May I thank everyone that offered advice.

The hangover from this error was that my confidence was knocked into a cocked hat.
The recovery was very good, I now look very closely at every editing change and storage of the images. No postings on AP as yet although I suitable photos which I will post.

My advice, back up as much as possible in any way that works. Keep one copy on separate storage device or cloud.


Once again, many thanks, Journeyman.
