Just a few further thoughts.
Jase I also should mention that your camera has 16 bit dynamic range ie 65K odd levels whereas my Canon sensor is limited to 12 bits ie 4K levels by the A to D converter. To get the same dynamic range coverage with the Canon sensor as your camera I would have to take at least three images two stops apart. That is why I have been trying EasyHDR.
This of course assumes the target has this high dynamic range to make it worthwhile.
I think the real problem is trying to squeeze either 12bit or 16 bit linear information into an 8 bit log jpg and have the intensity distribution match our eyes logarhythmic sensitivity. All the while maintaining or attaining colour balance! This is what image processing is really about!?
