What are the required steps in RAW processing using Adobe CS2 Photoshop & Bridge.
1) Double-click the raw image thumbnail in Bridge, this starts the ACR preview.
2) Click the "open" button, and wait for the image to open in Photoshop.
But that doesn't have much to do with Bridge, you should get the same effect by double-clicking on the raw file, provided that the file type has been associated with Photoshop.
Whether you want to adjust things in ACR, such as white balance (probably a good idea!), exposure tuning, cropping/orientation, etc., is entirely up to you.
If what you want is a tutorial on how to use ACR to do raw processing, the net is full of them.
