Hi Chad,
with all that white in a room like that it would have been impossible to get an acceptable result with my camera which is undergoing an RMA.
I downloaded your image and did a quick neutralization of the white background. I was going for a clean white not a natural warm white.
It was impossible for me to achieve an acceptable result with temperature sliders only. Which is alway going to be the standard by which I measure. However, resolving to using a more advanced technique involving alteration of the matrix and thus inevitably a slight shift in color representation/saturation - was able to neutralize for a clean white background.
Now, I am NOT able to achieve a remotely similar result with my camera which HAS been labeled "RMA" and while I was not present in that room I have no idea as to whether the colors are off. However, while the results in the initial frame were exhibiting a magenta color cast - on a Matrix level it was possible to neutralize.
On a second note, I don't think people should have to resolve to matrix ops. to be able to de-cast an image. But those are two diff. topics.
1 - being an impossible to remove non-uniform lateral color shift: Hardware Issue
2 - being a possible to remove uniform color cast: Software Issue (Matrix Calibration)
Prior is an RMA case - Latter is a firmware fix.
First image is normal second employs a power function which should (if present) reveal any hardware non-uniform issue.
