Re: A question...
I don't think there is any harm in doing photography of anyone and as you said it is not nude or exotic then why would the wife have a problem with them. And I am assuming he didn't have any sort of bad intentions, that women was just his friend so what's the big deal. If one has trust in eachother, then taking a few snaps or dining out, etc with a friend of opposite gender should not be gid deal.
