[KPhotoAlbum] EXIF (and equivalent META data for non-jpeg) creation date

The first thing I do when I move photos from the camera to the computer 
is to change the photo name to include the date taken.  So, the new name 
would look something like 100622_2343.jpg.  I store them in a series of 
directories of the form Photos->Year->Month->Other-breakdown. 
KPhotoAlbum is then used to categorize the photos.  My only complaint is 
that KPA only runs on Linux and I am primarily a Microsoft user for 
various reasons, so it sometimes takes a while to add categories.

I have not seen any problems with applications changing the date taken, 
but then I archive the originals and only modify copies.  As Jasper 
says, KPhotoAlbum does not modify the creation date (or any other 
parameter) unless explicitly requested. Most applications can be 
configured to retain the date taken, so you may want to check your 
applications configuration settings.

Hope this helps,
