Adobe Photoshop Lightroom CC 2015 (formerly known as Adobe Camera Raw) is a powerful digital photography workflow application that offers advanced tools for managing, processing, and exporting images from camera raw files to the final output format.

Released in June 2013 alongside Creative Cloud version of other CS6 applications including Illustrator, InDesign, Dreamweaver, Muse, Premiere Pro, Photoshop CC (CC stands for 'Creative Cloud') and After Effects CC. The latest versions are available only through subscription-based Adobe Creative Cloud service which provides users with access to all software as well as regular updates plus 20GB of cloud storage per user account.

Key Features of Adobe Lightroom

1. HDR Merge: This feature allows you to combine multiple photos taken with different exposure settings into a single high dynamic range image.

2. Advanced Tone Curves: These provide greater control over tonal adjustments within images, allowing for more precise manipulation of shadows and highlights.

3. Local Developments Tools (UdT): UdTs enable users to apply non-destructive edits only where needed on selected areas within an open document - making it easier than ever before when working large files without affecting other parts outside those regions being modified!

4. HDR Efex Pro: This feature offers a range of effects that can be applied to high dynamic range images, including film grain and vignettes.

5. Lens Profile Support: Lightroom includes profiles for over 70 camera lenses from leading manufacturers such as Canon, Nikon, Sony and more.

System Requirements

Adobe Photoshop Lightroom CC requires Windows 7 with Service Pack 1 or later (32-bit/64-bit) operating systems to run smoothly. It also supports Mac OS X Lion (10.8 or higher). For optimal performance on older hardware configurations like lower end consumer grade laptops/netbooks running Win XP SP3+, we recommend using the x86 version instead of its bigger brother which requires Intel Core 2 Duo processor at least along with RAM >=4GB free space available across entire hard drive before installing anything else besides necessary drivers for graphics card etcetera.

In conclusion, Adobe Photoshop Lightroom CC is a powerful and feature-rich image editing software that offers advanced tools for managing, processing, and exporting images from camera raw files to the final output format. Its latest version supports Windows 7,8,10 and Mac OS making it compatible with most operating systems currently available in the market today.
