This is the complete opposite of a fast shutter speed because this lets more light in and that causes fast moving objects to blur out. i personally don't like this type of photography because it is hard to get a good subject to focus on. in this photo the subject is a girl as a train passes by. this could be hard to get if there is eavy traffic on the train platform and if the subject moves. it could also be hard since the train only passes once so the artist must know the right exposure to take in order to get the proper image.
