Photographing the Blue hour
"Many photographers pack up their gear as soon as the sun sets. However, the most magical time to make pictures can be twilight or night! Shooting at twilight and beyond allows the photographer to create beautiful story-telling imagery. Night transforms an ordinary scene into something extraordinary, providing a wonderful opportunity to expand your creative and artistic options. From cityscapes to landscapes, and from twilight to a starry sky, beautiful nightscape opportunities are limitless."
