this shot can be done very easily, you can very the distance of father/baby and the camera to get the degree of blur you want, eg, want more blur, move father/baby and camera away from the background, less blur than move closer to mother.
these kind of shots was commonly seen on traditional pose wedding portrait in the west, is a must have shot, where focusing on the bride, and parents of the bride pose at the background looking at the bride, in defoucs.
btw, it is a set up shot, it does not happen naturally.
hi, pardon me as a newbie, as a layman, if i see in the view finder, the focus sq is pointing at the baby for the shot? not at the man or in between the man and the baby?
thanks
