Pin Hole Project.


Sir David Brewster was one of the first to make pinhole photographs in the 1850s. They then became popular in the 1890s being sold in Europe, the United States and in Japan. Pinhole cameras are used to create photography without using a lens. The lens is replaced by using a small prick sized hole also known as an aperture. An aperture is a hole allowing light to travel into the camera. The size of the aperture and the brightness of the scene control 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 photographic paper this can be measured in increments called f-stops. The aperture was 0.8mm, we worked out the f point by dividing the box length by this figure. The length of my box was 230mm, giving me the fpoint of 287.5. This gave us a reasonably good guess of how long the shutter was to be opened for. Outside, my shutter was to be opened for 40 minutes. Inside, it was to be opened for 2 minutes.

For my pinhole camera, I used a basic celebration chocolate tin. I started by making my tin light proof. I did this by painting the inside and the lid with two coats of black paint. Photographic paper can not be exposed to light, which meant we had to put the paper in while in the ‘dark room’. I rounded photographic paper opposite the pinhole in hope to create a panorama image. I then used a thick tape to seal the lid with out allowing any light in. I used a type of tin foil which I pricked a pin size hole in, this was used as my lens. A simple piece of black cardboard and selotape was used for my shutter.




I set out to take a picture of a sink tap. Unfortunately, i over exposed my photo.
