I agree... total coverage from before the time that we left until we returned. Such as me running around my house looking for the one bra that I just cannot find to pack! HAHA. Those are the moments we never remember, but make the entire trip come together perfectly. Multiple photographers would be AMAZING so that all the guests arrivals and trips can be perfectly documented for them as well.
I would also love to have unlimited retouches and effects on the photographs, all with the copyrights released to me. I love the photoshopping that I've seen on a lot of photographs. The sepia tones, b&w's, and the enhancement of colors can make for BEAUTIFUL photography.
As well, I'd love professional photo books for my parents and grandparents, and FI's parents and grandparents. This was just as special a day for them as it was for us! Photo books individualized for each guest (they're arrival, photos of the wedding from angles they couldn't see from their seats, their rooms, parties, etc) would be the perfect wedding gift from us to them, as well.
I know I'm being picky and greedy here, but I would love a photographer with the capability to shoot underwater. FI and I will most likely go snorkeling and scuba diving on our trip, and documenting that with pictures seems like it would be AMAZING!
I'm sure I'll come up with more ideas as time goes on!
