Finding original filename from exported renamed jpeg

Question

Typically I import over 1,000 images from a job into a project.
I edit and export around 500 final images as jpegs renamed sequentially for my client.
My client asks for say a colour version of a particular black & white image but the file info on my clients image does not contain any reference to the original filename.
Is there any way to include the original filename in exif data when exporting the images from Aperture?

Answer 1

There's a simpler method which you might consider using.
What file naming convention are you using on import? Why not rename your camera files on import into Aperture something like " dateclient_joboriginalfilename ". You could then either use that, or export with that name plus a sequential numbering scheme.
Or -- the same as Viren's excellent suggestion -- select all the files you are going to export, create duplicate versions, with the duplicates still selected create a new Album containing all of them, then use Aperture to rename the Versions prior to export and export using the Version name. Versions don't use much space (they are text files), and you end up with an Album of neatly numbered Versions of just the photos you've given to your client +with the file names of their files exactly the same as your Aperture Version names+.
