Creepy beconning, large format film photography

I really loved the graffiti in this hall, the exposed rebar and the challenge of shooting in really low light. Thankfully areas of sunlight allowed me to meter and focus so I could capture the scene. None of the blacks clipped, but the strong sunlight was too much for the FP4+ – must have been 5-6 stops brighter than my base exposure.
