JavaJones: I'm really struggling to understand the justification for a book module given the response to the face recognition issue: "'Face recognition is very important to some', he says, 'but irrelevant to others.'" So, kind of like a book module then?
I'd be shocked if making expensive photo books is more popular and of greater interest than face recognition, which can be useful to *anyone* who takes photos of people Anyone who says they have no use for it is likely to change their mind if they get a chance to work with a *well-implemented* system.
If Adobe is thinking about professionals and their cell phone pics with the geotagging module, clearly they're not so concerned with targeting a minority of the market. How many people are really editing their *cell phone* pics in LR?
My guess is they made a deal with Blurb, let's say 15% of all revenue from books made in LR4. Blurb gets promotion, Adobe gets extra cash. We get a module useful only to a minority of people. Win!
Their original audience is professional and advanced amateur photographers. I'm more likely to produce a book for my clients than to spend time tagging the names of all of their guests at a wedding or event, the first situations that seem likely to benefit from F/R. Producing a book layout within LR is much easier than InDesign, especially if the client wants to play "what if..." with the layout. Having said that, if a client wants me to tag all of their guests' faces, a reliable algorithm would save them a lot of money (and save me time) - I don't get a sense that the technology is there yet. I recognize that for some F/R is more important. For my work, Book is a better feature.
