Martin, I just did another wedding about a week ago. I did 99% reportage B&W, pushing film as needed. I did, however, need to get at least a few color shots of the ceremony itself, which was in a very dimly lit, large church. While I love ISO 3200 B&W and shot lots of it, I don't love high ISO color films, so I had to resort to my flash. I simply used a bounce flash, and bounced it off my hand. Much softer light, and no attachments and cards to fuss with. I'd attach an image, but I haven't had an opportunity to scan them yet.
