CHanging image capture time.

[PeterAit]

Is there a way to tell whether an image's capture time has been changed in LR? I needed to add 4 hours to a huge batch of images (because I forgot to reset the camera's clock) but I screwed up somehow and changed only some of them. I now want to change the rest.

In the Library module - Metadata panel choose EXIF and IPTC view from the pulldown in the panel header.  Scroll down a bit and you will see three dates. When you use the Metadata>Edit Capture Time… function, it updates the Date Time Original field.  Comparing it to the other two date fields will usually tell you whether or not an image has had its capture time changed.

This may be of help
depending on how many you have done.

4. (Optional) To revert the capture time back to the original, select the photos in the Grid view or the Filmstrip and choose Metadata > Revert Capture Time To Original.

and then start again?
