(Sony DSC-R1; 1/640 sec.; F 8.0; 160 ISO)
One of my favorite task in photography is to find abstract details in the architecture. I consider that the black and white is a format well suited for this purpose. In this occasion I share an abstract based on windows and balconies of a modern building in Barcelona.
This is my first entry for the photography contest B & W Photo Contest -- Architecture ran by @daveks and sponsored by @papa-pepper.
