I process my landscape photos in Bridge, ACR, and PS. I put the original raw photo in a folder, open it, and make raw edits. Then I save it, from camera raw, as a tiff under a new name like "Half Dome Raw Edits." I now have two files in the folder. But I notice the original raw file has picked up the edits I intended to be only in the file I saved as a renamed tiff. When I open the original raw file, the sliders,etc, are as I left them when I finished editing. The file I save under a new name, as a tiff, has all the edits but the sliders are set back to their original default positions, so I can't see where I have left them. Can someone tell me what's going on, and how I can keep separate an unedited raw file and an edited, renamed tiff?
Your raw adjustments are saved in either an XMP sidecar file with the same base-name as your raw file but with an XMP extension, or less commonly in a central Camera Raw database. The settings are not in the raw file but if you view the raw file from an Adobe product then the adjustments are retrieved from the XMP/database and automatically applied. This saving of adjustments lets you exit Camera Raw and resume your editing setting later.
The TIF is a new file that doesn’t contain the raw data, naymore, and any adjustments are “backed in” so opening that file in the editor shows zeros for the adjustments, and any adjsutments you make to the TIF would be in addition to what was done in ACR when the TIF was created.
