Does the non intrusive photo-journalistic approach in wedding photography really work?
I've been doing a fair bit of research, and I don't see the top photographer taking that approach and I personally can't get anything useful without getting involved.
I understand that at the ceremony and the reception you need to step back and let things happen. But saying that, I still give them some instructions prior to the event.

(I'm not sure if this is the right place to discuss this point. Please advice if it isn't.)
