Niether, Amita. What the meter does, is to try to reach an exposure, that in average give you the same "brightness" as a grey card (18% reflection). Matrix metering, however, can furthermore help to illuminate the impact of a very bright sky i.e., which would normally cause under exposure.
In extreme situations, like the snowy scenery, only your own judgement is good enough. After all, the camera doesn't know that it's snow, just like it has no way of knowing whether you are photographing a white horse or a black bear! You have to know! When the camera sees a snowy scenery, it really "believes" that it's very bright, then stops down to get "normal" brightness of the scenery. Thus rendering the white snow as grey, due to under exposure. I agree that the LCD is a brilliant tool for judging exposure. It difficult to identify burned out highlights, though.

While I was out, I switched to manual and got the right settings through trial and error. Thank goodness for the LCD screen! So which is better on the istD in the snow, center weighted or spot metering? Or should I just learn to eyeball it? Thanks, Amita
