Re: DMillier ...

I accept your advice to use what works for me and I thank you for it, but I still want to understand what s going on.

With my X10, when I am in L 12MP mode, I do not have DR200% available to me at ISO100.  I have to up the ISO to 200 to get it.  Likewise, at ISO 200 I do not have DR400 available to me, I have to up the ISO to 400 to get it.

When in 6MP Medium mode, I have DR100/200/400% available to me at all ISO including ISO100.  This seems to prove to me that EXR hardware DR expansion works only in 6MP mode - which is exactly what you would expect given that EXR works by blending two 6MP images shot with different exposures into one 6MP HDR file.

Whether you prefer this or the conventional tone curve lift + underexposure that you get at the L size is a subjective opinion but the way in which the EXR mode is invoked is a matter of fact...
