If there is an issue with sensors and meters picking up ambient light and affecting a shot (too dark or washed out) then using a flash in manual mode may be the easiest option. For candids where you're working with a consistent distance from the subject this can work. If you have a high-output flash unit (GN120 or greater) there's often enough reflection around the room that the flash's coverage resolves and ambient light issues and greatly reduces the possibility of errors in exposure.
I know a number of wedding pros who do this -- maintain a consistent subject framing (which providess a consistent camera/flash- to-subject distance) and then they don't worry about sensors and meters. Sometimes all the technology available just turns a simple matter into a complicated one. Collin
