I appreciated the Allegory of the Cave reference that Plato attributed to the “unknown”, and the way it caught my interest as a chapter opening. The common theme in the reading, that light is mysterious and partially a void, reminds me what photographer Diane Arbus stated, “A photograph is a secret about a secret. The more it tells you, the less you know.” This mysterious quality to light and shadows is so intriguing, and has kept our interest since photography’s beginnings. I like what photography historian John Bloom wrote about shadows, saying “…Belief in their magical powers was connected to their sun-origin and their ability to evoke significant form.” I had never really thought of shadows as similar to negative space, and I found this connection really interesting. I also enjoyed reading about the typical symbolism between light and dark, the good and evil references we associate with tones.
