I suffered a cyber attack and lost all the metadata for my entire set of photos. I am working with a company to recover the files but need to reconstruct who is on the files using facial recognition software. What is the best software for the job? The number of recovered files is massive -- it may be about a million, including both larger RAW files and smaller JPEGs, many of which may be duplicates. The shots themselves are a mixture of portraits and action shots. I am considering using Lightroom but am open minded if there is a better software solution. I would also be interested in any suggestions on processing such a large number of files as my previous experience with LR facial recognition is that it struggles with large numbers of files that are but a fraction of the challenge I face. Of course, I understand that to prevent future such attacks requires better security software and backups, and have already implemented these changes. I would really appreciate any help you could provide with this challenge.
