I find the family photo part of the day can be quite stressful. People are going everywhere, you’re unaware of the different family dynamics at play and people are in a ‘festive spirit’ (and have often been drinking a few spirits) to the point where it can be quite chaotic. Get the couple to nominate a family member (or one for each side of the family) who can be the ‘director’ of the shoot. They can round everyone up, help get them in the shot and keep things moving so that the couple can get back to the party.
One thing that I’ve done at every wedding that I’ve photographed is attempt to photograph everyone who is in attendance in the one shot. The way I’ve done this is to arrange for a place that I can get up high above everyone straight after the ceremony. This might mean getting tall ladder, using a balcony or even climbing on a roof. The beauty of getting up high is that you get everyone’s face in it and can fit a lot of people in the one shot. The key is to be able to get everyone to the place you want them to stand quickly and to be ready to get the shot without having everyone stand around for too long. I found the best way to get everyone to the spot is to get the bride and groom there and to have a couple of helpers to herd everyone in that direction. Read more on how to take Group Photos.
The ability to bounce a flash or to diffuse it is key. You’ll find that in many churches that light is very low. If you’re allowed to use a flash (and some churches don’t allow it) think about whether bouncing the flash will work (remember if you bounce off a colored surface it will add a colored cast to the picture) or whether you might want to buy a flash diffuser to soften the light. If you can’t use a flash you’ll need to either use a fast lens at wide apertures and/or bump up the ISO. A lens with image stabilization might also help.

Show them your work/style. Find out what they are wanting to achieve, how many shots they want, what key things they want to be recorded, how the shots will be used (print etc). If you’re charging them for the event, make sure you have the agreement of price in place up front.
One of the great things about digital photography is the immediacy of it as a medium. One of the fun things I’ve seen more and more photographers doing recently is taking a computer to the reception, uploading shots taken earlier in the day and letting them rotate as a slideshow during the evening. This adds a fun element to the night.
One of the challenges of weddings is that there are often people going everywhere – including the backgrounds of your shots. Particularly with the formal shots scope out the area where they’ll be taken ahead of time looking for good backgrounds. Ideally you’ll be wanting uncluttered areas and shaded spots out of direct sunlight where there’s unlikely to be a wandering great aunt wander into the back of the shot.
