I just listened to it in its entirety, and it was one of the better shows I can remember lately. I had never heard of David Ziser before the show, so thanks Gavin for introducing me to his work; there's a lot to learn from him!
It was interesting for me to hear him put it as simply as "future feelings." We all know that it's really a brides (and grooms, to a certain extent) connection to the photographer that gets us the job- and by having her think about how she will FEEL in 5, 10, 20 years is almost a no-brainer.
The Wedding season in the Southern Hemisphere is coming to a close, and like most wedding photogs now is the time I start thinking about where I want to go before next season, and how i want to get there. This last show made me think, and now is a good time to start think about things like that.
Oh, and i'm glad the Apple/iPad geek out segment was saved for the end
