A unique stage in the progress of photography is the discovery of the pinhole technique. The history of the pinhole technique originates from observations made by Aristotle in the 4th century (Chernewski 2010). This philosopher was known for writing about his interpretations regarding pinhole photography. Following Aristotle's observations, the philosopher Mo Ti conducted experiments aimed at researching the properties of light. Mo was able to determine that light travels in a straight line (Grepstad 1996). After discovering that light travels in straight lines, Mo was able to record the formation of an inverted image with a pinhole camera (Grepstad 1996). Although Mo was able to understand the pinhole technique, it was not until the 16th century that Leonardo Da Vinci was able to provide a clear description of a pinhole camera (Chernewski 2010). The end result of these philosophers' experiments was the development of the pinhole technique using a pinhole camera. They were able to create a new method where people could capture images through photography. After analyzing the history of the pinhole technique, the next step is to understand the description of a pinhole camera. David Balihar refers to a pinhole camera as a simple optical imaging device in the shape of a closed box or chamber (Balihar 2013). The pinhole camera is different from most photographic devices in that it uses a lens. Additionally, a pinhole camera has an infinite depth of field. To explain further, most cameras have a limited depth of field and must be adjusted for an object to come into focus. With a pinhole camera, all objects in the field of view are in focus, regardless of distance. As previously stated, this is... half the paper... I conducted my own analysis on the effects of changing the aperture size for a pinhole camera, the instructions called for four or five small holes to be drilled into the piece of aluminum foil. Each hole should be similar to the original pinhole size. I made sure each hole was well separated from the original hole. When looking at the image of the light bulb, more light rays could enter, resulting in an increase in the brightness of the image. Also, the image came back right side up. For the final section, I'd like you to take into account that when I changed the size of the opening, the piece of aluminum popped out of place. I didn't have time to make another camera with other endings, so I decided to send a photo of the camera before the changes. I hope my report is sufficient to prove that the camera worked during the development of the project.
