What does the code in step 5 for exiftool do? #447
Description
The readme says "Most of your photos should have correct original EXIFs (metadata), but if you want, you can insert them everywhere with exiftool, so you won't lose their creation time
exiftool -overwrite_original -r -if 'not defined DateTimeOriginal' -P "-AllDates<FileModifyDate" "your/output/folder/ALL_PHOTOS/""
What will be the result of using that command? Where is it pulling the date and time from? What is it doing?
