Here’s another photo I took in Tiburon, California. It’s of the west side of Corinthian Island. I took this photo during the evening blue hour. The blue hour is my favorite time for landscape images. The evening blue hour begins a little after sunset. There is a blue hour before sunrise as well. If I were to shoot the island’s east side, I would shoot it before sunrise.
According to Wikipedia, the blue color spectrum “is most prominent when the Sun is between 4° and 8° below the horizon. When photographing during blue hour it can be favorable to capture subjects that have artificial light sources, such as buildings, monuments, cityscapes, or bridges.”
While I’ve never timed it, my recollection is that the blue hour starts about 15 minutes after sunset and fades away 30 to 40 minutes later.
