I need to use these images for my photography class. I am always telling the students to stay after "golden hour" when the sun goes down to what is called "magic hour". To me the magic hour is only good for silhouettes, but the general rule is to just keep staying until all the light is gone even if you think you already got the shot. This was really true because the later I stayed after sunset, the shots just kept getting better. I kept thinking I was done but ended up staying until dark. It was one of those rare times where you just can't leave.
