Open in Camera Raw from Bridge
You can open RAW images in Camera Raw right from Bridge in Photoshop CS3. This frees up Photoshop to continue working on your files while they're being processed in Camera Raw. Just select one or more images in Bridge, Control-click (PC: Right-click) on them, and choose Open in Camera Raw. This will open the image(s) in Bridge's Camera Raw rather than Photoshop. You can also use the keyboard shortcut Command-R (PC: Ctrl-R).
