I have Photoshop Elements 15. Many of my images were created from scans of 35 mm slides. In the Organizer I use the Date/Time field to indicated the year and month the original image was captured on film. If at some point later on I decide to edit the image with Photoshop CC and then save the image, I wll most likely want the image's thumbnail updated so that I see the edited photo in the Organizer. In the Photoshop Elements Organizer, if I request the tumbnail be updated, the Organizer changes the image date to the date the file was created, thus causing loss of important meta data about the image.
