I have been looking for an answer on the forum, but could not really find anything useful.
I have a multicamera system (64 Powershot A1400) and would like to set from script the cameras to custom white balance with a specific "value" (I don't even know how this custom white balance value is stored on the camera). For my application, I don't want to shoot in raw. This would slower significantly the workflow.
I am able to set them in custom WB mode via the propset "WB_MODE", but I don't know how to specify from script the "value" of the custom WB.
Ideally, I would set the custom white balance by hand on a camera, retrieve the "value" and then set the custom white balance of the other cameras to this "value".
Thanks in advance for your help.
