#lightandinteractivity #itp . Gramercy Tuesday, February 19, 07:56-10:34 . This is a time-lapse video taken at 2 frames per minute at 480p resolution. The video here is played at 70% rate for better observation. . This video is taken facing north. As the sun rises on the east side (right side of the video) the shadows change in many ways. Earlier in the morning the shadows are longer, more stretched, more blurry and change at a much faster rate. In contrast, later in the morning the shadows are shorter, more compressed, sharper and change at a much slower rate. . The angle of the sun affects the qualities of the shadow hugely. When the shadows become sharp, they almost create another dimension to the balconies with their geometric forms. It is as if the building has a separate physical presence outside of its actual bricks and mortar.
