I'm surprised at your tactics, Wedding Photographer, seems pretty dishonest in a church but if your clients are happy with it...
Anyway, CC, I really sympathise with you. Getting married in a church was very important to us and getting married in OUR church was even more so. We feel welcome within that community, have built some fantastic relationships with those who worship there and wouldn't have had it any other way.
Great photography was also very important to us and we almost came up against a similar issue. Our vicar had told us that our photography would be very limited in terms of what he was prepared to allow our photographers to capture. His reasons (and this is why I'm pretty surprised at Teehee's swipe at your vicar) were that
a) he wanted members of our congregation to be there to witness our ceremony and to be a part of it - he didn't want them to be glued to their cameras, seeing the service unfold through a lens. He wanted us to feel like they were all there supporting us and to remove any potential pressure of feeling like we were performing, rather than making the most solemn of vows. Pretty honourable, I thought.
b) he had also had experiences of photographers getting in the way, using flash etc and it's disruptive for everyone. He wanted to be able to concentrate on us, and us on him, without someone's movement catching our eye. Again, another fair point.
We explained to him how important it was to us for those images to be captured and promised him that we'd picked decent, experienced and fair photographers who wanted to get great shots, but not at the expense of interrupting our service. Also, assuming your photographer is decent (and from what you've said, they are) they won't be using flash. I also know that David, Teri's husband, made a point of discussing this with our vicar when he arrived at the church, which was supported by my husband. Our vicar was happy for them to be situated as Teri has mentioned above. Sounds as if we're going to get some great shots and we have a very happy vicar who's faith is restored in photographers!
