Hi, I just recently picked up a Godox QS400 for my studio. Previously I was using just speedlights for all my off camera flash portraits. I soon realised that leaving my camera settings on "Flash" white balance gave less than accurate colour rendition. I decided to do the PRE Preset manual white balance from a photograph of a white sheet of paper.

My question is this, do I have to make a manual white balance every time I move the strobe into a different positions or can I just leave it on the one preset photo taken?. Also what if I change the light modifier to a different softbox or increase/decrease the strobe power?

I'd appreciate any help you experts can give me.

Much thanks,

Sam
