So here is the job description: To shoot many vacant interiors in a undisclosed San Francisco Office Building for a client’s lease proposal in under 30 minutes time. These did not make the client's final cut (http://bit.ly/91KZIh) but I found it fascinating how sunlight can filter/creep through the glass, walls and surfaces of the interior and create awesome gradients. Gradients are easier to see when images are set to black and white!
