having no experience of Fuji cameras until the past week, I don't understand the fundamental principles of Fuji DR100/200/400. I know what's it's trying to achieve, but how is it doing it? Please feel free to point me to where this is all explained if you can.

Here are some links:

Explanation by DPReview's Richard Butler(Trevor G calls this technique, deliberate underexposure plus alteration of the highlight end of the tone curve, "EXR processing" -- but Fujifilm does not -- because the current generation of CPU in all of the high-end Fujifilm cameras, both EXR cameras and non-EXR cameras, is called "EXR Processor II.")  Some Canon cameras perform the same software trick and call it "i-Contrast"; for some reason Canon does not call it "EXR processing," either.  

The same Richard Butler wrote a detailed explanation of EXR-specific dynamic range enhancement in his review of the first EXR product, the F200EXR, here:  How EXR achieves DR enhancement.  Here are Fujifilm's own explanations of EXR:  "What's EXR?" -and- "EXR Technology: Wide Dynamic Range".  Fujifilm EXR cameras -- that is, cameras with EXR sensors -- can use the software version of dynamic range enhancement technique on top of the EXR hardware dynamic range enhancement, whereas the X100, X-Pro1, X-E1, X-M1, and X20 cameras are limited to the software dynamic range enhancement technique.
