have fun?? I am losing sleep over it... I am dreaming of s/s etc...
CRAZY!!!
and this whole wb just confused me more...
I will not be using my flash if I dont have to, just too obtrusive...
If you will not be using flash, then you are in great shape. Find your dominant light source, if it's a church with a lot of window light, set your WB to Shade and forget about it. If there are very few or no windows and mostly artificial lighting, it will more than likely be tungsten. If that is the case simply set your WB to 3000K, shoot something white, and then correct everything in post in one shot like I explained above. If you really want to be accurate, shoot the altar cloth from the center isle, the left isle, and the right isle. Then in post, select all images that you show from the left isle and WB to the image you shot of the altar from that direction. Repeat for the other locations and you are golden.
As a side note, as you do more weddings try to learn the different light sources and what color they look in the camera. Tungsten is very orange for the most part but sometimes it has a bit of yellow, fluorescent looks green and it's the worse to photograph in because it give skin tones an ugly green tint. But because fluorescent is not a constant light source (unless it's daylight balanced fluorescent), if fluctuates, it's temperature changes even in the same bulb, so it's a pain in the neck to get spot on WB in camera, sometimes even putting a gel on the flash.
Do you have a link to the church that may show a picture of the interior? If so, post it here and we could better suggest what kind of color temperature you'll be up against.
