I have had a consistent white balance issue with flash photography. This occurs with indoor flash only. I have had beautiful results with outdoor flash photography. With indoor photography I get results like this shown in the link. It is absolutely horrible and wholly unacceptable and I am hoping it is a firmware issue. A couple of points:
1. There is no possibility of color cast. The walls were white and the backdrop is black.
2. The lighting was provided by Yongnuo 560 speedlite and a Godox EX 600 strobe.
3. The white balance was set to auto evaluative. I later set it to auto and then at 5000k and the results were similar.
4. This is not the only venue/lighting set-up where this has occurred.
5. I have seen similar results using the tungsten setting under tungsten only light - no flash - in which the yellow/orange cast is horrible.
6. I cycled through other WB settings in camera and none of them resolved the color cast.
7. I have had no luck removing it in Photoshop.
