Watch for LR6 on Tuesday. It supposedly adds faces support.
That's what the rumours are saying. Now, if only there was a Places plugin, we would be all set.
By Places functionality, I mean displaying location data on a full-sized map (including hybrid streets/satellite view with location pin-drop or whatever, quick batch editing, setting, and correction of GPS and other, map-based location information into EXIF, and, quick and easy display of location during a slide show.
Why? Because I was just giving a slide show a couple of days ago and people unfamiliar with the locations in a particular country wanted to know the layout of where things were for some particular picture locations. As I keep saying, this is very basic photography, not super-professional stuff. It is very basic for people to want to see on a map where particular photos were taken.
