Scanned photos do not have EXIF fields in the file and cannot have EXIF Capture Dates added. There may be some UNIX command that will do the trick but I don't know of any way. The best you can do is to change the file created and modified date to the one you want. There are some 3rd party apps that can do the trick. Go to VersionTracker.com and do a search for "change date", "change file date" or something like that. You'll get a list of potential candidates.
One trick that I frequently use is to select all the affected pictures, then select "Photos -> Adjust And Time", change the time by 1 second, and click on "Modify Original Files". That will do a small non-consequential adjustment to the timestamps, but also write the new timestamp into the EXIF data of all the pictures. If the 1 second change bothers you, you can repeat the step, but this time subtracting one second from the time.
Oh tilman... After reading your simple and obvious idea I had a "Why didn't I think of that?" moment. So I fired up iPhoto and added 1 second to every photo with the modified original checked.
Results? Well.... not really.... After it did it, the correct dates were in fact added to the EXIF! But when exporting, or bonjour sharing they STILL went to a random January 31st 2000. Only a few had the correct date and when checking the EXIF of the imported files, there was no date there! I have no idea why.
As a side effect, after adding 1 sec to the photos about 3000 pics lost their GPS info as well. Why would it do that, from changing the dates I wouldn't know.
I went back to my backed up library of before any changes...
Such a simple thing, so complicated.
Thanks for the input.
I have been struggling with iPhoto's lack of EXIF functionality and compatibility for YEARS. It has never worked right and has never been fixed.
My solution has been to modify my workflow. A program called Graphic Converter will do everything you need and more. It used to be bundled with Macs, but now you have to buy it.
Use it to modify file date/time, EXIF info, GPS info, IPTC info, and pretty much anything you could ever do to a graphics file. It is not very user-friendly and has a less-than-stellar interface but once you figure it out, it will do just what you need.
Work on all your files with it, getting the dates right and so forth, and then your final step should be to import to iPhoto for viewing and safekeeping.
Or use a tool like Phoshare (Open Source at http://code.google.com/p/phoshare) to export your iPhoto library with all the iPhoto information (title, description, keyword, ratings, date, faces, places) merged into the metadata.
You might want to disclose that you actually wrote Phoshare yourself.
I took a look at it but haven't tested it. Its claimed functionality looks promising, but I don't see a way for a user to import the folder tree the program creates to get everything back into iPhoto. The interface is a bit rudimentary and has a misspelling.
I clicked on the Documentation link on the Google page and was told I didn't have access.
Sorry about the documentation link, that is fixed now. Yes, Phoshare was written by me, but it's free to use, shared as Open Source Software. It has been available for about a year (previously known as iphotoexport). It's main purpose is to make your iPhoto library contents accessible to other programs, which is what the original post was asking about (e.g. exporting your library with the EXIF data properly populated).
