My church has asked if I would shoot the candlelight service on Christmas Eve. They did this a couple of years ago, but only have a low res image to show for their effort. Now they want something better. This is a large church that seats 1,400. Flash is NOT allowed and there will be very low light (mainly lots of handheld candles). They have requested that I shoot from an upper vantage point which I am going to check out this afternoon. My equipment is a Nikon D80 and I have the following lens: 50mm f/1.8, 18-135mm kit lens, 12-24mm f/4, and a 70-300mm f/4. They want a shot of the whole church showing as many people as possible. The shooting position is near the ceiling above the altar. Can someone offer advice on lens, settings, etc?
