There is an article in the current (Sep/Oct 2006) edition of "Digital PhotoPro" magazine called "Simple Camera Importing" (Page 118). The article claims that "Robert Stucky (Adobe) has written an automation script for Adobe Bridge called "Import from Camera." While the name of the script identifies its main purpose, Import from Camera is much more than just a simple "ingestion" script. This powerful script can also:
Batch rename your photos using flexible and customizable templates.
Preserve the original file name in each photos metadata.
Append (or replace) metadata templates containing, for example, copyright and ownership information.
Copy duplicate (backup) versions of each photo to the designated secondary path."
The article goes on to say that "The Import from Camera dialog box is accessed via Bridge's Tools menu; however,you'll have to configure the script before you can use it the first time." (and then describes the procedure)
I have not read the article nor do I have personal experience with the script so this is merely a FYI post.
