Health Care Forum - Manual Metering

Everyone's getting into the health care debate. Here I was covering a forum mediated by Wolf Blitzer, Including Sen. John Barrasso, M.D, E.J. Dionne Jr., Judy Feder, Charles Krauthammer, and Rep. Stephen Lynch.

In situations like these, when the light will be constant it's ALWAYS best to shoot in manual exposure (some people disagree on this topic - just my opinion).  Set your manual mode for correct exposure of their faces, then no matter how you're zooming around everything will be fixed (assuming you have a constant aperture lens).  Otherwise the size of the bright faces compared to relatively darker backgrounds will change, fooling your camera into thinking the amount of light has changed and therefore varying your exposure.  Here's a good article on the subject.
