I'm new to RAW files, so I see an .XMP file that accompanies it. I believe it is the metadata collected by the camera right? 1. Why isn't this information embedded directly into the RAW file somewhere? 2. If I change the metadata of a RAW file within Bridge, will it write to that .XMP file? What happens when I write to the metadata of a JPEG, it writes inside the actual JPEG right? 3. After I convert the RAW file into a TIFF or whatever, does that .XMP file data get put into the TIFF or whatever? Thanks!
