I have 13,000 photos in iPhoto, which I began importing eight years ago (scanning old photos, importing digital photos). I had no problems with my Power Mac G5 and its OS, and the earlier versions of iPhoto. Then I got an iMac, shifted the photos from the G5, and no problems. I continued to introduce into the iMac Apple's new OS and new versions of iPhoto, and no apparent problem. In fact I can document the following with my Mac:
3/11 upgraded to IPhoto '11 (current version 9.4.2)
3/11 upgraded the OS to 10.6.3 Snow Leopard
7/11 upgraded the OS to Lion (current version 10.7.5)
I thought I was doing the right thing by upgrading soon as new OS and new iPhoto came out. Now I'm not so sure.
The past year I have not done any editing of my older photos. I just went to edit some older photos and as I clicked on the photo, then edit, on the right side I get the message, IMAGE CANNOT BE EDITED - This photo was previously edited with another application of with an early version of iPhoto. Duplicate this photo to edit it.
This message applies to my first 10,000 photos. I have spent hundreds of hours editing these photos. The 3,000 photos from July 2009 are OK and can be edited.
So, must I duplicate each of these first 10,000 photos, each in their respective albums, to continue editing them? This will take hundreds of hours more. How in the world can Apple have such a poor transition between one OS and another, or between one IPhoto and another? Has anyone experienced this situation before? Is there a solution to my problem, or am I stuck with duplicating 10,000 photos (and deleting 10,000 photos), album by album, and then reediting them?
FYI, I have a a Mac Mini with iPhoto version 9.2.3 and OS X 10.6.8. It has about 11,000 of these photos on it (I haven't loaded the last 2,000 photos onto it) and it does not demonstrate any of these editing problems.
Your observations and recommendations are recommended.
Yes - although it is hard for me to believe that you ae actually going to re-edit all 10,000 photos from over 3 yeatrs ago - I find one or two a month that I need to duplicate to make more edits to - I have over 50,000 photos (no idea how many of them fall into this catagory). The key is that there is no need to duplicate anything unless you want to re-edit a previously edited photo - unedited photos should be fine andphotos that do not need more editing are fine
Basically the change came in iPhoto '11 version 9.3 due to the single library integration between iPhoto and Aperature that makes certain prior editing incompatible so you duplicate teh edited photo sand it becomes the new original -- see http://support.apple.com/kb/HT5260?viewlocale=en_US&locale=en_US
