The cow eye, which is very similar to the human eye, helps to better understand howthe human eye work. This experiment tests wheather or not using a cow eye lensaffects the quality of a photograph when using a pin-hole camera. Along with testing the the effects of the cow eye lens, this experiment tests wheather or not a cow focusses better than a camera.

To test this problem 4 pin-hole cameras were made out of Quaker's Oatmeal cans. A cow's eye was dissected and the lens was removed. The lens was placed in a box filled with Bausch and Lomb's contact lens saline solution. The box was thenattatched to the pin-hole. To test wheather or not the box made a difference in thequality of the photograph, an empty box was attached to another camera and a box filled with Bausch and Lomb's saline sollution was attached to another camera. One camera was left empty. The camera's were loaded with enlarging paper in a dark room. The cameras were taken outside and a display was placed 5 feet away from the 4 cameras. The film was exposed for 30 seconds. After the thirty seconds were over, the cameras were taken back into the darkroom and the film was developed using Clayton's developer and rapid fixer and water. Another set of photographs were taken and developed. The negatives were observerd and conclusions were made.

The negaitves of the pictures taken with the camera with just the pin-hole turned out clear. The objects in the picture can be clearly identified. The negatives of the pictures taken with the camera with the just the transparent box turned out kind of blury. However, objects can be identified. The negaitves of the pictures taken withthe box filled with the saline solution turned out kind of blury, but not too bad. However, objects in the picture can be identified. The pictures taken with the cow eye lens turned out very blury. Only shades of light and dark can be seen. The pictures with the cameras turned out consistant. Both photographs taken with each camerapossessed the same characteristics.
