Adobe Photoshop Lightroom is a graphic editor designed to manage and process digital images. It is, in technical terms, an end-to-end solution for photographers and digital photo enthusiasts. It offers a wide range of digital instruments to adjust RAW images to look their best.
The best way to demonstrate its purpose is to imagine how photographers used to process photos after taking them. Adobe’s product is the dark room of the digital world, simplifying the manual work that specialists used to do in order to bring images to the final state.
Adobe Photoshop Lightroom bundles five separate stages that photos go through to meet the end result: Library - a section where the images of interest are gathered, Develop – environment for performing the actual editing, Map – section that allows you to add geo data, Book – for creating albums and publishing, Slideshow – dedicated to designing presentations, Print – deals with layout options and Web – focuses on exporting galleries to the web.
Editing includes basic actions (exposure, brightness and contrast, clarity, vibration), tone curve, HSL, color, or black and white, split toning, details (sharpening, noise reduction), effects, and camera calibration. Details can be maximized by adding dark shadows or bright highlights, while the noise reduction features ensures a natural look for your photos.
Since it includes such a rich photography toolset that accomplishes such a wide array of tasks, from organizing, to editing and publishing, Lightroom can be easily categorized as a workflow productivity tool as well. It provides the necessary controls for refining white balance, correcting chromatic aberrations, lens and perspective correction as well as intelligent image sharpening that enhances detail without inserting uncanny artifacts.
Although the powerful set of features recommends Adobe Photoshop Lightroom to professionals, it can appeal to amateurs as well. Its intuitive one-click adjustments and multitude of effects and correction tools coupled with an intuitive and flexible environment make it suitable for both categories of users.
