Your correct, that's why I've been finding images where the camera was a great distance away from the source - because it greatly reduces any scaling changes with perspective. The aim is to get the camera far enough away from the sources and using lenses ideally in the 35-100mm range so that the scaling differences when the ball is within a foot of the same plane becomes basically negligible. Also, as you can see, I am making an effort to keep the ball as close to the plane of the subject as possible in every image.
