I've heard this suggestion from a few experts on White Balance and shooting RAW...
"By setting the White Balance in the camera to a selection other than Auto. You will streamline your post processing by having a static value assigned and not a different value possibly for each image. By having a static setting for all of the images in a shoot, you can simply apply a new value to all images and be on your way."
I think this is a myth and mis-information that does not help in the understanding of RAW capture and White Balance. My reasoning is that since ACR/LR (the subject by the experts and my choice) will apply a WB value when syncing that is not in anyway affected by the WB setting from the camera, whether WB is different for each image or the same makes no difference. The WB setting in the camera has no affect on the RAW capture so there isn't any change to the RAW data from the setting, if it did I can see how it would provide a more consistent set of RAW files - but it doesn't.
Frankly, I mostly shoot RAW and I always use Auto-WB when I do. I think I can sync my WB as easily as the rest. Are the "experts" correct and I'm fooling myself, or am I on the right track, or is there another point of view on this.
I apologize if this has been beaten to death in other threads, I did do a search and did not find anything substantive.
