I'd never seen Jeff Ascough's wedding photography blog before. It's worthwhile—well-written and thoughtful, and Jeff obviously knows what he's doing. Here's a nice piece about shooting weddings with a telephoto lens. You might not agree with it, or all of it (I hope I don't just post links to things I agree with...), but it highlights the fact that a lot about shooting technique has nothing to do with the photo-technical aspect:
Being unobtrusive is largely about behaviour, rather than dressing in black and trying to blend into the shadows.
What people do find uncomfortable, is the idea that they are being 'spied on.' Standing away from a group of people at a drinks reception, and pointing a large telephoto at them is far more suspicious in terms of behaviour, than being in and around them taking pictures. Guests can't see the photographer's face, and non-verbal communication is missing. This can lead to a degree of discomfort and a change in behaviour patterns, which I believe leads to poorer pictures.
If I were a wedding photographer I think I'd bookmark that blog. Sometimes I think that the highest compliment I can pay another photographer is to say he's a good shooter. (Or she.) And good wedding photographers are good shooters, for sure.

Featured Comment by hlinton: "I'm kind of on the fence about this. Having shot events and weddings (and other assignments) all over the world I don't think one can limit themselves to just this or that approach. At times it works but as times change so do the processes. I use three zooms ranging from 16 to 200mm. Can't go anywhere without them. I was beginning to think that I never shoot anything wider than 28mm only to discover while shooting a party recently that I would have been in big trouble without the wider zoom. By the end of the night everything was shot on a 70–200. I really think it comes down to personalities. Jeff attracts the type of client that he shoots best allowing him to utilize his skills in a way that's appropriate for him. That's not to say that I don't agree with him. I just think that we all get to where we're going in our own way and his way may be (and most likely is) different than your way."
