I just shut down iPhoto, then the computer. Then I restarted both. The photos came up, but there are no faces shown (Tab Info, Faces). There is a pinwheel sorta thing next to Faces on the left-hand panel. One cannot select Add a Face from the Faces function. The pinwheel lasts at least 10 minutes. When it goes away, the symptoms above recur.
Larry, I'd used ILM to rebuild the library and that library is the one that was really skrewy. I went back to the original and it has far fewer issues. The issue is still around faces, but the ILM rebuild apparently made it worse. So, going back to the original library, the issue is this:
- On some photos, some or all of the faces shown in the right-hand column (Info - Faces) do not show up on the photo. These two approaches seem to fix it:
- If there is any name showing in the photo, it is usually one. Delete it. All of the names will disappear in the Info - Faces panel. Then add them all back in.
- If there is not a name showing, add faces for each name showing in Info-Faces. In this case no new name is shown in Info Faces.
This leads me to the thought that I have a "slightly" screwed up faces database. Very uncomfortable with that.
I had and still have the same problem. Here is what partially soved it for me.
1. Go through all your photos for one person. Flag any that have a problem.
2. Open Flagged album.
3. For each photo delete all found faces.
4, Select all Flagged photos, then Photos > Detect Missing Photos.
5. Open each photo and assign the correct name to the found Faces.
When the original found faces become corrupt no rebuilting by iPhoto or iPhoto Library Manager will fix the problem. Deleting the corrupt found face boxes, then redetectiing the faces creates uncorrupted data structures.
A major problem is that the data corruptions appears to be associated with the photo and not restricted to the found faces which have obvious issues. If you delete only the incorrect found face boxes but leave those which seem correct, I have observed that applying Detect Missing Photos may result in the originally correct found faces being changed to have something wrong.
Another problem is that if you delete a correct found face box and then applying Detect Missing Photos finds exactly the same box, iPhoto remembers you have deleted it and does not replace it. In my hands this has happened in about a quarter of the photos. At least some of my photos have been repaired.
An observation that may confirm we are seeing similar coruption is the shape of the incorrectly placed found face box. In many cases I have seen a vertical rectangle which is offset from the found face. For different corrupt found faces this rectangle may be in differnt places in the photo, or of a different size, but the height to width proportions seem similar. Do you see found face boxes like this?
Thank you. I was not previously aware of the command Detect Missing Photos--I will try out your advice the next time I find a corrupt photo. I have not seen a vertical rectangle like you mention above. What I typically see is a very small square box, often in the lower center of the photo, often with several stacked on top of each other. Yesterday I tripped over a photo which had everyone correctly identified (I had done that earlier) however each face was replicated by a small box slightly below the original box, each with the appropriate name filled in I also had the experience of looking in faces for a specific photo and not finding it. I went to photos and validated that the face was properly tagged, then went back to Faces and it was there (actually, looked like 20-30 photos had disappeared and reappeared.
My fear remains that this indicator of a corrupt database will never be fixed by repairing individual photos and one day the entire database will collapse. While I know I won't lose the photos, I have about 6,000 with date, place, and faces all tagged. Losing that would be catastrophic.
I see in other threads that others directly manipulate the faces database using MySQL. Any thoughts on that?
Glad to see my suggestion worked for you. Over the last week I have been similarly trying to remove more corrupt data from my library of over 25,000 photos. The corruption I see is as described earlier, plus the small square boxes you describe, plus more:
tiny boxes with essentially no area at the lower left corner of the photo
photos with no found face box yet the Info pane lists names of found faces
large square boxes labled with a correct name but in the wrong locations in the photo
found face boxes appear correct but the thumb is from some other part of the photo
found face boxes appear correct but the thumb is rotated 90 degrees
Probably there are others that I do not remember right now.
As might be expected with this level of incorrectly identified faces, prediction of matching faces has been poor. As I have deleted obvious corruption from the database I have also verified correct predictions and marked incorrect predictions. Predictions are now much better.
This corruption remained after merging three libraries using iPhoto Library Manager, then doing all of iPhotos internal rebuilds several times, then rebuilding the library using iPhoto LIbrary Manager. When I finish removing what corruption I can manually I plan to rebuild everythng once again. Even with all this cleaning I am concerned that I will miss some corrupt data, and the corruption will propagate.
I have not heard of using MySQL on Faces or iPhoto. Directly manipulating internal iPhoito structures sounds like asking for trouble, but we already have lots of trouble with no apparent solution. I will investigate. Thanks for the tip. Have you tried it?
