Pic of a cement mill here in the western reclamation area of downtown auckland - this area is being rezoned and will be a construction site for some decades to come ...
The pic is a cyanotype contact print from a 6x7 neg - pretty small! - the detail of the surrounding tower was bleached out in the print leaving just the interior you see ... Reminds me of Lebbeus Woods' chamber:
