2002, veteran Photoshop developer Mark Hamburg began a new project, code-named “Shadowland". Hamburg reached out to 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 Lua scripting language. 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. Herasimchuk chose to leave Adobe Systems at that time to start a design company in the Valley, and then Hamburg chose Phil Clevenger, a former associate of Kai Krause's, to create a new look for the application.
Photoshop Lightroom's (LR) engineering talent is based largely in Minnesota, comprising the team that had already created Adobe’s ImageReady application. 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 previous Adobe evangelist, rounded out the early team, filling the Product Manager role.
Beta development
On January 9, 2006, an early version of Photoshop Lightroom, previously just called Lightroom, was released to the public as a Macintosh-only public Beta, on the Adobe Labs website. This was the first Adobe product released to the general public for feedback during its development. This method was then later used in the development of Adobe Photoshop CS3. Further Beta releases followed. Notable releases included Beta 3 on July 18, 2006, which added support for Microsoft Windows systems. On September 25, 2006, Beta 4 was released, which saw the program merged into the Photoshop product range, followed by a minor update on October 19, which was released as Beta 4.1.
Version 1.0
On January 29, 2007, Adobe announced that Lightroom would be shipping on February 19, 2007. US list pricing was set at $299. The UK retail price was £199. Lightroom v1.x is not updated when an upgrade to v2 is installed; a new serial number is required, too.
Version 2.0
Adobe Photoshop Lightroom 2.0 Beta was advertised in official emails from Adobe in April 2008. New features include:

* Localized corrections (edit specific parts of an image)
* Improved organization tools
* Multiple monitor support
* Flexible printing options
* 64-bit support

The official release of Lightroom v2 was on July 29 2008, along with the release of Adobe Camera Raw v4.5 and DNG Converter 4.5. Adobe has added DNG Camera Profiling to both releases. This technology allows custom camera color profiles, or looks, to be created by the user and saved. It also allows profiles matching the creative styles built in to cameras to be replicated. Adobe released a complete set of such Camera Profiles for Nikon and Canon models, in addition to basic Standard Profiles for all supported makes and models, through Adobe Labs, at the same time as the Lightroom v2 release. This technology is open to all programs compliant with the DNG file format standard.
Version 3.0
Adobe Photoshop Lightroom 3.0 beta was released on October 22, 2009. New features include:

* New import pseudo module
* Grain
* Publish mode
* Backup on export
* Custom package for print
* New noise reduction
* Improved Sharpening tool
Features
Unlike traditional image editing software, Photoshop Lightroom is focused on the following workflow steps:
* Library - image collection review and organization - similar in concept to the 'Organizer' in Adobe Photoshop Elements
* Develop - non-destructive RAW and JPEG file editing
* Sideshow - tools and export features
* Print - layout options and preferences
* Web - automatic gallery creation and upload
The Develop mode has a number of standard presets for color correction or effects and supports the sharing of custom presets online.
