If you take a brief look in manual - http://www.fdrtools.com/eng/manual/fdrtools_2.2/nav/tutorial_ii.htm
- you will see, that this is an intermediate result, without any manual optimisation. You should have a look in the icon bar and switch to Tone Mapping, as this is the typical step which needs some refinement.
If you process an image set for the first time, the standard TMO is Simplex. If you are working with the Advanced version switch to Compressor and if you are working with the Basic version switch to Receptor.

The lower left point of the line or curve corresponds to the black point and the upper white point corresponds to the white point. First you should change these two basic points of the line according to the signals you see in the histogram. The resulting line typically should be like this one:
This curve might be refined for global contrast optimisation, but here some further knowledge is recommended.
Then you should press on the Save button and export the tonemapped file.
Hope this helps. All the best
