I've been trying out different things on my X100, and one of the things I really haven't figured out yet is metering, particularly with regards to exposure. I figure, if your scene doesn't have a whole lot of contrast, it doesnt matter much which metering mode you use (sure there'll be different outcomes, but you could always correct a little bit up or down to get the result you want). However, if there's a lot of contrast in the scene, I find that multi metering often tries to preserve the highlights, which usually aren't my subject. As a result, the subject gets buried in deep, deep shadows - but not always! Relatively minor changes in composition can swith the whole thing over to exposing for the shadows, throwing off any exposure compensation I had dialed in to correct the earlier underexposure, resulting in an overexposed subject! So, to make sure my subject is always properly exposed, I use spot metering. The downside, of course, is that this doesn't do anything to preserve highlights (or shadows), so I have to dial in exposure compensation quite often. Average metering seems even dumber than multi metering, and does nothing in particular to have a properly exposed subject, but at least it's predictable and doesn't seem to vary quite so wildly with slightly different compositions. You just have to use exposure compensation with almost every shot. I guess my optimum would be a multi metering mode that assigned more importance to the subject than it does right now... how do you guys & girls use deal with metering? BTW, I haven't really looked into the effect different metering modes have on white balance behavior yet.
