Photoshop Lightroom 5 from Adobe is a complete photo management and editing suite for Mac OS X and Windows. Ideal for enthusiasts and professionals alike, Lightroom takes a nondestructive approach to photo editing, leaving the original files uncompromised. All your adjustments and edits are stored in a database and applied to an image on the fly so that you'll always be able to go back to the original image. This enables you to execute as many post-processing adjustments on a photo as you'd like, without making permanent changes to the original image.
Lightroom also serves as a powerful organizational tool for your photographs. Organize photos to suit your needs via an intuitive folder-based data structure. Lightroom lets you store images on multiple storage devices, and it stores low-resolution previews of each image in its central database, allowing you to browse photos even when the original files are offline. You'll be able to search your images based on any number of criteria, accelerating the process of locating a specific image.
Lightroom's interface is divided into five major components: Library, Develop, Slideshow, Print, and Web. Each screen serves its own purpose, and you can go back and forth between them easily. There is some overlap in functionality, but for the most part, the components are compartmentalized.
The Library screen is where you organize and browse your photos. Enjoy full access to all folders in your library from this screen, allowing you to reorganize as needed. Apply keywords, ratings, color labels, and metadata additions to images. You can make custom searches to create "Collections" based on any of these criteria. The "Smart Collections" function updates on the fly as additional images meet your criteria. For example, you can have an up-to-date collection of all images that you've given a 5-star rating. There is also a "Quick Develop" panel allowing you to make minor adjustments to an image, without having to venture into the Develop screen.
The Library also serves as the gateway to import and export images. When you click "Import," the Import window expands to fill your entire display. Browse through your hard drive or a memory card to find images for import. You can leave the images in their original location, copy or move to a different folder, or copy and convert them to Adobe's DNG format. Apply Develop settings, add metadata, and add keywords during import, such as one for the camera used to capture the photos. Rename files and save a second copy to a backup drive during import.
When you've finished editing, use the Library screen to export your photos with ease. You can use the "Export" function, which brings up a window with numerous settings -- including image size, sharpening, file format, and the like -- that you can customize. There is a "Publish Services" section, enabling you to send images to your hard drive or Flickr with ease. Create as many presets for Publish Services as you'd like, giving you one-click access to frequently used export operations. This section can be further expanded via third-party plug-ins, available from Adobe's Lightroom Exchange website.
The second major component of Lightroom is the Develop screen. This is where you'll do the vast majority of your photo editing and toning. Perform any adjustment imaginable here, including color temperature, exposure, black levels, contrast, sharpness, and brightness, to name just a few. You can make adjustments via sliders or tone curves, discretely modify color channels, and convert images to black and white. Numerous presets are available, allowing you to quickly apply a certain "look" to a photo, and you can create your own presets based on your favorite settings.
The Develop screen also features useful History and Snapshot functions. History lets you browse through all of the adjustments you've made to an image, in the order that they were made, so that you can revert back to any stage in the image process. At any time, create a Snapshot of an image, which saves all of the settings you've applied, allowing you to continue to experiment with a photo after you've found a look you like.
Remove dust spots and red-eye from photos, thanks to Lightroom's spot editing tools. Create image masks to apply graduated filter adjustments to a photo, or use the brush tool to dodge, burn, and make other spot adjustments. You can add vignettes and simulated film grain to images, great for breathing analog life into digital photos.
With distortion correction, "defishing" of images captured via fisheye lenses can be done from within the program. Correct for both fisheye and rectilinear distortion, a capability highly useful for those shooting with extreme wide-angle lenses. Numerous lens profiles are included with the software, and you can save your own presets for oft-used lenses.
Lens corrections can also eliminate the keystone effect that ensues when your camera is not straight-on a subject. Basic crop and rotation tools are also available for quick and easy adjustments. If there is anything that can't be handled by Lightroom, it's easy to export a photo to Photoshop for more thorough editing; and any changes you make to an image in Photoshop will be automatically reflected in Lightroom.
Lightroom's other three screens are all about sharing your images. The Slideshow screen gives you all the tools necessary to create digital slideshows of your images, complete with transitions and music. View these from within Lightroom or export them to a PDF or video file to share.
The Print screen allows you to print your images in any way imaginable. Adjustable for many standard paper sizes, it lets you visually layout photos on them, allowing you to maximize the number of photos on a single page -- thus helping to reduce printing costs. Lightroom can automatically position photos so that space on a page will be used as efficiently as possible. Adjust prints for different paper types and color profiles, and add a signature plate if you wish.
The Web screen gives you numerous means of outputting photos to the web. Adobe includes a number of HTML and Flash galleries, allowing you to create a web gallery without any knowledge of programming. These can be customized to suit your needs, and third-party galleries are available via the Adobe Lightroom Exchange website.
Top new features in Lightroom 5 include Smart Previews, improved photo book creation, video slide shows, an Advanced Healing Brush for quickly making images spotless, an Upright tool for easily straightening images, and a Radial Gradient tool for emphasizing important parts of images.
Lightroom is sold as multiplatform software, which means it can be installed on either Mac or Windows operating systems. This is the English language version of the software.
