When ever I change a picture, PSE12 changes the Date Created to the current date&time thereby destroying the original date&time. This causes the sequence of my pictures to be altered when they are exported. IMHO this is a BUG in PSE12 (Macintosh, OS 10.9.4)
If Microsoft Word & Excel can retain the Create Date information, I don't see why PSE12 cannot do the same.
IMHO it is important that the original create date be preserved. My wife & I both take pictures while on vacation (we synchronize our cameras, SONY & NIKON, with the same date & time). Were we to skip PSE12 editing altogether and uploaded our JPGs to our photo processor, said JPGs could be sequenced by "date taken" thus insuring the pictures of the same scene taken at roughly the same time would appear side-by-side in our photo processor. Since PSE12 destroys the Create Date & Time when a JPG is altered this is not possible.
IMHO retaining the Create Date & Time should be a TOP PRIORITY as a revision to PSE12 or a new release (PSE13?).
