I'm helping a friend shoot for his wedding, but I have little experience with flash photography for such events. I've got a Canon 10D and Speedlite 420EX w/Omni-Bounce (the white covers that goes over the flash).
Whats the best setting to use for such events? Do you go with with Shutter Priority, Aperture Priority or Manual.... and how should I set it? Also, should I go for direct flash, or use the omni-bounce? (assuming there's a high ceiling)
Any advise will be appreciated.... dun wanna screw it up for my friend on his big day....
