Does overexposing help get a better RAw file in the OMd?

Good stuff. Once one does some experimenting with their camera with some particular settings and indicators used, and gets a good feel for how to read and use the preview/review/playback indicators, then they are better able to give it a go in the field. (For me), capturing "keepers" for processing is rare enough that I then go with the best that I have captured.

RawDigger and my GH2 UniWB configuration (after a fair amount of familariziations and experimenting having taken place), usually keeps me from overdoing it on RAW levels. Unless the image seems visibly plagued with blown highlights, I tend to just process what I have at that point. I will at times check out the levels in RawDigger after the fact, but I guess that my point is that the idea is to learn your equipment and develop a technique - and then "go for it" and "carry on".
