K100D exposure

Can anyone tell me which are the best meter settings to help me get over the slight underexposure problems I seem to get from time to time with my K100d

Personally I would use matric metering and set the auto exposure lock to the focus point (see the custom settings). If you also use the centre focusing spot only then it's a simple matter to focus, lock with a half pressure on the shutter release and then recompose before taking the shot.

I think this might well do the trick.
