This is going to be a fun one.

Small church, cross shaped. Unfortunatly it is rather narrow, and benches goes all up to wall on both sides, preventing much moving during cermony.

I havnt spoken to the photographer yet, but I guess it will be something like being up at the altar when bride walks down, then step into one of the T 'niches' as she passes by, and then move back to the rear and put up a camera there.

For the wows perhaps walk down back to the 'T' and run back for the walk out.

I'll try set up a camera high from the back to cover the altar at all times.

Can be a bit tricky to capture the guests, perhaps run down to altar once during a hymn to try get some :) Or as far as I understand, there are doors on each T section, perhaps I can use this as secret passageways and run back and fourth outside the church. hehe

Anders, may I suggest you have a read of the thread near here addressed to "high-end pros" - one of the most important piece of learning is that brides like discreetness. Unless yours are very different in Norway, I'd keep that uppermost in mind as you work. Running around the church isn't discreet.

In the UK more and more vicars and not a few Registrars are stopping movement altogether and restricting the ability of the photographer and handheld video people to turn the ceremony into a version of a studio.

In the context of what you wrote (and perhaps admire) the question is a non sequitur - you're not placing your cameras at all.

Just for the record, our are two in or near the choir pews at the front with an eyeline to each the bride and the groom, and a third camera radio on a hothead all radio controlled, on a 14ft tripod at the back of the church.
