TheRiver I see no reasons why Tonfotos would not do this. The only disadvantage I can see right now is that RAW processing is quite slow, so you might need to be patient during initial indexing. Apart from that, it should work just fine. Anyway, it will not hurt trying, you can start with free version and decide for yourself if you want to upgrate to full version or you may just decide to stay with free for a while, if face recognition is not your primary goal.
