Mike,
I'm like you... I'm more into landscapes than people, and I'm no pro, but I have a brother who is
.
What time of day is the wedding? Where you practice shots taken the same time of day, so you are confident you won't have shadows on faces and won't have people squinting into the sun?
I know you've said you expect not to have to use a flash, but I'd recommend if you have a good one make sure you take it and have plenty of batteries - a bit of fill flash will do wonders in a backlit shot or if you get high contrast or shadows on faces.
Having H along as well is a great idea.
I have photographed a few weddings (not as
the official photographer
) and it's good to work as a team.
While one is capturing the formal shots, the other can capture less formal and behind the scenes shots that often end up as some of the great memories. The little things like decorations, flowers, gardens and features around the wedding that everyone will have seen, and even some "papparazzi" shots of the photographer taking the formal shots seem to go over well.
It's not just about the people or the scenery but trying to pick up the "memories" too.
It looks like you're setting up with some great landscapes in the background of the shots, but don't forget to try to get some tight ones as well with nothing to distract from the people.
Most of all have fun, so the wedding party has fun and don't miss any candid shots if they have a bit of a play - they can often go over well too!
You probably know all this anyway... but I hope its worth somethign to help you on the day.
Lets see a check list...
Batteries,
backup camera(s),
Lenses,
tripod ? (for some more creative shots, perhaps? Say a story panorama? e.g. bride and groom in separate shots "noticing" each other, next shot together with perhaps a kiss and the last shot walking off hand in hand, perhaps, all in the one final shot.
Fiddly to do, but can be a lot of fun and be very effective if done well).
More batteries,
Spare memory card (my experience is if something can go wrng it will!
),
Good strong flash with more batteries (for fill flash, or just in case...)
Sense of humour,
more batteries...
I'm sure you've got the message!
Al.
