The one step I am missing in the RAW -> HDR -> Tonemapped Output of qtpfsgui is correcting the white balance of the tonemapped output. I would like to see a pipette, like in RAWstudio http://rawstudio.org/svn/rawstudio/trunk/, that samples a 3x3 area under the mouse and adapt white balance of the image so that the sample result in a shade of gray.
