Alex,

Here's a comparison between the two. I turned around and looked at the guitar, and the libraw result is truer to the actual colors of the instrument than the lightroom first-pass rendering:

Alex, I suggest you add these to your example on the API intro page:

// Convert from imgdata.rawdata to imgdata.image:
// ----------------------------------------------
iProcessor.raw2image();
iProcessor.imgdata.params.use_camera_wb=1;
iProcessor.subtract_black();
iProcessor.dcraw_process();

Kudos. Fine work you've done. :)
