Pinhole Photography! XD

Photography

Photography is the process, activity and art of creating still or moving pictures by recording radiation on a sensitive medium, such as a photographic film, or an electronic sensor. Light patterns reflected or emitted from objects activate a sensitive chemical or electronic sensor during a timed exposure, usually through a photographic lens in a device known as a camera that also stores the resulting information chemically or electronically. Photography has many uses for business, science, art and pleasure.

Camera

A Camera is a device that records images, either as a still photograph or as moving images known as videos or movies. The term comes from the camera obscura (Latin for "dark chamber"), an early mechanism of projecting images where an entire room functioned as a real-time imaging system; the modern camera evolved from the camera obscura.

A Shutter

In photography, a shutter is a device that allows light to pass for a determined period of time, for the purpose of exposing photographic film or a light-sensitive electronic sensor to light to capture a permanent image of a scene.

The Aperture

In optics, an aperture is a hole or an opening through which light travels. In Photography this can be measured in increments called f-stops.

The Lens

The Lens of a camera captures the light from the subject and brings it to a focus on the film or detector.

Exposure control

The size of the aperture and the brightness of the scene controls the amount of light that enters the camera during a period of time, and the shutter controls the length of time that the light hits the recording surface. Equivalent exposures can be made with a larger aperture and a faster shutter speed or a corresponding smaller aperture and with the shutter speed slowed down.

Evaluation

For our photography induction assignment we had to create a pinhole camera out of a cardboard box or tin, paint it black on the inside and completely light proof it.
This technique is taken from the ancient words ‘camera obscura’ which is the ancient Latin words for ‘dark room’. The box acts as the dark space where the photography paper sits hidden from the light to stop it getting exposed so that a good picture may be captured. The paper is concealed in the box which is then light proofed and the only way light can get into it is through the pinhole in the front of the box.

Before taking pictures we had to estimate how long to leave the box open before the paper would spoil. We estimated this by calculating the light readings and then dividing the length of space between the paper and the hole, by the size of the aperture. My own personal time calculated as 8 minutes inside and 20 seconds outside, however, when I followed this estimation, the paper went almost completely black both times so I minimised my times to be 10 seconds outside and 4 minutes inside.

My pictures came out rather well in the end which im proud with. I took a variety of images which consisted of 2 shots in the atrium, 2 outside, 1 in the library and 1 which was meant to be down the stairs but ended up coming out like the inside of a human lung.
The lung picture particularly interested me because it was so confusing as to why it came out like that.

If I was to do it again (which I probably will!) I would make many more and experiment more with timings and go many more locations to take more interesting and imaginative pictures that have more meaning.
