Duplicate Image advice, s'il vous plait

Hi everyone, I am quite the noob when it comes to photo organization. I just completed a several month vacation, and realized that I had unwisely not set the date the day I acquired the camera used. There are many dup detectors online, but I do not know which one to go with to use on my precious photos.... given that quite a few pictueres have the same name but are different images. Could someone please recommend a software that identifies duplicates images by 100% visual similartiy? I think it's called EXIF data it compares? Thanks in advance.
