I agree with Paul, and would like to add that the Photoshop RAW
converter can rebuild a bit of the highlight information as long as
all three channels aren't completely blown.

So, if you're only a little overexposed, chances are you've preserved
a bit more detail in the shadows and may have a better overall
exposure.

It would be great if Pentax and the other camera companies would
publish white papers with a little more info on how the histograms are
generated.  This is the kind information that is perfect for the
support side of their web sites.

See you later, gs
