The Window Is the Eye to the World 2b
I liked how the window light just glowed in the nearly pitch dark recess, so I took this photo to show the light. The face of the arch was pitch dark and the wall on the right is pretty much Zone 1 (nearly pitch dark). If it wasn't very overcast that day, the window light would easily overblown in the final photo. Fortunately I brought my tripod with me so after some adjustment (I found it's best shooting around about a little more than 2 feet off ground) here it is. The dirt on the window, if I am not mistaken, is actually red colored "green algae." There are plenty of them growing on Fort Point's walls. Post-processed to reproduce faithful color to my naked eyes.
