Thanks shinnya & Kerik. I will be in San Francisco in the middle of this month. Not sure if I'm able to travel to those states to view them. You know I just bought an old copy of Photographer of the Majesty, Light and Space of the Medieval Cathedrals of England & France. Even though the print quality isn't ideal, I am completely blown away. The precise camera positions, the lighting, space, etc.. Wow!
