I shoot only in LiveView and almost always use center-weighted averaging metering. I want a Canon Rebel T3i, however, in LiveView the camera defaults to Evaluative metering. My question: If I am shooting entirely in Manual, does the Evaluative metering really make a difference? When I pose this question to Canon -- and I have on a number of occasions -- I get mixed answers. Some tech support folks say yes, others say no. I use center-weighted average metering because I primarily photograph seated elderly people against a black muslin background, and I don't want the camera to try and lighten the background. Thanks in advance.
