Embed original filename in EXIF
I have tens of thousands of photographs on my computer. I often take one, or a few, or a set, and process them for some specific purpose. I often rename the files to represent the occasion. At some later time I want to find the original and rework it, but because I renamed it I can't find it easily. My originals, with their original file names are stored doubly backed up on separate hard drives. So if I could look at the processed image's EXIF data and extract the original file name after which it's fairly easy to find the original.
Actually it would be nifty to specify one or more processed files and automatically search for the original (given perhaps a clue where these might be stored)
Is there a way?
I generally use EXIF Viewer to look at the EXIF data and I don't see the original file name. Similarly in Aperture.
Thanks,
Pete
