When Day turns into Night

There is nothing in the world that attracts more photographers than sunsets.  It is known as "Golden Hour", the time of day when time seems to move a little slower because everyone just stops and stares.  But what many people fail to understand is that there is a 45 minute period of time immediately after Golden Hour known as "Blue Hour", which is just as good.. or even better in my opinion.  (Central Park, New York City)
