I have used the Agfa Portrait film in the past... I would suggest giving it a bit more exposure (rate at 100). It is a subtle and smooth film designed for large contrast ranges (bright sun or black tux to white gown). It is also very fine grained. But the subtle pallete and contrast range are it's claim to fame.
Having worked in a colour lab and having seen countless thousands of rolls of film processed, it has to be one of the best looking wedding films. If you can live with a 100 speed film (I know a lot of wedding photographers that prefer the 400s) it has to be one of the nicest out there.
