Re: Color correction, more latitude in camera than lightroom?
Larry, In the Develop module, under HSL/Color/BW, have you tried clicking on HSL, and then Saturation, and desaturating the colors that have a blue component? That's all I can think of.

Re: Color correction, more latitude in camera than lightroom?
Check out the Camera Calibration panel to manipulate the range of adjustment available in other Develop module panels. You might need a customized camera calibration profile, which you create using Adobe's DNG Profile Editor, for lighting situations which are extreme. (To create a custom camera calibration profile, you need to convert at least one PEF from the camera to DNG and use that as an editing basis. The resulting profile is usable regardless of whether you edit PEF or DNG files from that camera.)

Thanks, I'll give that a try.
