After a splendid day at the track, I uploaded all the photos I had taken which I was really too tired to do as you will see.
I showed D the photos that up to that point I had thought were among the possible best of the lot. Fortunately, he did get to see them because I then proceeded to delete ALL of those photos.
Clearly I am also too tired to figure out how to restore them because nothing I do (including searching the recycle bin or my memory card ((yes, it was still attached to the computer when deletion occurred!)) for them) seems to work.
Right now I'm not too happy as you can imagine so I'll be back after the weekend.
