Quicky question. In about three hours I need to shoot a group of 30 people, outside, bright sun, sun will be at my back, their faces. I'm shooting with a Nikon D50 and probably a 50 1.8. This is not my normal type of gig, so I'd like some expert opinion. Questions: * Would you use matrix metering, or centerweighted? * Would you use central area focusing, or matrix focusing, or doesn't it matter? Closest subject or not? * What would you consider optimum apature setting. I anticipate the group will be three or four rows deep, front to back. I'll be using a tripod, so SS is not critical above a certain point. Any and all quick but considered responses will be appreciated.
