I have started thinking/experimenting with motion blur. In my animations, I have tended to have slow moving objects and the equivilent of an ultra fast shutter speed. Thus, no motion blur. But in the real world, real camera are able to record this blur.
Would I be correct to assume that operators do all they can to avoid motion blur, knowing it can be artificially added afterwards. And that guaging the level of required blur at the time of shooting is almost impossible?
