Got a question for all you experienced photogs who shoot wedding receptions and dances. What do you do when you they are ready for you to take the important first dance pictures, and then the DJ turns off all the lights and starts the blinking colored lights with the disco ball going? My exposure meter is bouncing all over the place and I have to decide when to take the shot and hope that it turns out okay. Here is my setup: Lens: Canon EF 28-135mm IS USM f/3.5-5.6 (I dont have a lens with f/2.8 or better with a wide angle) Mode: Manual ISO: 1250 Aperture: as wide open as it will go for the focal range Flash: 580EX on a bracket pointed straight up with a bounce card on the end of it bouncing the light forward as well as off the ceiling. There is almost no room light to work with. I'm just using the flash to bounce light forward from the card and also off the ceiling. I try to do everything possible to keep the shutter speed up to at least 1/50 to 1/60 without severely underexposing the images. Some shots worked and many didn't. What is the solution here? shutter curtain sync? I am really struggling with this one. Any help would be greatly appreciated!
