Lightroom is designed for photographers and focuses on photo editing and cataloging tools. It allows for non-destructive editing and has powerful yet accessible tools for color correction, cropping, and effects. Photoshop has more advanced graphic design tools and is better for fine-tuning images at the pixel level but is more time-consuming for beginners. The document outlines the differences between Lightroom and Photoshop and provides an overview of basic photo editing tools and techniques in Lightroom like temperature, exposure, HSL, and special tools for cropping, spot healing, and graduated filters.
