The Greek origin of the word Photography is roughly "Drawing with Light". In modern parlance I'd say that translates to:
"A Photograph is Only as Good as the Light it's Capture In"
This is the reason why Twilight images are so successful in showcasing the fundamental beauty of the architecture and landscape of a home or business. The ethereal quality of the light just before sunrise and after sunset simplifies the composition down to the essential shape and form of the Architecture. For the Real Estate Photographer, Twilight Photos are considered "money shots" and often become the lead exterior image.
