You & Your Wedding (Jeff Ascough)
What a great site! Be sure to have a look through all his galleries - Jeff shoots mostly B&W available-light with Leica rangefinder cameras. This guy is one of the best photographers of this style I've seen anywhere.
Wedding Photojournalism by Ben Eden
A very large number of beautiful wedding photographs, both colour and B&W. Ben has not just cherry-picked the best photos from his portfolio, he's put whole albums of many events online. It's easy to show 50 nice photos from 50 weddings, but to show this many great photos from each event is truly impressive. Ben's site is a must if you're into the Leica-style photojournalistic look.
