Help Request - Compare Images using EXIF Date

Hello Scripters,

I am trying to identify duplicate images. I understand the basics of comparing one file to another using something exiftool. However, I am having trouble taking this concept to next level. e.g. searching within folders, looping, etc.

Folder 1: 1000’s of images from the whole shoot.
Folder 2, 3, 4, etc: Groups of 20-30 images that have been exported and renamed from the original set in Folder 1.

Select reference folder.
Select duplicates folder(s).
Label matches in reference folder.

Any advice to help point me in the right direction would be much appreciated. Many thx.
