I have a wedding this Saturday. Our weather has been a little strange and I’m unsure about the light situation. The wedding has been put back to 4pm and the light starts to get low from about 4.30pm. I have a 70-200 F4 (non IS) and an 85 F 1.8. The wedding is outside and the sun will most probably be going down to the side of the couple. My question is what would be better, flash or higher ISO? I have an external flash for the 30D and I will have someone taking backup photos with a nifty fifty. Which lens would you go with? The zoom or prime? I am likely to be shooting handheld and have good technique. Sorry if this post asks so many things at once but I’m getting nervous. I have done weddings before but generally I have not been challenged by lower light conditions
