Whay did you "reinstall iPhoto today"? Did you also "reinstall" the iPhoto library? What version of iPhoto and of the OS?
We must have details to try to help
And your request may be like asking how to get your running again after the gas tank shoed empthy without adding gas to it - depending on what is wrong it is very possible that the only solution is to rebuild the library
I reinstalled iPhoto '11 because it stopped opening after repeated library repairs which have been caused
by frozen Preferences, when I tried to change editor there.
I didn't touch the library. I did exactly what is recommend. Uninstalled iPhoto, all the pkg files deleted.
Everything is ok, except the problem with dates. I checked the exif on few photos, the dates there are fine.
Many photos have double dates, a date that can be edited, and a date in a tiny grey font, right beside.
Rebuilding or repairing the library ?
iPhoto is 9.4.2 on Mountain Lion, which I installed yesterday.
There are two kinds of metadata involved when you consider jpeg or other image file.
One is the file data. This is what the Finder shows. This tells you nothing about the contents of the file, just the File itself.
The problem with File metadata is that it can easily change as the file is moved from place to place or exported, e-mailed, uploaded etc.
Photographs have also got both Exif and IPTC metadata. The date and time that your camera snapped the Photograph is recorded in the Exif metadata. Regardless if what the file date says, this is the actual time recorded by the camera.
Photo applications like iPhoto, Aperture, Lightroom, Picasa, Photoshop etc get their date and time from the Exif metadata.
When you export from iPhoto to the Finder new file is created containing your Photo (and its Exif). The File date is - quite accurately - reported as the date of Export. However, the Photo Date doesn't change.
The problem is that the Finder doesn't work with Exif.
So, your photo has the correct date, and so does the file, but they are different things. To sort on the Photo date you'll need to use a photo app.
In Events, under every photo, where Title supposed to be, shows 12 Nov, 2010 or 2011...2008..etc.
When you place a cursor, instead of date shows "no title".
The photos with some title, don't have dates.
But all photos have the same wrong dates in smaller grey font under the title.
I know it's kind of confusing what I have.
When scrolling in 'Photos', month and year appear to be correct.
The 'info' shows the same 12 Nov. 2010...
I can of course manually write the correct date for each event, from exif info. Only it will take time.
any software that can fix the dates, to extract data from exif info and apply to iphoto ?
