Extreme violet light

 This is recreated jpeg by the camera converter with default settings, Provia film emulation and automatic WB. This is a preview (thumbnail) jpeg that Adobe DNG Converter embed into DNG files. It's roughly the same as generated by others Adobe software, Lightroom for instance, reduced to 1024 pixel width. Thus I'll show result jpeg from Adobe DNG Converter only once.
Lightroom with default settings (WB set to camera). I hope you can understand now why I am so motivated to look for a new converter. :) Lightroom with WB set to "Auto" and "Auto tone" pressed. Somewhat better, but still awful.
This is a Fujifilm official converter RFC EX. For X-E1 it automatically rises parameter DR in the highlights controller to 0.4EV. WB set to camera, EV compensation 0. RFC EX with auto correction of exposition and WB.
Silkypix DSP5.  For X-E1 it automatically rises parameter DR in the highlights controller to 0.4EV. WB set to camera, EV compensation 0. Silkypix DSP5 with auto correction of exposition and WB Auto(Absolute).
Capture One 7. First time jpeg from a converter is as good as the one from the camera.  Capture One 7. It does not only change brightness by auto correction but also makes some magic with levels. Image heavy rebuilded and lost the night charm, but still looks not bad. I say more, this is very close to what I can remember about this scene. Sure I saw all brighter, as on this photo.

Dcraw has very primitive algorithm for AWB, but it worked better than some sophisticated commercial  alternatives. But to tell the truth, the correct colour was violet but not tan.

And... I can't understand... Dcraw is a very small program written by 1 programer in free time. The program is a single file 352 KiloBytes size. Why such program show better result than programs of such huge giants as Adobe?

ISO 200 sample

Recreated jpeg with camera default settings, standard noise reduction. WB set as it was in RAF: "custom" (by grey sample) with manual WB shift R -3 B 0. The same, but with AWB setting in the camera converter. To test AWB function of the camera too. The camera raw converter doesn't have an exposure auto correction.
Lightroom with default settings. Camera WB detected as Temp 4650K Tint +63.  Lightroom with auto corrections. WB set to Temp 4700K, Tint +30.
This is a Fujifilm official converter RFC EX. For X-E1 it automatically rises parameter DR in the highlights controller to 0.4EV. Detected camera WB is Temp 5355K Tint 0. RFC EX with auto correction exposition and WB. WB set to Temp 5039K Tint 4.
Silkypix DSP5.  For X-E1 it automatically rises parameter DR in the highlights controller to 0.4EV. Detected camera WB Temp 4779K Tint 19. Silkypix DSP5 with auto correction of exposition and WB Auto(Absolute). WB set to Temp 5418 Tint 6.
Capture One 7 without autocorrection. Camera WB  detected as Temp 4549K Tint 23. There is a color moire on the engraving. It can be fixed by the "moire" tool (Amount=75, Pattern=12). Capture One 7 with auto correction and AWB. WB set to Temp 4551K Tint 20.7.

Too dark. IMHO this is because X-E1 always underexposure for 0.4EV, to get better dynamic range.

It's cold as the camera AWB, but better than some commercial alternatives.

ISO 6400 sample

Recreated jpeg with camera default settings, standard noise reduction. WB set as it was in RAF: "custom" (by grey sample) with manual WB shift R -3 B 0. The same, but with AWB setting in the camera converter. To test AWB function of the camera too. The camera raw converter doesn't have exposure auto correction.
Lightroom with default settings (WB set to camera). The denoiser isn't automatically adjusted in lightroom by default with high ISO, but you can create automatic profiles for each ISO by youself. Lightroom with auto corrections.
This is a Fujifilm official converter RFC EX. For X-E1 it automatically rises parameter DR in the highlights controller to 0.4EV. In hight ISO RFC EX automatically rise denoiser. RFC EX with auto correction.
Silkypix DSP5. For X-E1 it automatically rises parameter DR in the highlights controller to 0.4EV. In high ISO DSP5 automatically rise denoiser. Silkypix DSP5 with auto correction of exposition and WB Auto(Absolute).
Capture One 7 without auto correction. But even without auto correction it automatically changes parameters of sharpness and denoiser for the high ISO.  Capture One 7 with auto correction and AWB.

Dcraw has a primitive denoiser, but it was not used. What is interesting, that X-E1 ISO 6400 raw image can be used as is, without any sharpness and denoise. Sure, noise exists, but it is almost invisible when I look at this image scaled by image viewer to my 1600x1200 monitor. It's looked like a little grain.
