When doing a studio shoot; once you have your flashes positioned to give the desired light/shaddow for what you are taking and....
Lets say with room lights on and maybe an open window.
If you have set your CWB to the flashes.
Do you close the window and turn off the room lights before the shot.
Not so much as to reduce the influence of the added light; rather than to avoid the colour it will effect of the CWB.
Or, do you leave the other light influence as is and post process it out ?
I hope this question makes some sense
