I've used an app called PhotoSweeper[1]. It can access your Photos library directly. You can manually review them side-by-side or let it run automatically. You can also set thresholds of % similarity to reduce false removals. I believe it can also move the duplicates into a separate album for review later. https://apps.apple.com/us/app/photosweeper/id463362050?mt=12 https://apps.apple.com/us/app/photosweeper/id463362050?mt=12
