The adjacent picture is an example of case
2; i.e. Camera & Background (stones etc)
are steady whereas the object (water is
moving (flowing) resulting in the creamy
blur. Though this is blur, it is used
creatively & taken to advantage to show
the flow of water creating the illusion of
motion.
The picture below is an example of case 1,
where the object & the background are
steady. Here the street lights are glowing
steadily but the camera is waved zigzag to
create the waves of lights. Simultaneously,
a fire cracker is seen captured within the
waves giving it the illusion that, many
fireworks are taking place together.
In both the cases we see that the slow
shutter speed used effectively creates the
pictures of unusual look & makes the
viewer wonder, how the picture is taken.
