How does Lightroom 2 work with Adobe Camera Raw?
If you work with photographs in Photoshop CS4 or Adobe Bridge, you use Camera Raw to achieve the same kinds of editing as you would in Lightroom. In fact, Lightroom uses the same underlying processing engine as Camera Raw, which delivers consistent and compatible results across Adobe applications. Adobe understands that individual photographers work in many different ways. We are committed to providing customers not only with the choice of which software to use, but also with the ability to use multiple applications together as needed.
