Camera Obscura Adventure

The principles behind camera obscura are surprisingly simple, but still manage to amaze viewers. The experience of seeing an image take shape in a pitch black room right before one's eyes is actually quite stunning. The light, coming from the outdoors, passes into the dark room through a minuscule hole and creates an upside-down image on the wall. It takes a few minutes for the human eye to see this, but after about five minutes, details of the outside world begin to appear. Since the image is upside-down and monochromatic, the experience is very trippy and surreal. One can feel their pupils and retina working to perceive the image, and this is almost psychedelic in nature. It is refreshingly to know that a simple ray of light shone through a mere pinhole can cause such an interesting phenomenon. Literally and figuratively, camera obscura is an eye-opening experience.

Sunlight from the outdoors isn't the only way to witness camera obscura. Well-illuminated indoor objects can have the same effect. For example, a still-life setup looks very dramatic when viewed in a camera obscura booth. At first, not all details are apparent. Vague shapes take form first. The most recognizable object was a model of a human hand. Next to it, there appeared to be several blobs taking shape. From what I perceived, two shapes were rectangular, one was globular, and the last was bottle-shaped. After leaving the booth and viewing the still-life, I realized that there were more shapes that my eyes hadn't detected. One was a cylinder, which I had mistaken for a rectangle, and another was a small sphere resting beside the hand. Had I stayed in the booth longer, these shapes probably would have become more apparent. For the most part, I managed to make out many of the major shapes.

A Landscape at Three Different Times in One Day





At mid-day this small building, containing electrical equipment, stands like a miniature castle in a public park. For the most part it is very well illuminated, however the sun's angle causes the facade to remain in shadow. The quality of light is very crisp, since this is the brightest time of day. Snow on the ground reflects sunshine, but because it's melting, most objects appear to have a wet sheen. The space is inhabited by geese and ducks that live in the reeds nearby, and walkers strolling through the park. There is moderate vehicular activity on this street, with a few cars passing every minute.

At sundown the park grows dark, but a timed light on the building keeps the entrance illuminated. There are too many trees and large buildings in the area for the sunset's orange glow to reach the park, but streetlights keep the surrounding area lit with a blue fluorescence. At this time of day, no one is in the park. The only signs of activity are cars going down the street, and the occasional jogger running by.

Once the sun has set, the park is pitch black. The main part of the building is almost completely in shadow except for the light above the entrance, which illuminates the short path leading up to it. Another timed light towards its rear illuminates that section. Streetlights cast a glow over the street where mainly taxicabs roam. Hardly any human activity is seen.

The most interesting time to view this area has proven to be mid-day, when there are people and animals inhabiting the park. I would describe the area to a blind person as a place of activity. Even without sight, one can sense the goings-on. The sounds-- people strolling and talking, geese honking, wind blowing, cars speeding by--as well as the wet sensation of the melting snow, all contribute to a feeling of activity made evident through the passage of time.

Ancient Egyptian Timekeeping: The Water Clock


The ancient Egyptian civilization, first springing up near the Nile delta around 5000 BC, had a very substantial understanding of time. It was the annual flooding of the Nile River that influenced ancient Egyptians to begin to record time. They needed to record time in order to determine when to plant and when to harvest crops. This relationship between the ancient people and nature reflected their spirituality, since they viewed the Nile as a pathway to the afterlife.
Ancient Egyptians used sundials to observe the 12 daytime hours, but in oder to tell time at night, a new method was needed. Under the reign of Ahmenhotep I, a man known as Amenemhat created a water clock. The water clock, also called a clepsydra, was a essentially a funnel made of alabaster that stood about 95 centimeters high. It had 12 sections carved into it, each with 11 perforations lining it. When filled with water, the clepsydra would take 12 hours to drain through a tiny hole in its base. To tell time, one had to observe the water level in the clock, and read the time according to the closest perforation. The timekeepers were priests and astronomers, who needed to know when to plan religious rituals, which were of utmost importance to the ancient civilization.

James Turrell


James Turrell's fascination with the influence of light on the human environment is the subject of much of his art. Turrell's ambitious crater project, started in 1972, is an attempt to immerse people in his grand vision: bringing the cosmos down to earth, and giving people a true sense of existing in time and space. This is an impressive undertaking, and an important one. In today's world, it appears that mankind has lost its connection with nature. Turrell's exhibitions allow people to enter atmospherically lit spaces where various illuminations influence behavioral and emotional states of viewers. This allows people to rekindle a relationship with nature, and experience interactions with light and time that they may take for granted in daily life. Stepping into Turrell's crater, one can feel the passage of time and earth's movement in space. Human life in the 21st century seems mostly disconnected from nature, and Turrell has effectively brought back to mankind these cosmic interactions.
