Adobe Lightroom is a photo organization and editing software that allows users to import, organize, edit and export images. It performs non-destructive editing on RAW and JPG files. Lightroom's key features include organizing images with keywords and metadata, performing basic edits like exposure and lens corrections, creating HDR and panoramic composites, and exporting images for printing or sharing. While it lacks some advanced editing tools found in Photoshop, Lightroom integrates well with Photoshop for further editing in a photo workflow.
