Thanks, Bruce.  And the requirement for EXIF is a good one to date the images.  Film shooters may want to contact the mods....my suggestion, not theirs.     Folks not knowing how to save EXIF may want to see the thread on the current forum page. And, most digitals will save EXIF with menu options to even show you how to see it when shooting. 

Best wishes to all in this challenge.       TomDArt
