Another Flash experiment (Slow Synchro)

This experiment reveals why to use slow synchro.
The first image is a no flash click, see the details in the background having prominence.
The second is a flash click. It darkens the background and lightens up the subject.
The third is the slow synchro. It is a long exposure shot, for the first part of the exposed time there was flash fired and the later the was without flash. This combines the both the effects of flash and no flash. Use this method to get stunning portraits at night.
