Poor raw conversion from Fujifilm X100 .raf format in Lightroom 3 and 4

Question

I'm seeing very poor results when doing raw conversion from Fujifilm X100 .raf format. Who can I contact about this? Is there anything I can do?
See below for what is supposed to be a white curtain, lit by stage lighting. It results in a blown out blue channel, serious loss of detail, and very ugly gradient.

Answer 1

The blue light is so intense that it is, or almost is, saturating the sensor.
The camera’s built-in raw conversion handles this by shifting the color to cyan—clipping the blue and allowing the green to contribute more.  I doubt there was cyan lighting in the scene, only blue.
Adobe does not shift the hue, but this makes the blue seem over saturated.  Adobe’s conversion may be more colorimetrically correct, but less pleasing in this case of intense lighting that the sensor cannot accurately record.
It is a difference in camera profile used between the camera and Adobe.  Since Adobe does not supply camera-match profiles for much more than Nikon and Canon cameras, you’re not going to be able to fix things other than managing the over-saturation using HSL or WB or other things like lower-vibrance, higher saturation. 
You could try making your own camera profile using an X-Rite Color-Checker Passport or the color-checker and the Adobe DNG Profile Editor:
