After a year in public beta, Adobe has released Photoshop Lightroom 1.0, a brand-new workflow tool that combines image editing and photo management with the ability to produce slide shows, high-quality prints, and Web portfolios. Like Apple’s Aperture, against which it competes, Lightroom is designed as a professional-level product that also appeals to serious amateur photographers. After a year in development, Lightroom is a feature-rich and powerful tool, even in its version-1.0 state.
